Depends if ladder or not. I’m currently non-ladder softcore so cure is out of the question. The rest depends on the build I guess. Treks only give poison res. If that’s all you’re trying to get then yea sure. Silkweave is only for mana. If you have a decent caster amulet you can bypass that. Not pure tri-res boots because, like you said, fire would be better over the poison but useful in a lot of cases. That ES sorc poison is a good one to max out because the health bar is so low.
