There are so many secondary options in Warframe it can be hard to pick a favorite. Among the one that stand out is the Vaykor Marelok. The weapon deals a truck of damage and has a fantastic status chance of thirty five percent but sports a lower critical multiplier of only one point five. The list of drawbacks continue with the rough recoil, low riven disposition and an absurd amount of impact damage. Even with all of these issues the weapon the Vaykor Marelok can pack one hell of a punch when build correctly.
You can go for a straight elemental build or you can attempt a slash build through the use of Maim, of course a negative impact riven would do wonders for the weapon. The idea behind it is to get the impact out of the running for procs.
Overall the Vaykor Marelok is a very strong secondary weapon but has some usability issues as-well, some of these can be easily addressed with mods but others are bit more difficult to get around.
