I want to change text on an aura depending on which buff Blessing of the Seasons will grant next. It cycles between Summer (a nature's vigil sort of thing), Autumn (cooldowns recover faster), Winter (mana regen), and Spring (healing amp), and each of these are implemented as a spell override on Blessing of Summer.

It would be nice if spell - cooldown/charges/count exposed spell id as a condition variable, similar to how BT2 does.
