I was thinking about the same as you, but in simpler terms. I put the group in the cave an hour ahead of you and didn't bother to count Mal's travel or fire-building time. I figure the fire in the forest had an hour to rage before it started to rain. Enough to do some damage. The current month is Revot, named after Reven, this homebrew's CE god of destruction and fire. Revot is the peak of summer; it's hot, and things are very dry. Fertile makings for a nice forest fire. I shudder to think of the far-reaching implications of a large fire inside Teggest. I'm sure the Admiralty will notice it. How they respond, I haven't worked out yet. Good thing I have ten days of brainstorming coming up, eh?
I need for Gamad, Voadam, Brakkus, and Maelicent to level-up, please. I'll work out XP later tonight, but you were all very, very close and these two tough encounters will definitely put you over the cusp and into the next level. We won't bother with resting before you benefit from your level-up. PbP takes too long and I don't want to set the precedent of having to sleep/rest before gaining the advantages of one's next earned level. You'll get it immediately.
I will be downloading a fresh copy of our RG after you edit your character sheets to reflect the new level, so please don't forget to do the edit or you may find me using outdated stats to adjudicate encounters.
HP should be rolled, either by hand by you or using invisiblecastle.com. No need to link to your roll if you use invisiblecastle. If you don't like what you roll, you may take what I roll for you, but my roll is final.
Good luck!
