The normal version of the mod grants achievements in this way:
theGame.UnlockAchievement( 'ach_spellbreaker' );

it unlocks an achievement based on the name. So it could be possible that you still miss some achievements
after installing this mod due to the fact i need the exact name.

The experimental version works based on a function i found while searching for achievement names. 
It puts all the achievement names in an array so i can just write a short loop to go over all those names
in the array to grant them. that way i don't have to write down 40 ish lines of the same code and i don't
need the names in order for it to work. 
However this is an experimental thing and i cannot verify if it works(cuz i have all achievements)!!
