Grimbald will use his Hunter's Mark on his previous target, the devil now nearest Vakiel silvered bolt Attack: 15 Damage: 15

and bonus action off-hand silvered bolt Attack: 18 Damage: 3

and then scurry sw to the next tree, jumping between trees if allowed/possible 

 Give me an acrobatics check DC 15, assuming it's the South West tree. If it's the north east tree (where Nazim and Vakiel are fighting) then Grimbald is leaping into a burning tree so will assume it's not that one.

End of party turn 2:

Vakiel swings his black greatsword but Nazin steps inside the circle of the sweeping blade and doesn't even bother raising his shield. He gives Vakiel a nasty grin. "I studied your reckless style, Vakiel. I have your measure!"

Augustin tries to smash the Iron Circle Guard with his Red Sceptre, but the Guard gets his shield up in time.

Grimbald's first silvered bolt bounces off the devil 1's armour, but the second one finds a joint. But then falls out, doing little damage. The change of position in the tree means devil 2 with the heavy crossbow can see him now. He scurries along the branch and leaps out to the tree to the south west. It's a big jump but if he pulls it off it puts more distance between himself and the devil with the crossbow, and he can still shoot at Vakiel's opponents. If he doesn't, well it's a bit of a fall. It won't kill him but stories will be made from it.

Rustling Leaves does indeed show how a little more wrist action can lead to a successful bonking. The Iron Circle Guard goes down and does not get up again. He shifts into a more bestial appearance and moves to the corner on the side of the building.

Esa concentrates and the runes on the scroll are more familiar and so casts the fireball spell from it. The devil is unaffected, and Nazin tries to protect himself with his shield.

Nazin Redthorn Dexterity Save: 21.

Nazin Redthorn takes some of the blast on his shield, but being on the edge of the blast helped. The flames still wrapped around him and his skin cooked inside his armour.

"Now it's payback time, Vakiel," he says, and swings his flail around which generates heat. Nazin Redthorn gets three flail attacks. The Searing Flail does an extra 1d6 fire damage on a hit.

• 1st Flail Attack: 27 Damage: 7.
• 2nd Flail Attack: 25 Damage: 12.
• 3rd Flail Attack: 14 Damage: 17.

Then Nazin Redthorn mumbles some litany to Asmodeus and he heals some damage, and the furthest devil shudders a little.

Merregon Devil 1 moves so the tree trunk is no longer provides cover for Vakiel. It then attacks the barbarian with its halberd. It gets three attacks.:

• 1st Halberd Attack: 21 Damage: 6.
• 2nd Halberd Attack: 22 Damage: 14.
• 3rd Halberd Attack: 19 Damage: 10.

Merregon Devil 2 with the crossbow, the one who just shuddered as if in pain, spies Grimbald making a jump for the tree and decides it is too hard a shot. It sees Esa up on the roof and shoots at her instead.

• Devil 2 Heavy Crossbow - Attack: 19 Damage: 3.

Iron Circle Guards:

• Guard 3, already bloodied, stands up from prone and attempts to attack one of the hounds with his spear: Attack: 10 Damage: 4.
• Guard 4 holds his shield up and stabs at one of the two hounds on him: Attack: 6 Damage: 7.

Imp

An invisible imp appears next to Esa after jabbing her with his poison stinger: 

• Attack: 22 Damage: 4. If this is a hit, Esa must make a Con save DC11 or take 7 poison damage, or half as much round down on a successful save.

The black hounds attack the guards:

• Hound on Guard 3: Attack: 14 Damage: 8.
• If a hit the Guard makes a Strength save DC13 or be knocked prone - 11. 
• Hound on Guard 4: Attack: 19 Damage: 9.
• If a hit the Guard makes a Strength save DC13 or be knocked prone - 12. 

The hound leaps and savagely bites Guard 3 on the throat and holds on until the man dies.

Guard 3 had her arm grabbed by the jaws of a hound and got a good shaking but she stayed on her feet. She is bloodied.

Another hound leapes at her jaws agape:

• Attack: 21 Damage: 8.

Her arm already in the jaws of a hound, the last remaining Iron Circle Guard had no chance against the second black hound and she is borne to the ground screaming where the dogs savage her until she her screams become choking sounds and then she is still.

The other two hounds who were near RL and Augustin move at a great pace north to join their pack mates. Then all six large black hounds turn their eyes on Nazin.

Map at end of Turn 2: assumption made that Grimbald makes his jump to the next tree. If he failed then he is prone between the two trees, having taken 1d6 falling damage. Also the tree above Nazin and the devil is on fire.

"Be the squirrel" thinks Grimbald Athletics check 7

YES! 

Grimbald sees the imp attacking Esa, and fires upon the imp. Attack: 14 Damage: 4 and Attack: 23 Damage: 1

and repositions himself to the SW point of the tree.

 Esa casts Shield as her reaction

RL will cast guiding bolt at Nazin.  If it hits next attack has advantage Attack: 19 Damage: 15 radiant damage.

Esa shoots Grimbald a quick look of relief, hoping she can rely on him to take down the imp before it takes her down. She pulls out the next scroll and casts Fireball again. Arcana: dirty 20

33 fire damage
