Critical Rate Up

Critical Rate Up is a in Xenoblade Chronicles 3. It increases the chance of the affected character's attacks being s.

By default, this buff gives a 25% (not +25 percentage points) bonus to crit rate. This bonus is considered before bonuses that increase crit rate by a flat number of percentage points, so it can be deceptively ineffective if much of a character's crit rate is sourced from these flat bonuses. The buff's strength can be increased using effects such as Swelling Blessing. It lasts for 20 seconds at base, up to 40 seconds with buff-duration-increasing effects.

Critical Rate Up is best for characters with enough crit that a 1.25x boost will make a meaningful difference, but not so much that the resulting crit rate far exceeds 100% and the bonus is wasted. It is naturally most effective in conjunction with effects that increase critical damage, such as Critical Hit Plus.
