Not sure what was going on, but I was in Sphinx 3 and was fighting a Mimic with my knight. I was using an ice pike and only was doing 40 damage with pierce, so I switched to fire, wind, earth, and normal pikes. All did only 40 damage with pierce, and only 20 damage with normal attacks. But earlier on my Sin I was doing normal damage to them with a non elemental jur. Any ideas what was going on?
