- Prior to Update 11, this skill was called "Amphibious", and increased your swimming speed instead of increasing your Max Magicka. The swimming speed increase was moved to the innate Amphibian skill, and no longer requires the investment of skill points.
- In Update 21, the Max Magicka bonus was changed from a percentage to a flat value, and the resource restoration was reduced slightly. This update also increased the level requirements from 5, 15, and 30 to 25, 35, and 50.
- In Update 29, a Max Stamina bonus was added to the skill.
