Iām actually Wizard1 > Pyro1 > Linker1 > Thauma3
Iāll take Pyro for rank 7 and Iāll have to chose btween Sage or Enchanter, it depends if IMC update Enchanter which needs much more attributes. Going Thauma3 is not a bad choice but not the best choice in my opinion, their ultimate skill is not amazing, doesnāt last long enough and has a really expensive attribute. The only good thing when you go Thauma3 is the time of your Left and Right hand buff, mostly the Right buff because it last 50 seconds at lvl 5 and has 50 seconds of CD. The other good thing about Thauma3 is if in my case you donāt use Token to share golds between characters and you are really poor to the fact you still have Cafrisun set at lvl 200, the Right hand buff lvl 10 with a Shield helps a lot for playing solo.
I donā think youāll need Linker3 neither Pyro3, so itās up to you.
Now Iāll just leave this video here of LittleSamson who did a really good build in my opinion (itās your title path) :
Edit : And as you can see most of the time heās dealing so many damages, even additional hits from Linker2 are useless against bosses.
