So if I fight a Wicked Mask and hit it for 9546 damage the first time I meet it in a loop of encounters, the next time I encounter that specific Wicked Mask once the encounters reset my attack should do 9456 dmg?

Also, just thought I'd mention, I got 11 pairs of Dragon Gloves while trying to get the Glass Mask :P
