Not a crash. Just a simple spelling error that I thought I would bring to your attention.
In the Reaper description, it says "When applied to a weapon this enchant increases that chance that a mob killed by sad weapon will drop their soul".

It should be: "When applied to a weapon, this enchant increases the chance that a mob will drop their soul" OR "When applied to a weapon, this enchant increases the chance that a mob killed by said weapon will drop their soul".

Not a big priority, but a mistake nonetheless :)
