 The frog drops to the ground with a thundering crash.

@yoku, you still have the arrows and Ben still had his scroll/slot. 

I’ll give you guys the rest of this round and one more to recuperate. Is there anything you guys want to do?

Ha ha totally missed there would be more fights, should have been a bit nicer to the dragon! (And yet I was worried it might happen hence Counts healing)

So I think that puts up to 5 rounds of haste and potion of invulnerability used

Dragon will drink a potion and Count will use his action to feed the dragon a potion as well.

With a total of +30hp for Vermithrax

Also get close by each other again and the dragon gets 12 Temp hp

How long until Vermithrax breath weapon is recharged?

 It’s recharge 5-6 so I shoulda been rolling that each round.

it’s probably recharged by now.  

Dolrik and Rawrer consume their Potion of Invulnerability.

He scritches under Rawrer’s chin and behind his ears.

”Team! It has been my utmost honor to fight alongside each of you. May we each find our way home or into the halls of our gods as heroes!”

Dolrik takes a position near Count (for the aura) and Rawrer begins his dance to distract.

End of turn 6:

HP D//R: 87/96+11 (or 13) thp // 6/22+14 thp.

Sanctuary (on Rawrer): 6/10

Bless: 6/10

Twilight Sanctuary: 5/10

Resistance to all damage: 1/10

Yoku drinks a greater potion of healing 20 hp, then a potion of invulnerability 

Ben drinks two regular potion of healing for 20 hp

Sorry, I assumed it was a round based recharge. I see how to do it now!

It’s all good.

Nadir?
