TSS charm recipe success rate

[Mukkul]

The 12 tradeskill charms from The Serpent's Spite expansion have a reduced or limited success rate for the final step in the kiln for some reason. Even though the trivial is 250, it's showing only 75% chance of success in the combine button at skill 350 instead of the expected 95%+. Which explains my high failure rate making these. Do we want to put a special note in the recipes about this?

Alchemist Charm
Artisan Charm
Baker Charm
Brewer Charm
Fletcher Charm
Jeweler Charm
Mechanic Charm
Potter Charm
Researcher Charm
Smith Charm
Tailor Charm
Toxicologist Charm

I wonder what other recipes out there might have altered success rates?

Since there is no field for success rate and we don't know definitively what's driving this, I'm not inclined to add comments for this, but happy to stick it in the pottery forum for people to be able to see.
