Beads belonging to Java's brothers
Each bead gives you perception +1. If the bonuses from these beads contribute to more than half your total perception score, you get a massive headache and cannot perceive anything until removed.
Found in Asterisk, they have the letters CFPSaaaabcellnooorrrsty on them. 12 of the beads were found in the Witch’s dwelling after the fall of Darkness.
