Training at Time Temple?

Path of regret 5 and path of oblivion 4/5 seem like good maps. Also, hp might be a barrier, as the last few monsters hit over 4k damage. By the way, does poison weakness even matter for venom?

It seems like it's only the Chief Guards of Oblivion (or whatever they're called - the very last ones) that hit over 4k damage. The ones right before them hit ~3.8k tops, which isn't much more than Skelegons and survivable by even unwashed ranged classes by 13x.
