Aquatic Cloak

Aquatic Cloak is a effect in Xenoblade Chronicles and Future Connected. It reduces the range at which aquatic enemies can detect the user.

Overview
Cloak gems are good for sneaking around and trying to get places without being accosted, presumably by enemies too strong to fight (or too numerous to want to deal with). It's somewhat difficult to estimate their effect at the moment, but a decent gem makes a substantial difference in how close the enemy has to be before it can see/hear/sense the user. However, Aquatic Cloak does not work on grounded or flying enemies (they need Earth Cloak or Aerial Cloak).
