Lock-On Resist

Lock-On Resist is a gem effect in Xenoblade Chronicles. It adds a percentage chance that the user will not be affected by the debuff.

Overview
Lock-On isn't a very threatening debuff for the party to deal with most of the time. It only becomes a problem if a different enemy does something that warrants immediate attention (such as causing a vision). So in that sense, the characters that most need to resist lock-on are those who can inflict sleep or similar, so they can stop the sideshows and go back to joining their team in the main pummelling. Of course, like most debuff resistance gems, they aren't worth putting on if nothing nearby is capable of inflicting it.
