Life Mana
Jayce felt a tremendous pain shoot up his right arm, causing him to lose his concentration briefly. The mana within his hands was decaying, having the opposite effect of what he had wanted.
The decaying mana seemed to be eating away at his flesh, causing a sharp and stinging pain to assault him. 'What the hell is this?' he thought, staring at the odd phenomenon within his palm.

"Lianna, I need you to manipulate some mana in your hand. Try to turn it into the mana you use to heal, without casting your healing spell." He tightened his grip on her shoulder and asked, showing a sense of urgency.
