Teine

Prestidigitation:

Out of combat, the Slayer manages to create small flames that light candles, torches and bonfires.

Combat:

As a bonus action you send out a burst of flames in a 10 foot cone, all creatures within the area make a Dexterity saving throw. On a failed saving throw the target takes 1d8 fire damage or half damage on a successful save.

Empowered:

You empower your Teine sign, to linger and set a target ablaze. In addition to the original Ka sign's effect the Slayer chooses a target who is in the area of the Teine sign and sets their armor or skin ablaze. The target burns for an extra 1d6 fire damage. This damage occurs every round at the start of their turn for 1d4 rounds. The creature can use an action to put out the flames ending the effect on itself.

Greater Empowered Teine:

You gain the ability to focus the energy of the Teine blast into a fire stream to hit a single target to devastating effect. The range of the fire stream is 30ft. An enemy hit by this stream immediately takes 3d10 fire damage. Roll a percentile die, on a 55 or above, the enemy is set ablaze. If set ablaze, the enemy takes 1d8 fire damage per round for 1d4 rounds. The enemy on their turn can use their action to put out the fire. They will continue to take fire damage every round on their turn until the fire is put out or until the effects of the sign ends.

Mythic Empowered Teine:

When you Empower your Teine sign you can use the sheer heat of your fire to melt armor and reduce defenses. In addition to the effects of the lower levels of this sign, creatures hit by Teine have their armor class lowered by 2 for the next minute. This does not stack.
