Blaze Spikes is the only one of the spikes that doesn't have a status effect, however it does have a higher damage factor than either Ice (paralyze) or Shock (stun).

Enspell II's provide MEVA down, limited in use depending on the target you are fighting (and if it is wise to be in melee range or not), but beneficial if combined with Death Blossom, less MACC gear means more potency gear, for enfeebles, and nukes.

Merit spells need a massive change however, either drop them to scrolls or increase their potency. (especially Blind II).
