Item: Chronographer's Glass

Consumable:

600g Active: Reduce cooldown of all your spells (not summoner spells) by 10 seconds. If used while dead, decreases death timer by 10 seconds. Cooldown: 30 seconds (can only carry max 2. Stacks in one item slot)

The idea was to make items more interactive but also have penalties for spamming abilities. This is obvious potentially OP as sht but by making it consumable you now have to decide how to make the 1k gold worth it. The cooldown on the item is to make it so late game you dont have some fed guy constantly resetting cooldowns of all his/her spells.
