If you are the main tank, and you aren't doing some weird mega dodge bonus build, I'm gonna assume most of your AC comes from your armor and incorporeal undead go straight through that.
Haha! Yeaaaa my guy was actually supposed to be more of a comic relief character with our inquisitor being the tank, but he decided he doesn't like melee and is building pure range now. So I kind of got thrown into the tank role. Basically the idea behind my guy is this:
Poot the Wizard(Barbarian)
He's a half-orc barbarian who's clan was caught in the middle of a mage war. Almost getting wiped out, they managed to escape and rebuild. But, instead of hating magic, they saw the true power of it! They decided to become wizards themselves. Only problem, they're pretty stupid. So while they THINK they're practicing magic, they're really not. So now he thinks he's a wizard on a quest to find powerful magic. His main magic attacks so far are Magic Missile: He throws a javelin yelling magic missile. Fireball: He lights a flask of oil on fire and throws it yelling fireball. Currently he's using a heavy mace as his wand and beats people with it. And every once in a while he can use elemental rage to light them on fire! If one of his magic spells miss he automatically goes into rage for at least one round.
So because of this he has high Dex from all his throwing, decent Con and decent Str. Currently we're level 5 and I have 18 Dex, 17 Str, and 15 Con. (7 Int Haha!) I'm pumping Str up every ability increase now to boost my damage. Plus with our campaign, we just released an unknown and powerful evil that's causing the undead problems, but in doing so we just gained 1 tier of Mythic.
I'm looking for a longsword right now cause of the undead resistance to blunt weapons, but with my str, power attack feat, mythic power attack feat and using two hands for attacking, I'm doing 1d8 + 13 damage a hit without rage and have an AC of 23. I've been able to one shot most zombies so far, so I think I'm doing alright on damage for now. Could be better if i hadn't made my guy as a joke. Haha! Once I get Mythic Titans Rage, vital strike, and mythic vital strike I'll be doing crazy damage with lots of attack of opportunities and still decent AC.
And yea I'm still working on what equipment would help me the most. So far I have an ioun stone dusty rose, my mithral breastplate armor, a cloak of resistance +3, and a ring of protection +2.
What I was thinking about going for eventually is:
Head: Jingasa of the fortunate soldier
Neck: amulet of natural armor +X
Shoulders: cape of free will +X
Waist: belt of strength +X
Wrist: vambraces of defense
Boots: boots of speed
Hands: gloves of storing (for instant magic missiles!!! XD)
So yea, I think I've got pretty good AC for level 5 and decent resistances. A lot of the items are just a little boost to AC, Str, or just for flair. So instead I figured why not spend a little extra to make me immune to drain effects? Thought that might be a bit more useful. Sucks I can't throw it on boots or gloves, but I guess armor wouldn't be a horrible choice. Although, doing ghost touch sounds like a really good idea too. I'll have to think about it some more. Thanks for all the great ideas!!
