Choosing which aura to use
I realize that a lot of this will depend on the champs and situation, but which auras are best (and if applicable which depending on situation)?
I am figuring that arena, dungeons and doom tower all have differing needs, but there have to be some auras everyone prefer.
Let's go with a concrete example, I'm playing around in the doom tower right now, and I have the following auras available in my current party:
+24% speed
+25% HP
+33% defense
+40 accuracy
