Answered kicksin damage

What affects kicks?
Physical kick damage is calculated from Strength, Dexterity, Skill Bonuses (kicks and Pally Auras), Boot Damage, and %ED from equipment, only. This is not including mods such as elemental damage. Weapon physical damage is completely useless, meaning you want to choose weapons for other mods. Here are the other properties that do work with kicks:

Crushing Blow, Open Wounds, Slow Target
Magic, Elemental, and Poison Damage (not displayed on the character screen)
Knockback (Dragon Talon and Dragon Tail have their own knockback, only works for Dragon Flight)
Life/Mana steal and Life/Mana after kills
%Chance to Cast on Attack/Strike
+% Damage (except from weapon)
+AR (except on your weapon)
+% AR (from anywhere)
Blind, Freeze, Prevent Monster Heal
MF and Gold find
Weapon Range

Properties that do not work with kicks:

Deadly/Critical Strike
+% Damage to Demons/Undead
+ Min damage, +Max damage, or +X Damage (so no max damage charms for kickers)
Bonuses from Claw Mastery (boots aren't claws)
