Several items, notably the Chaos Trinity and the Raw Steel items, carry the essence of chaos and corruption. Apparently, this has the effect of giving 1 corruption point per turn if carried, and 2 points per turn if equipped. Unfortunately, this effect is so severe, that items with this intrinsic, regardless of how good they may be, are basically never used. Even using these for a short time (eg. clearing the ToEF with the SoRS, carrying the trinity for an ultra) is still enough to inflict significant corruption on the PC, and longterm usage is totally out of the question. For one of these items being equipped, this is almost twice the corruption rate of D:50 in the 1.1.1 days, and, of course, background corruption rates have since been reduced.

My suggestion is that this effect be toned down significantly, to make these items a little more usable. I'd say halving the current corruption rate is probably a good place to start, and even then I think these items would probably still be shunned by the vast majority of players. Going to a quarter of the current rate would probably not be too imbalancing, even.

An alternative might be to have it that these items have increasing corruption with depth, similar to the day 90 effect, but I think that a flat rate is fine, just not at the current levels.
