This is gonna make you loved in the index.
Why? Shock mote!
This little thing shocks through walls, and gives a small stun.
With all the Strenght, your Haste mote is also gonna help those thicc Rhinos get around.
Just remember, if you constantly jump, then you have the drop on them, but if they scratch you, you may die.
I use this build to run High Index, and often have most kills and points turned in, so it's not like you can't pick em up. (PUGs)
I recommend using this weapon: https://overframe.gg/build/1539/fulmin/semi-auto-viralrad-with-variants/
I kills them fast, and I've used it up to the 4th round of Index without problems.
For arcane.... I find those to be personal in many cases, so use what you like, I have been lazy when it comes to Eidolon hunting, thus I have garbage Arcanes.
5 min for a single round of High Index.
