And bam, another perfect weapon. Helps if you only kill the Lords of the Horde, is my experience so far. It's the last "Stop the Enemy Merger" mission, level 13 I wanna say, down-left one square from the Wind Fish Egg. 4~6 weapons per go, ~2 minutes to run (sometimes less), using Rank III Apothecary potion, Thunder Drum in effect on the map. This mission is definitely looking better and better.
