Asmodeus carries a powerful unique artifact, the Ruby Rod, that allows him to use several powerful offensive and defensive spells. The Rod allows Asmodeus to attack with elemental forces, force his enemies to cower in fear, or cover himself with a field which heals and protects him. It is also a powerful melee weapon that can cause grievous wounds with the merest touch. In the default 4th edition setting, the Ruby Rod is a fragment of the shard of pure evil that created the Abyss, but this origin is not suggested in earlier editions.
