Does using Spirit Symbiosis change your spell list / spells known gained from Emotional Conduit?
I think yes because the feat only last 10 min/lv, you get new spells but lose the old. And the old spells would be uncastable until the feat ends (as they would be only return when emotional focus comes back).
Now, I guess since the new ones are added to spells known: you would be stuck casting the new ones.
So, it would be cool way to get diversity in your known spells.
