Bonus action: Summon echo
Action: 10 slashing damage
Attack; damage: 1D20+6 = [13]+6 = 19
1D6+4 = [6]+4 = 10
1D20+6 = [18]+6 = 24
1D6+4 = [5]+4 = 9
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
