Psychic Overload

The overwhelming power of your will is such that you can explode heads with a thought.

Cha 21, Minor Psychic Power, Psychic Power, Major Psychic Power, character level 18th.

Once per day, you can use the mystic connection power explode head (Core Rulebook 87) with a DC equal to 10 + half your character level + your key ability score modifier. Use your character level to determine damage. If you already possess this ability, increase the damage inflicted to 1d8 per character level you have.

Explode Head
You can spend 1 Resolve Point as a standard action to psychically assault the brain of a foe within 60 feet, causing incredible pressure to build in its head. If the target has 20 Hit Points or fewer, its head explodes, instantly killing the target and spreading debris in a 10-foot radius. Each creature in the area must succeed at a Reflex saving throw or take 2d6 slashing damage from the flying debris. A target with more than 20 Hit Points takes 1d6 damage per mystic level you have (maximum 20d6), but can attempt a Fortitude save to take only half damage. If this damage would reduce the target to 0 HP, the target’s head explodes as described above. This ability works only on a creature that has a head and would die from the loss of a head.
