I followed the skills order in the (very useful) spreadsheet in the spoiler - when I got to level 100 Superposition, I didn't have the 50 points in Lightning skills that are needed. This may need a tweak n the guide? HTH
Would I be right in thinking that the idea is to put points in Thunderstone until we get to 50 pts overall?
I'm in the set atm, which has 3s Blink, so teleport isn't a real priority right now since I don't have all the end game pieces yet, so maybe those points could be spent somewhere else for now (Familiar?).
