Solitaire (Cinnabar)
This jagged red crystal boosts your resilience when you hit your foes hard.
Power (Encounter): Free Action. Use this power when you score a critical hit on your turn. Roll a saving throw against an effect that a save can end.
Special: You cannot use more than one solitaire in an encounter.

Each time you reach a milestone (see page 259), you gain one additional use of a magic item daily power. This benefit can be used to activate any magic item daily power that you have not already used this day (even if you’ve already used a different daily power from that magic item).
After you take an extended rest, all of your magic item daily powers are renewed, and you start fresh with regard to the number of magic item daily powers you can use per day.

Healing Surge: You begin with one use of the power per day, like a daily power. You can renew this item’s power by taking a standard action to funnel your vitality into the item, spending a healing surge in the process. Spending a healing surge in this way doesn’t restore hit points, and this standard action is separate from the action required to activate the item’s power.
