Besides using food and paranoia feat, there is anything more to buff my initiative?
I"m playing in the hardest difficulty for the first time and just need more initiative, against Carnifex.
JKK jacket/infused heartbreaker serpent leather armour both give initiative. JKK is +5, heartbreaker I think depends on quality but it'll be around +4 or +5.
Sea serpent belt gives +3. But you can only get it sometimes, other times Styg says fuck you and the quest to get it isn't available.
Alternatively, forget about initiative and stack mechanical resistance instead. Gloves already have an armour piercing penalty, so riot gear+double tungsten boots+helmet make it easy to hit 95% effective DR against him. He's not so scary when you have 95% DR.
There's a chem called twitch, I think. Gives something like +8 to initiative. I used it a lot during my nimble tank shotgunner character.
Oh, you need Expedition for it though. Not sure if you have that DLC.
Doesn't work for Carnifex, it wears off during the incredibly long intro cutscene. I really hate that cutscene.
