Usage: (numbers are unfocused)
Must be cast on a mob with mana. Costs 600 mana to cast, and removes 300 mana from the target.
Each member of your group that has mana will recieve 300 mana over a 4 tic period including your self!
if solo; hate self healers? this spell effectivly costs you 300 mana to remove 300 mana from the enemies pool.
if duo with another caster: costs you 300 mana to 'twitch' your partner an added 300 mana, compared to 2 casts of Sedulous Subversion costing a total of 800 mana for the same amount given, AND it has the added bonus of removing the 300 from the mob!
for a group of 3+: the mana benefits of this spell are fantastic for example with a full group, it costs you 300 mana to remove 300 mana from the mob AND provide 300 to each member. thats a cost of 300 mana to give to team 1500 mana!!!(assuming all casters).
this spell resists at -200 against disease so casts well on most mobs, but a resisted cast will cost you a whopping 600 from your bank...
hope this clears up any ambiguity caused by some other posts =)
