In short, let whoever needs it drink the stat potions, and if Shen doesn't take Enlightenment, then there's one left for someone else. And Rish takes one Health, Healing, and Cure potion each; Alm takes one Healing potion, and Eim takes one Healing potion and one Health potion.
That leaves 2 Healing potions, 4 Cure potions, 3 Health potions, 3 Magic potions, and 5 Energy potions – feel free to take what you need.
There are also 4 Enlightenment potions remaining (5 if no one drinks them), as well as 5 Truth potions – they will stay with me. And if you don't use all the stats, I'll keep the rest in storage.
