Spike (gem)

Spike is a gem effect in Xenoblade Chronicles and Future Connected. It gives the user a counter of unlimited range that does -type. As with enemy counter spikes, being d disables it.

Overview
As a gem that triggers upon getting hit, Spike gems are best placed on armour tanks like, whose game plan is to get hit a lot. A dodge tank like (or any non-tank) is less likely to get much value since they're trying to not get hit. The damage dealt is not much, so it needs to add up over a long time to be worth it.
