You cause creatures to take extra damage when you affect them with a power that has the acid or fire descriptor.
Benefit: To use this feat, you must expend your psionic focus. The acid or fire effects of the affected power adhere to the creature, causing more damage the next round. When a creature takes acid or fire damage from the affected power, that creature takes damage equal to 2 × the power’s level at the start of its next turn. The damage is acid or fire, as determined by the power’s descriptor. If a burning power has both the fire and acid descriptor, the manifester chooses what kind of damage is dealt by the burning power effect. Using this feat increases the power point cost of the power by 2. The power’s total cost cannot exceed your manifester level.
Powers that do not deal fire or acid damage cannot be used with this feat.
