my lona is a battle whore.... xD... while most of enemies can be easily juiced to death i have a problem with some of them who just can't be catched(i can't)... archers & some speedy hitters. stamina or hp is not a issue, juicing animation speed is.
As
ZedTed mentioned, if you can catch them off guard, great. But if not, you need FOYA-POWAH! heh
Explosive traps (mines) from Lisa are cheap and pack a punch. Since you invest in Lona's constitution, her carry weight also increases so you can lug them around no problem. Another good strategy are traps, the Hunter Training trait precisely. For one trait point you get infinite traps that only cost 3 stamina (to pick up a rock & set it up), and given the 10(15) Survival for Dark Pot & Hitchhiker you aim for, they will do some serious damage. Just lure them suckers in, and watch them get maimed and mutilated with wounds, which also increases the damage of next trap, lowers their attack and speed. One more tip, pick Bloodlust. Given the high damage of both of these, you will commonly get Overkill.
Edit: Or use a companion as a meat shield/aggro tank. Doggy is good since he has no limit, is fast and can be set up to attack just about anything. Just be fast in devouring mankind so he doesn't get overwhelmed xD
Double edit: Nvm the companions, just remembered the're cockblockers lol for good or for worse, they attack the enemy during juicing and interrupt the process.
