Thank you for continuing to post on this topic. Our QA team has taken a closer look and there seems to be an issue after all. Elemental reflect alone is non-bypassable, but if paired with any other defensive buff, the elemental reflect doesn’t reflect damage at all, just status ailments.
We will change Reflect to be counted as a defensive buff to fix this issue. In the future, reflect can be bypassed just like any other defensive buff.
