Several of these skills mention Focus, which would be one of the two major things on the Ranger's Job UI



Concentrate historically raised hit rate but works well as a damage boost. Was debating between that or Aim to boost ranged skills but eventually decided on a general buff.
Critical Shot and Poacher's Bane are the biggest skills to time out, as you want to ensure you're using them under Concealment to get an extra boost for the Focus spent.



For AoE skills not included above, the main three-hit combo



Only two-hit until ~lv 74, but basic and simple circle AoEs, though Exploding Bolt, Sonic Shot (based on Sonic Boom from hunter in Tactics A2) and Poacher's Bane all contribute to a bit of diversity in that regard.



For general utility, we also have three abilities



Salve is just a self-heal ability
Dig In is a 60s CD that both lowers damage taken and raises the potency of the Ranger's attacks, so long as the ranger stays still.
Terrain Stride, however, has to do with the last set of Ranger's abilities, inspired by both Geomancer and Elementalist.
