Bone Upper

Bone Upper is one of 's physical s in Xenoblade Chronicles. It involves him delivering an uppercut to the chosen enemy, given him 12% Talent Gauge.

Overview
Reyn's auto-attack may build a lot of talent gauge per hit, but the long delay between hits means Bone Upper is always useful to get extra boosts. This is especially so once it reaches higher levels and its effect becomes equal to an auto-attack. Combined with its low cooldown, there is every reason to repeatedly use the punch as soon as it becomes available until Mad Taunt is full. Even if Mad Taunt is full, Bone Upper remains a fast, spammable option with average damage once levelled. Being able to combo into Dive Sobat is almost a bonus.
