Weapons when hero merging?
Alright, so I have a question on something I've been confused on for a while now.
So, I know that when you merge a 5* unit into a 4* one, all skills are inherited. However, I am under the impression that only some legendary weapons can be inherited onto a 4* version of the same unit. Is this true and if so, can someone give me a list of weapons that can or cannot? (doesn't have to be cohesive, just a good amount of examples)
