Whilst its good you are getting monster weaknesses up fast-ish in many ways you are making a major-ish [rooster]-up of things.

 

Many monsters have been split in ways that different levels or locale are no longer the same despite having same combat etc which is not being accounted for in your changes currently.

 

Prime example of this is Aberrant Spectre - you have the weakness as thrown for the only version of this monster.

This is perfectly correct in the slayer tower, however go to Polinivneach Slayer Dungeon and the spectres there are weak to arrows.

 

Basically you guys need to check every location of every monster opposed to just the monster.

We're aware of that, but thanks for the heads-up.
