Eternal Willpower is one of the best assault rifles you can get in The First Descendant. It's a rare quality, meaning you don't have to grind for hours and can get straight into building it, which makes it even better.

This is our best Eternal Willpower build in The First Descendant.

Eternal Willpower has a base Critical Hit Rate of 20 percent, which is significantly higher than other guns. The Phantom Pain, for example, only has nine percent. Because of this, you should prioritize Critical Hit stats over something like Weak Point Damage.

In general, Weak Point Damage on the Eternal Willpower isn't useful. I found that in most missions critical shots are much more consistent than weak point shots, and in Void Intercept Battles you might want to go with a different primary weapon like the Tamer, which gives you more DPS at the cost of mobility.
