Elden Ring Celebrant's Rib-Rake Notes & Tips

• Weapon Skill: Barbaric Roar
• This weapon can be infused with Ashes of War
• Celebrant's Rib-Rake can be upgraded by using Smithing Stones
• Grants 10 Runes on causing damage to enemies, with a short cooldown of approximately 2 seconds. Celebrant's Rib-Rake must be the source of damage for this effect to trigger, and can trigger from Ashes of War such as Hoarfrost Stomp. 
• This Weapons effect may rarely trigger multiple times when striking multiple enemies. When power stancing, both weapons share the same timer and will not normally grant double Runes. However, on the somewhat rare occasion that both weapons deal damage simultaneously (appears to be possibly frame-perfect), they will grant double Runes.
