Add a special class of items - Magical Repeaters . They act like wands in some roguelike game: once clicked in inventory, a magical ray is emitted from current player's location in a direction which player is facing. Fire, Plasma, Energy, Cosmic spell trees have beam spells which can be used in Repeaters, for example.
Let's make them craftable from different kinds of materials and different crystals. After certain number of usages Magical Repeater loses its charge. To "recharge" it player should click on floating crystal or some other specially designated magical object. Magical Repeater also may hold a (hidden) counter of total usages and a value of its "durability". If that counter gets more than value of durability a Repeater breaks and needs to be repaired, disassembled into parts or just discarded.
Why I think this is interesting:
It will give a chance for advancement to people who prefer not to use magic often. Crafters will get new experience. People will not be asking about purpose of those huge magical crystals in city.
