I haven't seen any reports, or anyone posting about this, so let's discuss before making any bug reports.
Currently Nether Protection proc both of enemy spells, and my spells.
Example: If I start to cast Rain of Fire, i will get fire protection. If I cast Drain Soul, i will get shadow protection.
It's really annoying to play with this bugged, alongside minions resilience.
