Enfeeble only 1% phys reductions?

it indirectly makes you tankier because monsters deal less damage. but I think curses like enfeeble are in a really bad spot right now, because they're already weaker against bosses by design and bosses already have reduced hex effect on them, so enfeeble and temporal chains are almost useless on bosses. it's better to invest in max res, block, regeneration etc

Delve needs a few things to be tanky, primarily

corpse removal/chaos res, because 95% of deaths are caused by wetas and zombie caustic

spam resistance - primarily recovery on block or a good amount on kill due to how much crap is in there

Nowhere in the game really has as much stuff chipping at you as in delve so old 75/75 block characters with a recovery shield could just cruise wherever they wanted until they got to one shot depth.

The other thing you need is to recognise you can't always blaze a trail in delve, sometimes the path mods will be too disgusting, sometimes you'll need to ignore the cart, throw a flare and get rid of a rare before it comes a problem. Dynamite is actually pretty strong too but the point is dragging a soul eater along the length of a path will always get you killed once you actually stop.

defensive curses are hard to justify in builds currently due to opportunity cost, the effect of enfeeble is actually worth it to selfcast but as a projectile build for example it has to match up against snipers mark lmao, and it can't do that. Alternatively you have to get a source of +1 curse which is a substantial number of passives (more than you'll get back in tankiness from enfeeble) or gearing complications.

Personally aspect of the spider is the only defensive curse i actually use right now :p
