This was off another MMORPG I played where white mages(Druids) were able to raise people when they died instead of them having to respawn and loose everything. If a druid raises you. You kept more of your exp instead of loosing it all to dieing. You might make it 25% or 50% of your exp is saved if you are raised by a Druid. You might also be able to keep your gear. See as you are raised from the spot you died at.
Raise/Revive
GP cost - 150
pro's - Keep some of your exp and or armour.
con's - Usally people charged others to be raised. 10k in gold to raise you and sometimes you got ripped off.
There was also another command that you could cast raise on yourself or someone else that would reraise you automaticly if you died but the spell would only last 1 hour after being casted before it wore off. GP cost was also 150.
