Mana gems grant much more energy, but you get less health from potions.
- Renders health potions virtually useless (1 or 2 HP per potion).
- However, one mana gem alone can fill about 5x the normal amount.
- Corvus can get great use out of this perk as health potions are useless for him to begin with. Combining it with Mana Burst and Overload can yield some amazing results.
