Omen of Bad Moon - Item Raises Monster Levels

I would like to propose a fun idea to GGG for a new omen that when placed in your inventory would increase monster levels in your instance, thus making them grant additional XP and influences the loot they drop. This gives an option for players and their allies to increase the challenge during a dungeon run, but also yield better rewards. This is a new non-crafting omen and consumed upon use.

Omen of Bad Moon
Drop Level: 1
While this item is active in your inventory, monsters in your instance will be of higher level:
* Normal monsters: +2 levels
* Magic monsters: +3 levels
* Rare and Unique monsters: +5 levels
Note: Right click this item in your inventory to set it to be active. This item is consumed when triggered. Only one omen can be triggered from combat in each instance.
