Topple Up

Topple Up is a gem effect in Xenoblade Chronicles. It increases the amount of damage dealt to targets that are toppled.

Overview
If toppling is a large part of the player's strategy, Topple Up is a solid gem to put on any character in the party. However, the extra damage dealt will also contribute extra aggro (if the enemy is not also dazed), which will have to be compensated for.

If the player is not focused on toppling, the gem is much less useful, and indeed does nothing at all if there are no topple arts in the party.
