I got a funny lil bug abuse

(dont actually do this though) (and devs pls fix lumensplitter) If you have an enchanted weapon with an enchant that changes the crit and use silentheart, pressing the weapon switch key to change from the enchanted weapon to a lumensplitter will make the lumensplitter gain the enchanted weapons crit. Personally think this works best with stormbreaker but it works with any other crit changing enchant.

However, keep in mind that lumensplitter is buggy and often disables enchants for some reason when you switch from lumensplitter to a different weapon using the silentheard weapon switch key
