Wall of Fire - Stoic

You summon a precisely controlled wall of supernatural fire, shaped and sustained by your Inner Flame, on a solid surface within range. You can make the wall up to 60 feet long, 20 feet high, and 1 foot thick, or a ringed wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall is opaque and lasts for the duration.

When the wall appears, each creature in its area must make a Dexterity saving throw, taking 5d6 Fire damage on a failed save or half as much damage on a successful one.

One side of the wall, selected by you when you cast this spell, deals 5d6 Fire damage to each creature that ends its turn within 10 feet of that side or inside the wall. A creature takes the same damage when it enters the wall for the first time on a turn or ends its turn there. The other side of the wall deals no damage.

Stoic Restraint. This spell is restrained by your Stoic State, decreasing its damage dice from d8s to d6s. This restraint applies to the damage dealt when the wall first appears and all subsequent damage throughout its duration.

Because Wall of Fire already deals Fire damage, Red Colour Conversion does not change its damage type. Your Stoic State improves your Ranger spell save DC, allowing you to control the wall's destructive energy with greater precision at the cost of raw damage.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 4th. This increase applies to both the initial damage and all subsequent damage dealt by the wall.
