The new anti-magic sphere from the bard power list
is pretty much broken.
The description says “prevent magic damages by 20%”
but actually, it’s way worse than that :
even if you pound your enemy with 100 damages, and it only has 2 life point left,
it will survive, because the 20% reduction seems to be applied after the damage get automatically reduce to the number of life points left for the enemy.
As a result, such target is impossible to kill with magic spell.
Looks like a bug to me : a 20% magic damage reduction from 100 damages should still allow 80 damages to get through, so the 2PV bugger should die.
I see this bug being more and more abused in defense teams. If unfixed, I expect it to become widespread shortly.
