This is an addon for Deep Mob Learning which lers you configure all the trial affixes, you can disable specific affixes in the config file named deepmobaffixes.cfg.
The mod will search for blacklisted affixes on trial keys and replace them with non-blacklisted ones, if there's not enough affixes to be added back, it would simply skip the process.
This mod won't affect existing trial keys, but only modifies them when a player kills a mob with this mod installed.
