The Ember Rod is an item dropped by the Magma Boss.
Before Changelog v0.6 it was the only drop item and drop once per boss.
Now the loot of certain Bosses are depending on the player damage, and Ember Rod are mostly only from the drop of top 3 damage dealer.
- You can actually dissolve the Ember Rod into Blaze Powder. Don't try that or else you won't be able to get it back.
