You and allies of your choice within 10 feet of you have Resistance to Cold damage. This is the Ember's Kindled Warmth property from Book Two.

You and allies of your choice within 30 feet of you ignore all Deep Pressure and Killing Cold effects, and have Resistance to Fire and Cold damage. This is the Unbound Warmth property.

Twice per Long Rest, when you would be reduced to 0 Hit Points but not killed outright, you are reduced to 1 Hit Point instead. At the start of your next turn, you regain 40 Hit Points. This property does not function if you die before the start of that turn.

As an action, the Ember burns bright, shedding bright light in a 60-foot radius. A hostile creature that starts its turn in that light must succeed on a DC 20 Wisdom saving throw or have the Frightened condition until the start of its next turn. The effect is at will. A creature that succeeds is immune to this property's fear effect until the Ember's light ends.

Once per Long Rest, as an action, choose one mode: allies of your choice within 60 feet gain Advantage on saving throws for 1 minute, or hostile creatures within 60 feet have Disadvantage on saving throws for 1 minute. The chosen effect requires no concentration.

You always know the Count used by this campaign. This property gives you knowledge of the Count's current value, not its cause, consequences, or future changes.

All previously established properties of the Unbanked Ember remain in effect. Their mechanics are unchanged; consult their established descriptions.
