AST mana problems.

[Donarudo]

He put the "reduce mana" in quotation marks since he meant it as indirect reduction. Bole decreases the amount you have to heal, Arrow/Balance increase DPS (shorter fight = less to heal), Spear affects Luminiferous Aether's CD, and Ewer is pretty obvious. Spire is the only card which will most likely neither affect your MP costs nor have a noticeable effect on the fight length, hence 5/6.

I disagree with you. He/she specifically stated "conserve mana" they do not specifically reduce mana cost. Also where does it state that Spear directly affects Luminiferous Aether's CD? I will state again only 1 of those six abilities "directly" affects MP cost. It still does not address the underlying issue that AST's do have mana issues even using proper buffs to "conserve mana" as was stated in his/her post.
