[quote]Tried to google it, no luck. Does anyone know how do you complete Truth quest step where you decode map fragment by completing Nightfalls with the handicap of at least 100, as Five of Swords ceased to work with Shadowkeep release? Tried Ordeal yesterday (with Five of Swords handicap just in case), didn't count, that was Adept difficulty though, will try higher one tonight. But so far it seems this was not addressed with Shadowkeep release.[/quote] Can’t you still do the regular nightfall with the card?

You need to do the Weekly Nightfall, not the Ordeal. The Five of Swords has no effect outside of the Weekly Nightfall.
