Boost Stones

Boost Stones are items used to upgrade weapons at the blacksmith. Each boost stone adds 10 Experience to a weapon. They are the only way to upgrade weapons.

Boost Stones can be obtained in a number of ways:
 * Uncommonly spawns as a monster drop.
 * Can spawn around the map as a floating cluster, usually awarding between two and six stones.
 * Can be extracted from Boost Stone Ores in amounts scaling with the ore's health.
 * Can occasionally be awarded from quests.
 * Can be rewarded from Lobby Chest.
