70 cold 85 energy for me on a Cu.
Same. Physical > Fire > Energy > Cold > Poison. Energy is a very common Element to be hit with, Cold and Poison are fairly rare in comparison. For the rare mobs that do deal heavy Poison damage (Putrifier), a Najasaurus can tank them effortlessly due to 100 Poison Resist. Even that's not needed though, since my 120 Chiv+AI Triton with 80/80/60/57/88 with Consume Damage can kill a discoed Putrifier no problem (and faster than my AI Naja can).
If you really want high Cold Resist, the Frost Mite is king with 85-95 Cold Resist. They themselves deal 100% Cold Damage, but the 2 slot ones can have insane intensity once reaching 5 slots. All the bells and whistles, with points still left to spare and nothing to spend them on. I spent hours farming over a thousand Frost Mites to get a 2 slot with 85 Cold/50 Poison (lowest) to spawn, luckily with 78.3% Intensity. It's a monster at 5 slots, hits the total Stat/Resist/Regen caps, all the 120 PS, and still has 25 TP left with nothing left to spend it on. I use him on Virtuebane, Stygian Dragon, Rikktor, or Semidar.
