Item spell with no target or charges?

I want to create an item that one can click on to activate a spell without a target (like summon wolf or turn invisible) but I want it to have not have charges (like the dagger of escape) I just want to make the charge number disappear, the item to be used to run a trigger by being clicked on, I have done it before with "inventory buttons but they have charges (so I set the charge number the page number of the inventory slot so it looks ok at added a charge every time it was used) however I would like to get away from that so I can make a button to get to an "equipment screen" and a number on that button would make no scene. If I did not ex plane myself good enough please tell me.

Dagger of escape doesn't have any charges. Anyway, look at some of the miscelanious items, like helm of battlethirst, there are some with activated abilities without targets that have no charges...

This would fit more under general development.

However they requre a target, I want something you click and it imidently casts the spell, thus the no target requred....

I usually base dummy spells off Roar or warstomp.

However I want an Item, not a unit spell, one you click on to activate in your inventory

base it off health stone, set its ability to the one u want, then set charges to 0. i used it with an avatar spell.

You could also use the staff that summons two headhunters. It is found in the Orc RPG Campaign and some point. I am not sure of its exact name but It has no charges, a cooldown, no target, and summons two units near the caster.

Umm. Almost any ability can become an item ability and vice versa. In any case there's a item version of roar.

Charges are solely dependent on the item stats. To make an item actively used but with infinite charges set "perishable" to false, "no. of charges" to 0 and "actively used" to true.

I have used the health stone, thanks to everyone that replied. It is working great.
