Aqua Affinity

Aqua Affinity is a helmet enchantment that increases underwater mining rate.

Usage
Normally when the player's head is underwater, mining blocks takes 5 times as long as mining while out of water. Wearing armor with Aqua Affinity causes this penalty to be ignored. All levels have the same effect.

The related but distinct speed decrease for mining while floating is not affected by Aqua Affinity.
