The way I read this trait “After an enemy’s Fozen debuff expires, this creature afflicts it with Snared” I am expecting that after a creature is thawed they should get snared but that never happens in my fights. I am freezing them with a Coldslam Yeti provoking. Here is a fight history showing an Apis Guardian being frozen then acting without Snared being applied. Let me know if there is any additional information that I can provide.
Thanks for the report!
