So, i think they’re similar, but different.
biggest difference: a duralumin compounder can’t access the spiritual realm with their compounding alone
secondly: a duralumin compounder doesn’t have adhesion or anything equivalent
thirdly: a duralumin compounder can only manipulate their own connection, not others
Also, I’d like to bring up that this should prob go in general cosmere discussion. @#1 Taln Fan, could you help with that?
