# Unlike standard items, the token is never seen in the target's/player's inventory. (This essentially makes up for the fact that inventory items cannot be disabled.) This feature can be useful in itself without any script attached. For example, you can tag an actor to see if you have already 'hit' them before. | |||

Here's a very useful example. This token effect allows a merchant to initially have one of a set of items in their inventory for sale the first time you visit.

# Equipping a token on the player will make it appear that the token is equipped and will unequip an item of the same type, even though the item will not show up rendered or in the player's inventory. This can be useful BUT it will produce the usual item-equipped message spam. | # Equipping a token on the player will make it appear that the token is equipped and will unequip an item of the same type, even though the item will not show up rendered or in the player's inventory.
