• FIRST BIG TIP i can give > after 3-4 runs u will fly like a butterfly and be an expert in finding wisps
• SECOND BIG TIP i can give > farm only at night since more wisps spawn then

This build will let u teleport for a long distance with Wormhole (Skill 3) trough plains to fast travel from lake to lake to check are there any Cetus Wisps

Location of Wisps on Plains of Eidolon (google Cetus [Wisp] map)

If u googled Cetus [Wisp] map or clicked link above u will see few images with routes and in most cases they are the best u just need to develop ur route regardless of that there are no bad routes
Run with ur map open to see if near any lakes are some wisps

This build as u see can be achieved with 0 forma
However i link my Slow Nova and Speed Nova builds which will be interchangeable with each other and this build (for this one i just trow extra [Cunning Drift] into exilus)
