Section Nine - Boss Soloing
Gnome General- You can solo this on easy and normal almost right away. However, for hard, you'll need to be packing defensive and restorative rings. Try hard when your ring selection is more broad.
OMGWTF- Mantis, Teflon, Hack, Pot Lid, Improbability Sphere, and Meat are epic win in this battle. Meat will give you the HP to survive while your selected buffs give you fantastic damage reduction. Divinity is also worth a mention seeing as you need to defeat several OMG's before the OMGWTF shows itself.
Kat's Kokeshi Doll- POT LID IS WIN. Use it at full rage as soon as you can, and KKD probably won't even hit you once. Meat, Teflon, Pot Lid, Improb Sphere, the Ninja/Chef Set, and Bandage will pretty much seal the deal on any difficulty.
Shewolf- The KKD strategy works well, but Gumshoe is advised to slow She-wolf.
Mama Saw and Papa Saw- It's a drawn out battle, so you definitely need to be conservative with your stamina. Buffs like Ghost and Teflon will easily reduce your damage intake. Until then, they're not really necessary.
For the first few saws, don't worry too much. The damage intake after buffs is nothing to be concerned about so long as you keep yourself healed, preferably with Bandage. Just use standard attacks like Mantis to bring them down quickly while using little stamina. As you build rage, start to pump it into buffs like Meat and Divinity if you have them. Raged Ghost is also helpful.
When Mama Saw comes out, break out the defenses like to save yourself a headache, as well as your life. At that point, if you have active full rage Divinity, spam Bandage to keep your health up.
The same goes for Papa Saw, but he's definitely a good bit tougher. He'll fall with time though, so just keep the strategy going.
Chef Set is pretty handy, as not only can you defend yourself and deal out raw damage with Hack, but can debuff Mama and Papa Saws' accuracy. You really don't want a critical hit from those guys.
Nearly Necessary Rings: Divinity, Persistent Defensive Buff
Recommended Rings: Ghost, Mantis, Meat
Predator Commander- This guy is actually difficult to solo, not because he's powerful, but for the same reason as the general- he's not an instanced boss.
Duneslam- Chef Set + Healing + moar persistent armor = win. My Density is also useful so that you aren't constantly knocked back. This actually isn't a hard battle even on hard mode so long as you monitor your stamina closely. If you choose to bring Density, I would full rage it and Meat for best effect.
Giant Stone Coatl
Bring Iron Will to deal with the Masks and Witch Doctors.
Phase 1- Feathered Coatls - Simply defeat the Coatls. This isn't very daunting. The first mask will then attack.
Phase 2- Tinies - This isn't an annoyance save for on hard mode. 3 terrors will appear followed by a witch doctor (reversed on hard mode). On hard mode, witch doctors have so much will power that they pull a jedi-mind trick and may render you unable to move or use your rings for a few moments. The second mask will then attack. No problems.
Phase 3- Vases - While the vases pack a punch, if you're properly buffed, they aren't worth mentioning, even on hard mode. After you've killed enough of them, the third mask will attack.
Final Phase- Giant Stone Coatl - Now here comes the tricky part. I'm going to tell you right now, if you don't have Divinity and proper persistent armor buffs, your chances of victory are slim on hard mode. On the lower difficulties however, Stoney's attacks are more spread out and you can kneel out of his range to make up for lack of Div. Just be sure to watch so that he doesn't warp you to him while you're still kneeling, or you'll be obliterated. If you have div and the proper buffs, you're in luck.
Kill his minions until either a Tiny Terror or Feathered Coatl spawn. Do not kill it. Solo, only one animated can spawn at a time, and you want it to be a weak one. Save your rage until it's full, and use it with Divinity! When your stamina is restored, keep giving him a beating until your health or stamina run low. Retreat to the entrance of the Throne Room and make sure that stamina's regenerating! When Stoney gets low on health, he'll switch to his lightning attack, and will do significantly more damage, so be aware. Just keep up the assault up and you'll do him in.
I'll be looking into alternative strategies. Let me know if you have one.
