Creatures cannot willingly touch materials that repel them, nor even use tools to manipulate such items. They can, however, create circumstances to move the repellant item. For instance, a ghost might telekinetically shatter a window so a breeze from outside disperses salt.

If a material repels a creature, a line of that material prevents a creature from crossing. For the purpose of blocking flying creatures, the effect of a repulsive line extends as far vertically as the line is long, and if the material is in a ring, it functions as a dome of the ring’s radius.

A character can spend an action to brandish a repellant item, which prevents the repelled creature from approaching within five feet and from making melee attacks against it for one minute. When you use this action, you can make an opposed Charisma check against the creature, and if it fails it must move out of your path if you come within 10 feet of it.

A creature can attempt to overcome this repellent effect, such as by trying to cross a barrier or attack a creature brandishing the item. If it succeeds a DC 20 Wisdom saving throw , it can ignore the repulsion from that particular item – and anything similar within 30 feet – for one hour. If they fail, their turn ends and they cannot try again in that area for a day.

However, if a creature is attacked in any way by a creature protected by a repellant item, it can freely ignore the repellant effect as if it had succeeded its saving throw.
