just uploaded a video of skeletica with 8/8 scorch , that guy's a beast !!!
I have the exact question as Cpm22. How about Stone Skin? I have it at 6/8. Been reluctant to take it to 8/8 since most people are saying scorch is the best. Burned 300 cards no luck (damn). However, some guild mates' skeletica is getting killed because scorch fails to activate.
Watched some of the video skipped ahead to other parts. I am very happy to report that Skektica cannot solo bases in GW even after 50,000 gems spent on traits. Great hero but glad he's not invincible with that setup.
