Dodge[]
Prerequisites - Dexterity 13[]
Grants a +1 dodge bonus to AC.
Agility[]
Prerequisites - Dodge, Dexterity 24, Level 5[]
Add double your Dexterity modifier to AC rather than just your modifier. Still limited by Max Dex of armor and heavy loads (I.E., a character wearing full plate with 18 Dexterity and Evasive still only gets a +3 to AC from Dexterity, not +6, and definitely not +8.). Replaces Dodge.
Afterimage[]
Prerequisites - Agility, Dexterity 40, Level 13[]
Add Triple your Dexterity modifier to AC rather than just your modifier. Still limited by Max Dex of armor and heavy loads (See Evasive for example). Replaces Agility.
Evasion[]
Prerequisites - Dodge, Dexterity 14[]
When allowed a Reflex save for half damage (such as against a Fireball spell), you instead take none on a success. Failure still causes the full amount damage to be dealt.
