ghoul buggs

Ghoul has many bugs
1)Pet dying don't start the cooldown, using the spell puts the spell in endless cooldown
2)The energy regen rate is supposed to be 1 energy per decisecond
3)Claw needs to have minimum of 20 enery
4)It is supposed to spawn with full energy/health and no cooldowns
5)It is supposed to have 90% AOE dmg reduction
6)It needs to scale better(same applies to gargolyte and army of the dead)
