DEBUG :

- Debug the armor formula that collided with objects that deal damage per second to the player.
- Complete change of all damage formulas, armor, lifesteal, heal, invulnerability shield.
- Related to the change in damage formulas, items that deal damage per second will no longer deal the difficulty level in damage. (Collision with armor formula)
