Investiture of Flame

Flames race across your body, shedding bright light in a 30-foot radius and dim light for an additional 30 feet for the spell's duration. The flames don't harm you. Until the spell ends, you gain the following benefits:

You are immune to 🔥 Fire damage and have resistance to ❄️ Cold damage.

Any creature that moves within 5 feet of you for the first time on a turn or ends its turn there takes 🎲1d10 🔥 Fire damage.

You can use your action to create a line of fire 15 feet long and 5 feet wide extending from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 🎲4d8 🔥 Fire damage on a failed save, or half as much damage on a successful one.
