Decided to take my 4/55 OR to Road to Labrynith to test him out against spiked armor. I only used medium, heavy, and special attacks. All of those attacks use his tentacles, meaning he shouldn't take damage from it because they reduce instant passive damage by 100%. As I used special attacks I noticed Red was taking damage from spiked armor despite using tentacle attacks. I'm a fairly new OR player but I think this isn't supposed to happen.
