Concerning this card, if I am running mono-sphere and have an undefended enemy attack strength of 5 go through, and choose to assign the damage to White Tower Watchman instead of killing off one of my heroes, can he be assigned all 5 damage? Or can he only be assigned 3 as that's how many hit points he has, and so I have to assign the remaining 2 attack to one of my heroes?
I have been playing that I can assign all the damage to him, since the attack is not broken into parts, therefore, he just takes more than he can handle and is destroyed, but my heroes remain unscathed.
Thoughts?
