If you Use beserker, Have Hazmat+ Absorbant. Hazmat is for poison and absorbent is so you cna take damage completely with your shields. Now, Tickles can give you bleed, so keep your distance, specially in t5. If you have enough worth points for extra armor, I would recommend. I hear people dying all the time to pukepus because they got one Shot by KOR. You can take a hit of a nightmare without dying instantly with armor perks. I also recommend having your own medkit. It sounds like this is alot of worth points but you can have plenty of returns at your own discretion.
