I would like to know if "Two weapon defense should now grant 5 Physical Resistance" will stack with "Ultimate Mountain Stance Martial Arts Stance: The unyielding mountain focuses on endurance and defense. Ultimate Mountain Stance grants +4 Constitution, a 20% boost to AC, 15 physical resistance, a +70% Insight bonus to melee threat generation, and the critical multiplier of all weapons you use is increased by 1 on rolls of a natural 19 or 20, at the cost of -2 Dexterity and -10% movement speed. While in Ultimate Mountain Stance, you gain 'Get Hit Effect: Gain 1 ki." Do all forms of physical resistance stack or will there be different types like competence bonus to physical resistance or exceptional bonus to physical resistance etc...?
Also, stalwart says "You may expend a Fighter armor boost to become a bastion of defense", does this mean there will be a cooldown on it?
Any other helpful knowledge on this subject would be appreciated. Thanks.
