"Enough," curses the dwarf, as he shifts the axe in his hand, and hoists it up from between his legs, hoping to catch the cloaker unawares. He does this, conscious that if he misses his axe might well sail past his face and back over his head.
NOTE: if I have to re-summon to be able to attack - i.e. the cloaker is too high above to be hit by jumping up, take only the first attack
EDIT: just realized the thing dispelled the echo...so if AC 19 hits 10 slashing damage - use the other roll if advantage or something
Umbril double slashes into the body of the creature, leaving heavy slashes in the body and wings.
The Cloaker Disengages from the fight and flies towards the door to the north, bashing through and only a second later you hear a second second heavy smash. Then, nothing.
