I had two failed mage runs where I used a wand of warding and had an upgraded wondrous resin. I noticed that the additional zap from the wondrous resin kept destroying my ward. Am I missing something here or is it accepted that the wand of warding is incompatible with the wondrous resin? If it’s the latter then that’s disappointing. Instead, maybe the ward could be immune to zaps procced by the wondrous resin or maybe the zaps could fire at an enemy or a random direction not targeting the ward (if there’s no enemy around) as a special case.
Oh, I have misread your post.
