The Charm of Boost is a charm found inside the Ruins of Camdozaal. It can be activated for 1,000 barronite shards from Ramarno's Shard Exchange.
Lasting for an hour, it adds an additional 5% buff to all activities inside the ruins. For example, having the Charm of Mining unlocked while the Charm of Boost is active gives a 15% increase in the chance of success when mining barronite rocks. This timer does not pause on logout.
The player is notified four times in the chat box about the buff: at less than 5, 2, and 1 minute(s) remaining and again when it has run out. These messages are hidden by the game filter.
