So when the player uses it on offense, it works properly. When the player grabs a 4/5 match, it pops up as “Awakened Torment” and all 4 enemies are Cursed/Stunned.
In the gif, I’m playing myself in Test defense in Ancient Khet (it does the same thing in the Guild Wars tab).
I let the AI with my Ossifer grab a 4 match and it pops a regular 3rd Trait Torment and only stunned 1 of my troops. As it can be seen, it’s level 30 and has the upgraded trait.
To be extra thorough, if I grab a 4/5 match on my side of this match the 3rd trait works against the AI and curse/stuns all enemies.
