So, in Celestia I've noticed a glitch for the Physical Attack with the Shadow-Web Wraiths, when they do it, they just sit there and do nothing in the middle of the battle board and -This part I kinda like- you don't take any damage, I know it's a kinda nice glitch for when your in battle but it could lead to big problems in the end.

It's not really a glitch with no damage. The damage just occurs next round and isn't shown on screen. Next time you see it happen watch your health, it will drop by a couple hundred at the start of the next round.
