Summoner would fail in this game if it had a perpetual cost.

What are all you melees complaining about... staying near a boss that spams aoes. If Avatars had a perpetual cost + the solid cost to summon the avatar alone they would be out of mana in no time flat. So what happens when an avatar goes near the boss that spams aoes they'll go down fast too. Oh look now the summoner is useless cause they have a perpetual cost and drained their mp.

It should cost MP from the summoner only to summon the avatar, and any spells it uses, not abilities. Abilities should require tp use. With spirit dart attack on summon to build tp safely.
