Idea for a new charm.
Its basically a rework of the Catalyst of Destruction, as it is currently pretty basic, and kind of uninteresting in the current form.
The Catalyst of Destruction would be replaced by a charm called "The Devourer". This charm is actually a living creature/demon with an endless, though sometimes picky appetite.
Similar to the Catalyst of Destruction, it will have the destroy items cube recipe, however any items destroyed in this case are actually fed to The Devourer.
The charm could either drop off of a Super Unique, or have a low chance to drop from regular enemies.
The Devourer doesn't grant you anything extra by default, but the demon can be fed to increase its power which will grant you some benefits as it grows.
1st State: (Level 0 - Hungry)
Name: The Devourer
Orange Text: This strange demon has an endless, yet sometimes picky appetite.
Yellow Text: Cube the demon with items to increase its power.
White Text: Keep in inventory to Gain Bonus
White Text: Required Level: ??
White Text: Power Level: 0
Blue Text: +20 Hungry for Anything
Blue Text: +0 Digested
Feeding The Devourer items will add -1 from Hungry for Anything until it reaches 0. (feed the devourer 20 items, they can be anything)
It will also add +1 to Digested until it reaches 20 (shows how many items it has eaten in total)
2nd State: (Level 0 - Craving)
Name: The Devourer
Orange Text: This strange demon has an endless, yet sometimes picky appetite.
Yellow Text: The demon will no longer eat until it's craving is satisfied.
White Text: Keep in inventory to Gain Bonus
White Text: Required Level: ??
White Text: Power Level: 0
Blue Text: +0 Hungry for Anything
Blue Text: +20 Digested
Red Text: The Devourer hungers for an Arcane Crystal.
The Devourer will no longer eat/destroy items until it is fed an Arcane Crystal.
3rd State: (Level 1 - Hungry)

The Devourer can continue to be fed as normal (in the last example he will only take Magic items to increase progress) until the next threshold, where again he will ask for a certain item to continue progress and unlock the next reward. Rewards can range from being vague (any sword) to being very specific (unique jewel).
The items which provide progress towards the next level may change as The Devourer's power level increases.
It may start out gaining power from any item, but as it gets stronger it will want better and better items, and have much more valuable cravings. (corner stone of the world jewel)
I suggested this to Whist a while back when he was working on whist mod.. but here it is again.
Also, I've stated that the devourer will stop eating until it's cravings are met, but perhaps he can continue eating, it will just halt progression towards it's next power level until the craving is met, at which point it will resume as normal. Extra items fed during the craving period do not count towards power level progress however.
