How to build a barbarian instinctual warrior into a high AC fighter...

[MythTrip]

Am confused on this...I have Adamantine armor which has high AC (9) but limits the max dex to +1. How to build a high AC guy with this start? thank you

You don't want to wear armor with a Instinctual warrior. You want to use the spell mage armor and if possible your own mage armor for a mythic feat.

I have never build one but if it was me i would go with something like this ->

Background: Martial Disciple
Race: Human

STR 19
DEX 14
CON 12
INT 7
WIS 14
CHA 11

Skill:
Mobility rank 3
any

Level 1: instinctual warrior,
Feat: Dodge, Crane Style

Level 2: instinctual warrior

Level 3: Stigmatized Witch,
Feat: Power Attack or something else
Hex: Iceplant
Spell: Mage armor
Familiar: Lizard


So that level 3 damage dealer AC should look like this without any help

Base = 10
DEX = 2
WIS = 2
Mage Armor = 4
Iceplant = 2
Lizard = 1
Natural armor necklace +1 = 1
Ring of protection +1 = 1
Crane style fighting defensively = 4
Dodge = 1
.......................................
28 AC


Shield from a alchemist = 4
Iceplant ring = 2
Archemage armor = mythic level
