Sun Strike is a Weapon Damage Multiplier (WDM) attack and is the first skill available in the Amazon Bow devotion tree. It has 100% physical-to-fire damage conversion and a relatively low damage-per-second output. The use cases of Sun Strike are typically for off-screening due to it's long range, and killing enemies that are immune to everything except for fire (the fire guy at Kabraxis upgrade).
Sun Strike is also often allocated for it's synergy with wyrmshot. Supermaxing is not absolutely necessary for this purpose as a healthy 20 points will do the trick.
Sun Strike is not very useful in the early game, because Barrage almost always outshines it.
