EVENT INCURDAMAGE

EVENT_INCURDAMAGE is a constantly running event that checks for any damage inflicted into the player, and if the player is wearing any armor[SHIELD], it will split the damage into 2/3s to Health and 1/3 to Armor. If you add "setvar RETURN -1" to this event, armor will not be factored into the damage automatically, and you can create your own code for how armor reduces damage.
