Super Saiyan 4

A saiyan that fully harnesses the power of their primal roots is the pinnacle of warrior strength, defense, and ki. When you become a Super Saiyan 4, your whole body transforms, becoming more primal and ape-like. You can become a Super Saiyan 4 in addition to any other Super Saiyan transformation. When Super Saiyan 4, you gain the following benefits:

• You gain an additional +3 to all of your Super Saiyan bonuses.
• Once per short rest, you can reduce damage you take to 0, no matter the type.
• You gain an additional attack action on your turn.
• Your movement speed increases by 100 ft.

With this mastery of your tail, you also gain a +2 to Strength, Dexterity, and Constitution, even in base form.
