Thanks! The 2 things that were confusing me in the wiki were that the Xis rune and all the enhanced runes include a comma in their bonus descriptions. So I thought maybe it signified they added together. And like I said before the wiki has that statement saying Xis runes can’t be used alone (without explicitly saying “when creating runewords”).
Good to know. I think I’ll acquire Xis runes faster than Shaad runes (if I ever get any)
