Heretic of The Seventh Circle
I don't see at-will levitate as bad. Fly up, and rain down eldritch blasts from above.
Jump is pretty meh.
I think the ones that need help are the the 1/day ones.
Fair enough, I guess levitate is ok. I've just seem Jump make a difference more often, at the table, whereas levitate is usually much too slow.
The 1/day spells are pretty...meh. If it were two spells per invocation, I could dig it. Or if you had CHA/day "daily" slots, and invocations added multiple spells that could be used with them. the fact that they use your warlock spell slots is the big issue, IMO. There are too few. If they are going to use regular warlock slots, they need to be short rest like other warlock spells.
OK, so, how's this:
When you learn an Invocation that lets you cast a spell with a spell slot, you instead can use that spell once without using a spell slot, and add it to your spell list. It does not count against your spells known.
Also, your patron spells do not count against spells known.
Would that give the warlock too much?
