Radius of reveal

The radius of the shadow mission "Arat Berry" reveal is easily large enough to cover the entire of Taillteann, and a good half of Tara.

I don't know what the exact radius for this is, but it's considerably larger than necessary.
All reveal effects work directly on the owner of the doll - And noone else.

Additionally, the magic shields do NOT activate when struck with the corresponding element - They activate randomly after a time has passed with the doll active. (I have not timed this myself)
The shields will reduce the damage of allies' attacks, too. (For example, if she uses Lightning Shield and a partymate attempts to Thunder someone on the other side of you, the thunder must pass through the shield and will be reduced)

1. ...That's just...huge. I think it twarts Demigod's Reveal at r1 for sure. I'd say it's an absurd radius of around 25000, if not more than the standard rendering distance of like...3000~4000(?).
2. I figured it would be owner only
3. Shield random? I was told it's happens when struck. For sure, I was in a party when this was first out and it casted the shield for its owner after a lightning bolt from a Cerberus. Could be coincidence.

They are indeed random - For example, I have had lightning shield activate in Shadow Wizard. After being stuck by firebolt.

Being struck by a bolt does not trigger the shields to materialize. It was most likely coincidence.
