If I win a challenge with Jaqen and a second character but then remove the second character from play before triggering Jaqen, for example via Tyrion Lannister (LoCR) by returning a Clansman to hand to raise claim, can I then trigger Jaqen for winning the claim alone? I'd have thought not, as he didn't WIN the claim alone but I'd like to clarify.
Yes, that works. The "attacking alone" situation was clarified in the official FAQ. https://thronesdb.com/faq#FAQ_7 — Odrl 1164
