The character can transmute the outer layer of a target into a highly volatile mix that, eventually, ignites to immolate the target.
The character designates a target within 60 feet, and rolls a D20 and adds his ME score. Another D20 is rolled and added to the target's AR (or PE score if higher.
If the character rolls higher then the target see's his outer layer dissolve into a sticky morass (inflicts 2D4 damage).
1D4 rounds later the target bursts into flame, and continues to burn for 1D4 rounds (+1 at levels 3,6,9,a2 and 15). Burning targets take 3D6 damage per round.
Being on Fire is horrifically painful. Targets must save Vs pain once per round (14+ PE bonuses apply) or suffer -4 to all combat actions and lose one attack per melee (and -20% to all skill use).
Targets may attempt to wash off the substance, every action spent doing so (using more than just bare hands) lowers the duration he will spend burning by one melee round. Diving into water or being doused can cancel this power (40% chance per melee). After combustion has started, the flames can be doused, but spring back to life when out of water (unless he stays submerged until the power runs out).
The power can be used very precisely. At a range of 10 feet or less, the character can target an individual item the size of a screw head or can write in cursive script on a wall. He can can create a line of this substance across section of ground that shoots into a wall of flame 5 feet high. anyone crossing this wall of flame takes 3D6 damage.
Once a target has been targeted with this power, (success or fail) his available fuel is no longer available, and remains this way for 2D4 hours.
