- Shattered Sun Supplies have a 10% chance to contain a Badge of Justice
- Wretched Fiends and Wretched Devourers each have a 30% chance to drop Mana Remnants for "Arm the Wards." Though this is probably reduced a bit by players who kill the Wretched without having the quest, I think 30% is close to the true drop rate (based on my own observation).
For comparison, I checked WOWDB and Thottbot. WOWDB gave 9.2% for the Badge, which is similar, and 98% (!) on the Mana Remnants, which is clearly wrong. Thottbot says 9% on the Badge, and 27% on the Remnants.
