This build is focused on Duration, allowing more time away from the Reservoirs before a refresh is required.

Note: For missions more on the run use [Fused Reservoir] in the Exilus slot.

[Augur Reach] is an optional replacement for [Augur Secrets], if more Range is deemed useful.

Arcanes are flexible. Pick whatever you think you'll need. [Guardian]+[Umbral Vitality] instead of Fiber gives a bit extra durability, but of course at the cost of an arcane slot that could have been useful for something else, like damage.
