I think Garrett can also be equipped: crossbow, dagger (if possible with the crossbow, otherwise in the inventory), quiver, gems, military uniform, cloak, mermaid, pistol with a bullet. I think something like that, if he comes and corrects it, he will. When moving from one tile to another, Garrett immediately uses stealth in case of an attack by monsters or bandits...
Then Aiko's equipment: staff, mace, hat, cloak, necklace, gems in another slot, bandages x3 in another slot, mermaid in another slot.
Let Kalina take medicines, antitoxin, ice...
Kilika takes a pistol with a bullet, a quiver, and gems in the other slots.
Let her choose the weapon and other slots herself.
Potions of life are given as follows: 1 to Guion, 1 to Aiko, 1 to Beate, 1 to Garrett, 1 to Kilika, all in the inventory, not in the slots.
The remaining items are distributed according to the same principle (if, as I understand it, the whirlpool can wash away both equipped and unequipped items into the sea)
