I remember reading that cornerstone glyphs aren't a good thing. Well, the new BURNDAYRAZ is pretty much that.
Taking down the 50 death protections as an elf wizard of Mystera (crystall ball prep) didn't required a single potion, just a level 1 monster to hit between every fireball and one mid fight leveling (and a 0 mana LEMMISI for comfort

).
Namtar is also really easy. His third form is the most mana consumming because you have to WEYTWUT before every BURNDAYRAZ to prevent his counter, but his health pool already took a serious hit and he doesn't last long.
It's also really easy to take on +4/+5 gorgon/wraith with burning stacks. It's a bit like having an integrated APHEELSIK, and the ressources used in the process are put to good use with a fast Mystera piety farm.
NB: When I switch from Mystera to JJ, it seems the Refreshment boon doesn't work anymore. Is it a bug ?
