Its not important too much but i like that weapon so i need put it to inn hostess. Can u make it storable ?

just use it changue class and you will get it on inn same as kahlees

Ya but i want to use it sometimes so i can't cc 20x in a day.

On Titan server we can't make items storable, only tradable/non-tradable. I am sorry but that is not possible. As Mokzavier already said, the only way to store it in Inn Hostess is to make class change when you are wearing the weapon.
