I just realize now bodyswap doesn't work on spell immune creatures. I thought I read somewhere b4 it says its just involve the caster sided creature swapping, so it works on immune creatures as well. Have we changed that? nobody updated anything.
If it changes, it should still copy the opposite side spell immune creature. Just like living bomb, the creature still blow up.
Then, again, what about evolve it copies spell immune as well.
I believe body swap (swamp) was changed in the last update. Living bomb (fire) never affected magic immune creatures opposite the target. Evolve (forest) does not affect the creature opposite the target, so it can be used if the opposing creature has magic immunity; and it does, i think, copy all features including immunities. However, creatures like shadow dragons (underworld) specifically state that only features described in text are copied -- thus immunities (and features like evasive an quick) are not copied.
