EDIT (11 MAY): I was wrong about skele mage and Spell Echo double cast in the video guide. I did more testing. Skele mages definitely get repeats from Spell Echo and Greater Spell Echo (PoH). So I'm pretty sure Awakened SE will work! I used it in old versions but changed for 3.18. Sorry to everyone :(I think the answer from GGG is not clear: https://www.pathofexile.com/forum/view-thread/3123794

Updated my Skeleton Mages guide for Path of Exile 3.18 Sentinel League. The build guide now has both league starter, endgame builds + animate guardian guide + guide for upgrading from league starter to endgame. Lots of gaming showcase + real DPS testing on Elder (don't trust POB numbers).

I also wanted to make the build more casual friendly, so changed from 2 cluster sets to 1 set to reduce cost. So, this isn't a fully minmaxed build, but it should still have enough DPS.

And a lot of people say that 5L Fleshcrafter is stronger than Tabula, so I added a DPS test for the endgame build with +2 Tabula instead of 6L Fleshcrafter.
