Right now, you can only transmute items of the same time… but what if for those who try, you could also make your weapons look a bit different?
Not any to any, of course… but, say…
Rifles onto Harpoon guns and Spears (bayonets!)
Rifles onto Hammers (hit ‘em with the stock) and once they’re out, Greataxes/Polearms (again, bayonets)
Torches onto Maces (dual-wield torches!) and Scepters
Scepters onto Maces (because sometimes you just want to smack somebody – also, so those guardians can look like they use the same weapon)
Stuff like that, you dig?
