This is my tank setup for melee combat which i use during alot of the steel path content and endgame. I highly recommend you check out my [Twin Krohkur] build which i pair with this set up but any weapon will work.

tips:
1. I used an aura forma for flexibility but not needed since you can still perform well with [Energy Siphon] or [Corrosive Projection] saving you 1 forma
2. I recommend the umbra forma because he is incredibly worth the use this frame is ungodly tanky and hard to kill so these umbral mods really make a difference
3. Use any arcanes you want this is just what i prefer run with my set up
4. I am running Naramon for the extra melee passive but use which ever focus you want
5. all you need to use is 2nd and 4th ability to win

Have fun with the build and any recommendations for changes let me know ^_^
