1) Works, all casting classes at least should have it, and at least opens more classes of alts to have that can locate, if GM's don't have it.
2) Lets discuss? What does everyone think about more elementals? what tiers should they be? should tiers vary with your tier? maybe have elementals work like golems to a point? Your elemental is summoned via the spell, and can gain levels, more you have it out, gain exp from kills lose exp from deaths. Just an idea. Again all ideas welcome!
3) Simply up for discussion, do you want to see the powerful poison spells available? If so what classes, or no classes, and on an item, or castable via scroll of sorts.
4) I'm in favor of a dispel magic, however if you cast it on yourself to remove a spell and chance of magic bubble, you could be stripping away all of your own buffs, more of a cast on self for adverse magic on you, and on another to remove any spell randomly perhaps?
