Naughty does so much for you, it's practically unfair. Useful in all situations, now for a reduced cost of only 2 forma! Let's [Dig] in:

[Enhanced Vitality], [Repair Kit] and [Synth Fiber] ensure the little guy stays alive even in Steel Path content (I promise), and Primed Regen will keep him up if things get real serious.

Sleeping on [Anti-Grav Array]? It's amazing for [Wisp], [Rhino], [Zephyr], [Ivara], and even [Grendel]. (And for bows, if anybody still uses those...) Not playing one of those 'frames? That's cool; you'll find that jumping higher is just fun!

[Primed Animal Instinct] and [Vacuum] should be obvious! Get that loot.

[Guardian] for shield gating. Oh baby.

[Cordon] is one of the single most useful mods in my arsenal. Group 'em up, take 'em out. Who needs Larva? (I'm sorry, [Nidus Prime]! I'll still play you...)

Finally, you have [Assault Mode]. Confused? Check out my Verglas build. TL;DR, it primes Viral for you and does respectable damage.

VARIANT: If you're playing Railjack, consider swapping Repair Kit for Auto-Omni!
