Mikey will move up next to Rowland and attack (keep in mind that Mikey's attacks are considered magical):

Attack 1:  23

Damage: 11

Attack 2:  12

Damage 2: 10

using savage attacker to reroll that damage   13

Bonus action= unarmed strike

Attack 1:  12

Damage: 8

Mikey attacks twice and launches a flurry of blows for good measure:

Attack 1: 28

Damage 1:  13

Attack 2:  15

Damage 2:  13

Flurry 1:  10

Damage: 9

Flurry 2: 17

Damage: 7

rerolling that damage due to savage attacker feat

9

I forgot to add the bless to attacks.  I'll roll the d4 for attack 2 since that is the only one that should matter.

Also, the elemental needs to make a DC13 dex saving throw or fall prone.
