So, OdinShieldRelic IS actually the health relic. That's the character name, which really shouldn't ever show up because... well, you can't click it, and it's not supposed to deal damage.

However, looking at your screenshot, it looks like you died well after you picked up the health relic (based on the blue skull's position north of the relic). Rather, OdinShieldRelic likely just popped up because of some other unrelated issue with death recaps.

Ok, if that's the case, then this definitely needs looking into, because I've seen "OdinShieldRelic" in my death recaps quite frequently, and I've just been assuming that it was the storm shield or Odyns Veil active this whole time.

I see this all the time, i figured the same as halfhearted did

Well this is the OP's thread, and if this issue comes up again he can simply bump it back.

I've seen that a lot in my death recap. However, so far as I could tell that was just poorly named tower damage (and tower hits are currently invisible against champions).
