Test of Faith blinking
While it’s logical that a teleport shouldn’t count as crossing the trap’s threshold, there might be gameplay reasons for it. According to the wiki, the crossing damage is unblockable and it might also be considered logical to apply it regardless of how the enemy escapes. Of course, just to make things more confusing, you can evade the damage via dodging.
Accordingly, I don’t have a strong opinion about whether this should change or not. On my guardian, I like it; on my memser, I don’t.
