Rulings

From the Monarch release notes

Piercing Shadow Vise’s ability is continuously checking. If you deal arcane damage after Piercing Shadow Vise is already attacking it will still gain +2. This includes if it is a previous chain link or have already dealt damage. (If Piercing Shadow Vise has already dealt damage, increasing it’s won’t retroactively deal any more damage)
