Hmm, see if I can dump some simple ideas for you. Not going to bother with names.
1. Very quick small red orb shoots forward, if it collides with anyone it does moderate damage (1-2), but upon reaching its destination is explodes dealing 30 AoE damage split amongst all targets close enough, as well as leaving fire that deals 1 damage per second
2. Skull-like projectile that when colliding with a enemy banishes them increasing damage taken by 10%, for every additional unit hit all affected units get a stacking debuff increasing damage taken by 2% per application
3. Going against the grain here, but this spell targets a person instead, dealing no damage directly but causing 8 small orbs to fly off from his position that do 5 damage to any person they collide with and repeat the process upon collison (creating 8 more orbs that behave the same)
4. All these non-point-target spells are coming to me. But another one is creating a shadow of the caster that casts every spell they do in an appropriately mirrored location but all damage done by the shadow is halfed.
5. Basic fireball goes to a location, upon collison it explodes sending flame walls erupting out in an X shape that do minimal fire damage when you stand in them and dissipate rather quickly, but upon collision it applies a a living bomb debuff, were no damage is taken, but if the person takes damage within x amount of time they take 20-30 damage to themselves and 10-20 damage split in an AoE around them
6. Instant ice-effect goes from the target to the point, the first person in-line between the point and the caster get frozen and then as the frozen target thaws ice orbs fire off in random directions that damage and slow enemies they collide with.
That's about all I can think up right now.
