At long last, I've updated my four part strategy guide for v1.0.10, so it's high time I also illuminate the secrets of the six new skill sets in Realm of the Diggle Gods - and provide some fantastic new builds to go with them! UPDATE! five additional builds for RotDG, and updated to include YHTNTEP content!
Big Game Hunter
BGH is a Warrior skill, so it's a great way to boost your melee damage and HP. Level 1, before you've put in even a single skill point, will give you +8 xp for every "animal" kill. (It's actually +16, but it only happens half the time.) That's pretty sweet. Level 2 gives you the "Butcher" effect, which causes animals to sometimes drop meat. Not great meat - but it's a bit of HP regen which works all game. Level 3 is the disappointing "Lure" - which provides a minor debuff to nearby enemies. Why would you use this instead of just hitting them? Level 4 gets us back on track with a decent damage boost and bleed effect, as well as a big accuracy boost and stealth boost! Very interestingly, this damage scales with stealth - giving players a reason to max Stealth. Combine with Piracy's Mist of Corsair, maybe? Level 5 gives us the ability to summon 4 diggle "hounds" - which is just as awesome as it sounds.
This makes BGH a pretty good random skill to take and not invest any points in - or a good skill to put your first 4 points in and kick ass with your diggle hounds. Both totally valid options.
This is probably the funniest skill tree in the expansion. Unfortunately, the strong humor seems to have trumped utility in a few cases.
The first skill teleports away a nearby enemy. This is great - much more useful than Mathemagic's teleport, which affects YOU. The second skill is the FANTASTIC "Cure" - which is a minor heal, but also acts like a potion of purify - it removes all negative effects from your character. This is an absolutely fabulous way to get around those irritating drawbacks from Killer Vegan or Necromancy!
Level 3 Gives a decent - but dangerous! - chemical AoE blast which doesn't scale well at higher levels. Next is the Dampening Field of Angst, which does minor damage but mostly acts as an anti-magic fields - to stop enemy spellcasters! This spell won't get a lot of use, but when it does it is an absolute lifesaver.
Level 5 gives the Sigil of Whatever - a rune which damages and pacifies an enemy. Pacification doesn't quite work as well as you think it should - enemies will re-target you quickly if you are still nearby. Level 7 is a bigger targeted pacification effect - if you like the Sigil of Whatever, then you should get level 7 as well. If the Sigil isn't working for you - it's probably best to avoid it. Level 6 is a modest self-buff which works against exotic damage, and provides 2 armor. Meh.
Curse of the Werediggle
This is a Rogue Skill (unfortunately!) and it's a pretty weird one. Level 1 gives you the ability to transform into a WereDiggle - giving you a hefty damage bonus of +5, dodge +5, armor +2. However, while in Were-diggle form you lose the ability to use any other skills, and lose all bonuses from any other skills. This is a HUGE penalty, which makes being a Werediggle, usually, a bad idea.
If you need a throw-away skill, Cures of the Werediggle is a fantastic way to get your first level's worth of XP in absolute safety. This means mages might flirt with it just for level 1. It even adds to your Savvy, which helps reduce spell costs. Not bad.
On the other hand, if you are willing to go whole-hog (whole-diggle?) and base your entire build around it, being a Were-Diggle is pretty cool. Level 2-8 give a mix of interesting skills, notably the ability to lay diggle eggs (omelettes forever!) turn invisible, and bash through walls every 2 turns (way better than Golemancy's Digging Ray!)
This is, hands-down, probably the strongest skill tree in the game. It's also a bit irritating to use. Killer Vegan essentially punishes you if you eat animal products (eggs, cheese, meat) or attack an animal in melee range (animals are about 30% of the enemy types.) These penalties are severe, and last 200 turns.
In exchange, animals WILL NOT ATTACK YOU - which lets you just walk past a ton of enemies. This means you don't get XP for killing them, but it also means you blow through areas pretty quickly. To be clear - you can still kill them, just not with melee attacks. That's what level 2 is for - it allows you to turn any nearby animal into a pet - who can kill animals without penalty.
The real power of Killer Vegan, however, is the absolutely INSANE stat bonuses it provides. It gives +9 Burliness and +9 Nimbleness - which is essentially like being 8 levels higher than you are. You'll also get a +5 Righteous Damage bonus, which is unresistable and applies to both melee and ranged attacks. And the last skill point gives you an ability which lets you ignore the penalties of breaking your Vegan Pact. That means you can save your cheeses, eat it all in a big non-vegan binge, then eliminate the consequences for doing so. Amazing.
Piracy is a Rogue skill set, and it's a pretty amazing one. It doesn't provide any traps skill, otherwise it might actually threaten Burglary for most-useful utility skill.
At level 1 Piracy gives the fantastic "plunder" skill, which gives you a 10% chance of finding a gem on your enemy's corpse. That's not only a ton of money - it also helps a lot of those weird crafting recipies for which you've been hoarding that ruby all game. But the real power comes at level 2.
At level 2 Piracy gives you the swashbuckling skill. This gives you +75 counterattack for 4 turns. If you have ~10 counterattack already, this basically makes you impossible to hit for those 4 turns. Counterattack works on everything that hits you - so it can turn a "I'm surrounded" moment into "they all killed themselves" moment. Amazing, and always worth getting ASAP.
Level 3 has a really useful and thematic spell - Mists of the Corsair. This summons a cloud which confuses and pacifies enemies - but more importantly gives you +20 dodge and +50 stealth for a few turns. This works like invisibility for the most part - but it's also just a great way to max out your dodge chance in a tough battle. Level 4 gives the Black Spot - the only debuff in the game actually worth using just for the debuff effects. It gives huge penalties to defense, counterattack, dodge, armor, and pierce armor. Toss this on anyone you think might give you trouble, and watch them shrivel.
Level 5 is a bit of a divisive skill. I love it, but it's not always a useful thing to bother with. It fires a cannon, which deals wildly different damage depending on how lucky you are. The baseline is 16 damage, but delivered in 3 distinct damage packets - so if your opponent has 3 armor you will deal only 7 damage(!). But then you have a decreasing chance to deal up to 4 additional salvos of damage which, depending on your target's armor, might mean a total of 80 damage (!) or as little as... nothing. Cannons can now fire in all four cardinal directions - which makes me love this even more.
In addition, this skill spawns a cannonball on your target, which is a pretty decent thrown weapon.
This is a really weird tree - the first 3 skills give you heavy anti-demon powers fueled by righteousness. But skills 4-7 take away those powers, as you give into demonic forces and become a demon yourself. This is absolutely a skill you take 3 points in or 6 points - there is no in-between! This is a Rogue skill - though it buffs your magic, and has a bit of a melee-focus.
Level 2 gives you damage bonuses when you are hit in melee - a nice synergy with Berserker Rage.
At level 3 you get circle of protection - a real high point for the Demonologist tree. it provides huge bonuses to exotic damage resistance (including fire!), block, armor, regen, and magical defense.
Now things get dark... at level 4 your lose all your Righteous resistance, and instead gain the Abyssal Fire skill. This is a +2 damage (fire) which also procs burning effects when you hit or are hit yourself. Decent, but not worth giving up your old skills for. If you take this it's because you're looking to fall further down the dark path... like to level 5, where you gain the ability to summon a swarm of demon minions! This puts a bunch of debuffs on you as a penalty - but who cares!
Level 6 gives you the unique (and very welcome!) skill to remove corrution effects from your equipment. This only happens when you fight certain high-level enemies in melee range. At level 7 you have fallen really far - to the point where, sometimes, you just turn into a demon. In this form you get +11 melee damage and +5 armor, but your magic stats take a huge hit. This can happen when you hit, when you are hit, or when you cast a spell... so it will happen pretty often. You're really in this skill tree for the demon transformation by this point, so enjoy the huge melee buff! Oddly, this skill ends up being a bit like a reverse Were-diggle tree, where the transformation happens at the end.
The Strongest One in the World - Maces, Killer Vegan, Thrown Weaponry, Smithing, Berseker Rage, Tinkering, Piracy
This is all about synergy. Killer Vegan and Smithing give you big bonuses to Burliness - which increases your thrown weapons damage. Piracy gives you infinite cannonballs - to throw! Smithing and Tinkering give you thrown weapons - to throw! Tinkering also gives you Power Limbs, which increase melee damage (and thrown damage!) Berserker Rage increases thrown damage and armor. Maces deal knockback, so you can throw.
Get Animal Friend first, so that you can get all the XP from animals on the first floor. Get Smithing 3, Maces 2, and Thrown Weaponry 3. Piracy 2 is also a good way to avoid damage. Once you've made it that far, you can focus on Tinkering for power limbs + trap XP, or get more Killer Vegan power to increase your strength. You'll find that you can melee fantastically well with this build - almost as well as a dual-wield build. The difference is that you have weak defenses, so you need to rely on Piracy and your heavy thrown weapons to keep you out of tight spots. Softballs are 2-hit-killers with this build, so buy them and keep them handy. Remember that being a Vegan only means you can't hit an animal with melee attacks - softballs are totally fair game.
Go! Go! WereDiggles! - Curse of the Werediggle, Berserker Rage, Viking Wizardry, Assassination, Smithing, Archeology, Big Game Hunter
So, being a Werediggle cancels all your stat bonuses, eh? Then let's take some skill trees which rely on proc effects to do their work!
Viking Wizardry we're only using for the amazing level 1 spell Power of Magic Steel. Cast it before your first fight, and just leave it on forever. It's +2 electrical damage, which will help you rip through the early levels. Smithing and Archeology are skills you use between fights - although the Fedora works great while you are in diggle form ;). Big Game Hunter, Berserker Rage, and Assassination all give their bonuses while you melee it up as a diggle, so go nuts.
You will suffer from weak defenses eventually, so save your steel to make some heavy armor with Smithing. Level up Big Game Hunter to gain the ability to summon a swarm of Diggle minions! BGH and Werediggle form are really the only skills you need, along with a generous helping of Smithing. Everything else can come later.
Superman - Unarmed Combat, Artful Dodger, Master of Arms, Astrology, Burglary, Big Game Hunter, Perception.
This build makes your faster than a speeding bullet, able to teleport, ambush, and fire EYE LASERS.
Start with 1 level of unarmed combat, for the knockback, and a level of Burglary, for the lockpicks. Use Suit Up to keep your health regen up as much as possible while you rush to get your eye lasers. Once you have fiery death at your command, you have three options: go for Knightly Leap, go for Ninja Vanish, or work on Big Game Hunter to get your diggle minions. You need at least one of those options to keep the heavier enemies off your back so you can work your magic on them.
Remember, your lasers get better as your perception skill increases. BGH gives you +2, and there are several pieces of equipment which can help you as well. Is this the strongest build ever? No. But it's pretty awesome.
