Lots of fire and lightning evocations.

Various buffs

There's plenty of non gem combat magic, just a question of what exactly you are trying to do and with what nation.

It's easy to set up thunderstrike (or orb lightning) spam with various air nations.

Same with falling fires/flare/fireball for various fire nations.

Also all the astral 100 accuracy spammy spells to deal with thugs/SCs (and things like incinerate or frozen heart there as well).
