HP Up

HP Up is a gem effect in Xenoblade Chronicles and Future Connected. It raises the user's max.

Overview
There are two ways to go about defensive gems: give them to softer characters so they can take a few more hits, or give them to tanks so they can take a lot more hits. In the earlier part of the game, this is mostly a matter of preference. In the later part however, when tanks are starting to reach the hard cap of 9999 HP through other means, the non-tanks become much more attractive users.
