The AC of my character is falling far behind her other defenses, and I'm wondering if I have missed out on something basic and important. I am going to post some of her stats as an example to this question.
AC in general
The armor class of a character is basically determined by: 10 + ½ level and if the armor is magical. The class of a character and feats can improve the AC as well, depending on what a player choices to play.
You can improve Will, Reflex and Fortitude through a lot of item slots on the sheet.
Is a magic armor the only way to improve your AC through items?
I am aware of the Armor Specialization feat (which removes penalties and provides +1 to AC) and that you can purchase fey material armor which would give an additional +1 to AC.
What other ways of improving AC am I missing?
The Leader role
My level 24, melee Revenant Ardent has an AC of 32, Fortitude of 35, Reflex of 37 and Will of 37. She wears leather +5 Displacer armor. Her ability scores are Strength 15, Constitution 20, Dexterity 13, Intelligence 16, Wisdom 14, Charisma 24.
To start with I was wearing Hide, but then I decided that I wanted Gambit armor. And Gambit armor only comes in cloth or leather. The property is good for my character because she does a ton of damage when she crits, and that's what I built her for. The reason why I have a Displacer armor instead, is I did not update my item wishlist in time, so my DM ended up using my old wishlist instead.
The other players in my group have far superior defenses for some reason. As an example: The tank does not get hit with 44 against his AC. That of course includes temporary boosts to AC, but it is still way ahead of my defenses, hence the problem: I get hit by monsters at this level by rolls between 3 and 5.
I have run into this low AC problem before with a Shaman character as well.
Are Leaders just not made for close combat?
