I'm seeing this under the new Faction Boon descriptions, e.g., Rugged Mentor (Horizon Hunters), but not sure what it means or where to find it.
While working with less experienced Pathfinder allies, you provide important insights that keep your less experienced colleagues safe from harm. For any PCs benefiting from a Level Bump and whose levels are lower than yours, you increase the Level Bump’s modifier to saving throws to 2.
Normal A Level Bump increases a PC’s saving throw modifiers by 1.
Special A PC can only benefit from two mentor boons.
If your the lowest level of a tier (so level 1 in a 1-4) and you're playing high tier, you get a level bump, basically a +1 to all d20s, some temp HP, and +1 to your AC.

Can't seem to link directly to the paragraph near the bottom.
