Sanctum of Thought

Sanctum of Thought is a notable passive skill that reduces the effect of critical strikes on you. It also grants increased armour and reducing the effect of curses on you.

Mechanics
The bonus granted by this passive skill causes the character to take reduced extra damage from critical strikes. This is a modifier on the percentage of damage over 100% that an enemy inflicts with a critical strike on the character.

If  and , then

The enemy's effective critical strike multiplier is 140%, thus the extra critical strike damage is reduced by 20%, but the total damage of the critical strike has only been reduced by 6.67%.

Since the default multiplier for monsters is %, for most monsters each 20% reduction would reduce the multiplier by 6% (20% of 30), which is 4.6% of total damage.
