I ran the LUA files from 1.1 and 1.01 through a diff utility to see everything that changed in them. I found some stuff that isn't listed in the readme. I also filled in exact numbers where the readme is vague.
Honestly, I don't understand everything in there, so I've put question marks next to stuff I don't understand. If any modders out there can clear up those things, I'd be very thankful.
Oh, and if anyone wants to confirm these things with in-game tests, it would help a lot. I'll mark stuff as confirmed as it happens.
Corruption can no longer target ground.
Chaos AC now uses speed fiend ability.
Entangle now only lasts 10 secs (anyone confirm?)
