Trait Tree: Solitary Thunder
Rank Needed: 0
After using this skill, you get the Sustaining Bolt buff, which lowers the power costs of all your skills by 5%.
In longer fights it is usually better not to consume your attunement to keep up the buff to critical chance from the set bonus Tale of the Storm. Therefore, try to use this skill only when the Charged buff is up (which removes the attunement cost).
