Experiences on a Spellsword

[BegoneThoth]

That's pretty much the peak of the class though, build gets worse at higher levels as saves and AC go up and that lifesteal becomes less frequent.

Though I don't know why you're able to lifesteal off undead.

[Iceborn]

There is a lot that could be argued of the negative energy imbue.
I think it should not work against anything that doesn't take neg energy damage at least.

[Nitro]

I've always wondered why negative warlock blasts, essences, and now weapon imbues work against undead. Is it some kinda special anti-negative negative or what?
