yea, probably somewhat easy to build. throw one and blow it up or set a mine in a hotspot and continue with primary until you need it. could do without the exilus if you have a lot of pickups, which saves you a forma actually.

theres a good chance depending on how you use this you won't be priming with on kill effects much, so id say secondary merciless and [Galvanized Shot] are up to you. could put a bane on it but i [Hate] those. third elemental probably, maybe a dual stat but you wont proc it as much so just a 90.
