"As you pull the blade free, it begins to rapidly rust away. The legend was never the blade itself, it was the strength of the heroes who led the way.
That strength has caused the ground to shift, rocks fall, everyone dies."
Gotta be careful with those impossible tasks. I let one of my players roll to convince a Wookie, that he spoke Wookie and to let them go, so of course he rolls a bunch of success (FFG dice are weird) and passes. Now I gotta explain how his character is faking speaking Wookie to a being that only speaks Wookie.
The wookie knows he’s bullshitting him, it’s just funny as hell watching him make stupid noises and watch the rest of the party stare in awe.
… Dude, that’s over a 20% chance of success. You sure you dont want to rethink this? it isnt even as improbable as some saves in normal play.
13.1% if BI is a d6, or 20.7% if they’re past level 5 and it’s a d8. Certainly doable
