If I play an Armagio and have it use Gravity Pull, when a monster with 5 HP attacks, the damage to Armagio is not blocked.
I didn't bother to grab a screenshot before I decided to report this.
I am a bit unsure if this is a bug, because of the wording on Gravity Shield.
"any creature that has more than 5 HP's is unable to reach you."
If it isn't, I am sorry for the inconvenience, but I figured it better to err on the side of caution.
