Moth
Break off a Moth-shaped blob, I'm joining battle.
I send a magic missile at my clone. BR 2+1= 3 damage.
Next round, I pull out my sword and attack. If he's anything like me, he's an adventurer (hopefully...)
BR 8 doesn't hit...
Round after that another swording.
BR 8 or 10, I can't tell if blogroller rolled another 8 or what. I'm pretty sure a 10 hits. If it went down that way, BR 1 for damage (+1 strength, + 1 or 2 depending on adventurousness of the blob...)
