Non Standard Magic Item/Boon

The Shard of Winter
Level 8 artifact

Honor the Winter Spirits, seek and understand the power in nature's harsh challenge to life.

The Shard of Winter bestows power on anyone willing to enter a pact with it. The pact requires the immediate, permanent expenditure of a healing surge, representing the sacrifice of the supplicant's life source to the power of Winter. In exchange for entering the pact, the supplicant can now make a second use of one daily attack power of level 5 of less. Doing so counts as a use of a daily item power.

As the pact continues, additional powers and/or sacrifices accrue.
