The point of this build is to spam virulence gain enough stacks for ravenous and spam virulence, it doesn’t matter if you take damage thanks to ravenous health regeneration and infinite energy to use parasitic link and ravenous again and again.
Also, you can use a different aura mod and an exilus if you would like but it would cost a forma too, if you would like to cough that up.

I hope you like this build, kidwithnobrainz
