We've killed Sebilite Protector 6 times this week and it's dropped 4 Staff of Battle and 2 Poison Wind Censor, 0 Hardened Clay Bracelet. The Staff is supposed to be the Rare and the Bracelet the Common. Small sample size but still statistically unlikely. Any other guilds on Green had different results?
