The orbs are quite different from acid arrow. Acid arrows deals a pretty small amount of damage, but does it over multiple rounds. The Orbs deal a lot of damage, all at once. Plus, it makes no sense that a conjuration spell would be able do deal sonic, electricity, force, or cold damage. Acid makes perfect sense (but should do more acid arrow-like damage - spreading things out over multiple rounds), and fire could work (basically creating alchemist's fire), but other energy types should only be indirectly accessible (e.g. by summoning something that uses it as an attack type).Mistwell said:Second, the orb spells. How are the orb spells really different from Acid Arrow? With metamagicing, you could basically replicate almost all of the orb spells with acid arrow. All the orb spells do are expand on an already accepted and balanced spell from the core books. People talk about them as if they are broken, but once you see them in play I've never heard anyone actually complain about them as being over powered (much like a lot of people did with the Warlock before seeing them in play).
If I had written the Orb spells, I'd probably have made them do d8 per level (damage spells are underpowered, and I think a 4th-level single-target spell should do more damage than a 3rd-level area spell), be evocation spells, and had SR affect them.
