You've remembered correctly: the Sigil is bound to the Shield, and it offsets incoming force. Your sigil is . . . Monstrously strong, though, with a total of 7 force. It'll fade over time down to your Limit unless you actively maintain it.
Good fortune though: you don't need to be right there to maintain it!
