Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

I found an armor just a few minutes ago that has a spell immunity on it that I've not seen before.
Reading it I'm unsure what it actually means, and how it would function mechanically.

I'm posting it here in the Bug section, since I assume it's a bug at the very least with how it is being displayed.



How is that supposed to be read?

1. Does it only grant immunity to a CL version of that spell
2. Is it indicating the level of the spell it grants immunity for?
3. Is it how many times it will grant immunity?

In this case probably moot as AoE immunities don't work. That said, presumably this could happen worth other spells so should likely have someone take a look. However, the RIG is a lot of code for someone to go look at so might not be worth it to be honest.

The 7 is merely useless, as chad pointed in this case it won't work since it's an AoE spell anyway, but even if it was a single target spell with a number behind you can ignore said number. Probably pointing to a string with unecessary information.
