Enchanter DoTs not....DoTing?

[Doomapple]

Hey all, back to p99 after a long hiatus and new to the Green server.

Started up an Enchanter and it seems that all of my DoTs (think Suffocating Sphere, etc) don't seem to being doing any DoT - they're functioning as a DD with a debuff instead.

I didn't play Enchanter back in the day so I don't know if this is how it was in early EQ or something, but all the resources I check suggest these spells should be DoTs so I'm just feeling very confused.

Any clarification would be greatly appreciated - thank you!
