So two things I need to confirm. Does the spell (Trail of Acid and Fire) trigger the Cherry Blossom effect each round or is it only triggered once per spell cast?
To give an example of what I mean here is a link to how toppling spell works with MM.
Next, if it does trigger CB each round how many times does it trigger? Some in my circle think it triggers twice. Once for the Fire damage and again for the acid. I presented a counter to that with the following:
It's "1d6 points of acid damage *and* 1d6 points of fire damage."
Not "1d6 points of acid damage *then* 1d6 points of fire damage."
My point being that you take 2d6 once each round. Half of it's Acid the other half Fire. But I've been wrong before so here I am.
