Fire Wall + Circling?

So, it’s now known that Fire Wall number of hits is based on the enemy’s AoE defense ratio(I.E, a Firewall lv15 will do 9 hits/tile to a medium sized target) so my question is, what’d happen if circling was in effect and that target had its AoE def ratio lowered to negative values(Or maybe 0, if not possible)?
Can any1 test this out for me? thanks!
