Are we unable to corrupt waystones into getting only positive/safe modifiers?

Before 0.3, there was a small chance that corrupting a waystone would do away with all the negative modifiers and you'd be able to run a juiced map without needing to worry about all the annoying stuff like temporal chains, chilled ground, monster pen, etc. Is this just not a thing anymore at all?

Yeah it's not possible anymore i assume, there are no more "positiv mods"
Positiv are only on top now and related to the negative mods in prefixes and suffixes.
Before it was the prefixe giving positiv iirc and the corruption give a chance at getting only prefixes or suffixes. Both being negative affixes now.
