I was wondering how often do GMs give out Epic Boons?
When I had an individual PC hit 20 in my sandbox Wilderlands game, he got EBs for:
1. At BBn-19 he soloed Kainos Warbringer, a CR 25 demigod son of Ares-Bane - hit BBn-20 and my son persuaded me it was so outrageous the PC (not his) should get an EB too.
2. Finally killing Borritt Crowfinger, the (recently turned Lich, CR 21 + minions) BBEG Prince of the Black Sun who'd been the main villain for 7 years of play.
3. Soloing Matriarx, a CR 21 ancient black dragon - though that was a bit of a kerbstomp battle.
I've been looking at how I should give out EBs in my Runelords campaign with a bunch of PCs at 20th likely long before the finale. Soloing a CR 21+, and completing a major quest, seem like two possibilities. I'm not very keen on tracking XP-for-boons, it feels like it should need something, well, 'Epic'.
