Boss Souls

Boss Souls are dropped by the bosses at the end of every stage.

How To Obtain
When the bosses are defeated their souls are dropped, and added to the counter in the very top left. The BS on Prestige counter is displayed showing the total amount of souls Players have collected this prestige. They do not gain the bonuses of boss souls until they've prestiged.

You can increase the amount of boss souls you obtain by having a Priest in your party, by having the Boss Souls 2x/2x talent and the Pet Talent. Also having the Boss Souls Ring gear. Enchanter further boosts the ring's Boss Souls gain.

Entering the Competition every other day also rewards bonus Boss Souls. Stages have twice the health, but boss grant twice the Boss Souls. You may enter and prestige once you hit 1 second clear time for a generous amount of Boss Souls. Otherwise Players can enter, leave, and enter again once they hit 1 second clear time.

Uses
For every Boss Soul Players collect, they earn a passive 2% to the Damage Bonus. Spending collected boss souls does not deplete this bonus Boss Souls are used to increase Artifact levels and to go on Tavern quests.
