It does take up a spell slot as a passive, but it does not say it cannot be lost.
But why are we assuming it can be lost in the first place? You can’t lose any other spells, and it would seem kinda harsh to just lose a lost spell like that
I never said lose the effect. I meant losing the limb.
Ehhh I guess that’s a plausible idea but i think it’d still act as a regular arm and you wouldn’t really lose it, MAYBE when you hit 0 magic but that rarely happens and you can regenerate with a tap anyway
Maybe instead of bleeding you leak magic energy, and still have the physical effects of a lost limb.
magic body bro, all problems solved.
