This build is pretty much for much for eidolon hunts and its quite fun but might not be fully practical you could also could do 60 60 mods instead of the normal mods or get rid of secondary merciles. You could also do prime [Heated Charge] if you have it ut yo will have to either [Sacrifice] targeting system to r2 or just use normal [Heated Charge] and have max targeting system though targeting system is near useless
