H
Below is every MMO & MMORPG term beginning with the letter H:
Heal
A spell or skill that restores the health of the target. Could also be a call for help. If a player yells ‘heal me’ or even ‘heal!’ it means they are about to die unless another player restores their health.
Health
A common attribute, also called hit points or HP, that signifies the character’s life. Usually when health runs out, a player dies.
IMHO
Simply means ‘in my humble opinion.’
