What's your best guess as to what the "Siltbreaker event bonus" will be?

I'm aware there is no way to know until Siltbreaker is released (hopefully soon!) but I figured it'd be fun to try and guess what the bonus might be. I'm thinking it'll just be a particle effect or perhaps an icon next to your character name a bit like the aegis effect but only in the Siltbreaker mode.
