It doesnt seem to long ago that Killing time was released and the dc of 100 on procs. it was a bit sketchy then but I think they will be close to useless now with the raised saves unfortunetly. I am a bit disturbed by it since it does take a bit of grinding to get them with schisms and such. A good example would be the Soul Stealing proc
On hit, Blackrazor can attempt to steal the Soul of a non-boss monster (DC 100 Phantasmal Killer vs Will negates, no effect vs mobs at 10,000 or more HP)
what will it actually actually work on?
Then we got the
The Crash of the Waves: On Harmful Spellcast, you have a small chance of locking an enemy in a frozen block of ice. DC 100.
and
Legendary Freezing Ice proc (DC 100)
wich are more or less the same. But here you upgrade Leopards chill with a 5% chance to freeze (no save? unsure in all honesty, it seemed to proc more) on each hand if dualwielding, to a ?% chance proc on one hand with a dc of 100(fort save?).
it´s sort of a sidegrade to the leopards chill at that point. leopards might even be better just to keep in offhand for procs if you hit often enough.

there are probably a lot more weapons out there, like the tornado with 90 saves. not sure how it works and if it is a save on each hit though.

I think it is way to early for these weapons to be forgotten. most people have not even gathered materials for one of the schism weapons yet.

Even if these weapons will not get changed, I sugest not making Dc saves on procs in the future. if you want a lower chance for it to proc just lower it. 1 in 20 to have a 1 in 20 chance is kinda low.
