spell personal force field: when its hit by and offensive spell it could
randomly or with somekinda rep/mastery system give difrent bonuses like
transforming part of the damage mage to you into sps.
Spell drain enemy: rep/skill/mastery/random based system when your drain hits
enemy you disable monsters ability to cast for very short period of time due
hes mana loss.
Spells channelball/types rep/mastery/random based or simular you could
occasionally feel channelled connection with enemy and do the normal dmg and
drain little sps with the blast like 10-30.
Salves: Golems: i dont have experience about them but not many seem to be
using them, making them mebbe more usable (this golem part might be useless
idea on my parts).
