Annihilation

The caster becomes a beast of the void for up to 4 rounds, with the following effects:

• The caster gains 1d8+1 extra health, which vanishes at the end of the spell.
• The caster gains an extra 20ft. of movement speed.
• Enemies within a 40ft. radius must make a Dex saving throw of 13, receiving 3d10 points of necrotic damage or half as much on a success. They must do this for each subsequent turn in the field.
• Pummel: The caster has fists of void and a range of 35 ft. The fists deal 1d6 points of force damage.
• Block: As a reaction, the caster reduces damage taken by 1d12, rolled for each attack made against them. For each use, their movement speed is reduced by half on the following turn.
• The spell ends on the caster's next turn when there are no enemies within the radius, or after the 4th round of the spell.
