As for the next's day's activity, Theon will purchase good meals for both evening meals (1gp) and common meals for both morning meals and the noon meal (9sp).
He will then spend 100gp on two vials of antitoxin (knowing what is likely to show up in jungles) and 50gp on a potion of cure light wounds (assuming they can be found).
Total
200gp-4-1-100-50-9sp=44 gp 1 sp added to character sheet.
The meal prices given are for a day's worth of meals so feel free to give yourself equivalent money back. Unless you want to be in the great tradition of feckless spending heros such as Fafhrd and the Grey Mouser. All those things should be available; I'll write a short rp of your shopping trip once we have all other requests)
Items up to 2000gp value can be purchased in Coral Bay (it's full of merchants after all) with DM discretion.
The following are available from the alchemy list (other items on that list are deemed not to exist):
Acid
Alchemists' Fire
Antitoxin
Holy Water
Smokestick (I just like the idea of them for some reason!)
Artemis will purchase one anti-toxin.
As for the time spent between now and boarding, he'll spend 30gp in lavish extravagance. Adventurers should entertain themselves to the fullest for tomorrow they really might die.
If there's a temple to Nimea in town, Anemone will head on over and buy scrolls. I want a scroll of Lesser Restoration, and two scrolls of Cure Light Wounds. That blows the 200, if I'm not mistaken. She'll spend some of her own cash to buy cases for each of them too. Can't have humidity spoiling them now.
