Strange Staff

The Strange Staff is a unique epic staff that can be acquired by trading it for 5 Ancient Coins to a Sea Collector.

This staff is unique in that it's secondary attack consumes a large amount of your health to become another staff: the Champion's Staff.

Ability
When the Strange Staff's secondary attack is used, it will consume a large portion of your current health, and transform into the legendary Champion's Staff. This effect will only seemingly occur if it consumes at least 100 Health Points. A message displaying "You feel your life enter the staff." will occur when the transformation is done.

There is no way to revert this effect once it occurs, but seeing as the Champion's Staff is superior to the Strange Staff, there is not much reason to.
