How do you get items to display mana costs

I remember in olden days you could get an item to display a mana cost now I can't seem to do it.

I want a summon that costs mana to use but its an item.

Put the active before passives on the ability list.

it apears an item has to be pawnable to display a mana usage cost. Which totally sucks, as I really rather this item not be pawnable (as selling it is paramount to a memory leak).

Couldn't you have a trigger catch him pwning it and give it back to him? Or is it too late by that point?

no, pawn is to late to be caught,i'd have to remake the item at that point. (its an item drop). I think I'll forgoe the cost on summoning the shop.

Instead I'll just give all the sold items a premium in cost.
