Mentalism
From Project: Gorgon Wiki
“The power of mind over matter: psychic powers! This combat ability focuses on recovery and restoration, but it also has multiple damaging abilities.
Mentalism is a skill that makes use of Psychic energy to both attack and support.
It is learned from Echur in Serbule Keep after completing a few errands.
Further skills are purchasable from Mu in Myconian Cave with sufficient favor.
Group Mechanics
If you're in a group with multiple Mentalists, the same "wave" ability only stacks up to 3 times.
