First Atk Plus

First Atk Plus is a gem effect in Xenoblade Chronicles. It raises the dealt by the user's first  or art in a battle. If this turns out to miss, or is an art that does not deal damage, it still counts as the first attack. If the first attack is a multi-hit move, the damage bonus only applies to the first hit.

Overview
First Attack Plus is fairly inconsequential in long-winded battles such as boss fights, but when fighting through a bunch of spread out weaker foes, it helps clean them up fairly well. Triggering on the first auto-attack or art used means that and  are unlikely to benefit, whereas someone like  will be greatly incentivised to sneak up behind enemies and get them.
