Mogis’s Devotee

As a devotee of Mogis, you have shown yourself to be a brutal combatant. You can call on Mogis’s favor and cast wrathful smite with this trait. Mogis’s blessing manifest as a blood-red glow around your weapon, causing it to shed dim light in a 5-foot radius until the spell ends. You can cast the spell in this way a number of times equal to your Constitution modifier (minimum of once). You regain all expended uses when you finish a long rest. Constitution is your spellcasting ability for this spell.

(Publishing rules disallow this from being limited to wrathful smite, see SRD vs PHB content, choose the spell from the limited list)
