Based on playing an official server, I only know two skills that can heal the emp.
1. Sanctuary
2. Potion Pitcher; which is set to level 4 (White Potion) - need to shift first of course before clicking on the emperium.
But, that was a long time ago. So, not sure if it was changed now.
The following doesn't work:
- Shift+Heal or /ns+Heal
- Slim Potion Pitch
- Apple of Idun (not sure if they changed this one)
Edit:
I think I read somewhere that Gospel works. Not sure though. I have only tried Sanc and Pitch ages ago.
