What you were expecting to happen, and what actually happened?
I was playing in the Arena with the reworked Ghoul, who decreases the ennemy stat. He decreased the Giant Spider’s magic stat, so her summoning should be lower than 15. Yet she still summoned a level 15 creature.
What are the steps to make it happen again?
From what I’ve been told, all summoning is broken in the Arena at the moment, so I don’t know if this is specific to the Giant Spider or not, but decreasing someone’s magic stat has zero effect on summoning.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
