Not to mention that having to get that assessment against an NPC that isn’t even guaranteed to appear upon using duel orbs is needlessly frustrating. Luna’s unlock mission was annoying yes, but at least I didn’t have to do anything against a specific NPC. And Luna’s character missions are the easiest in the 5Ds world. Crow? He’s a pain to unlock his character missions and complete them.
I can't unlock Luna, I've won 100 duels using Leo, and it didn't trigger the event
Try winning some more duels, maybe you miscounted. I took a note and still miscounted, apparently I forgot to update my note at one point, resulting in Luna appearing faster than I thought it would be.
Also, remember that the 3x multiplier does not multiply wins, it only multiply rewards.
Crow is super easy to unlock. If you don’t have access to yubel or Ra you can simply make a beater deck with spikeshield. Tribute set a summoned skull or something else with a decent attack and defense then let them attack and activate all 3 spike shields and boom easy over 9999 damage plus the rest
I used a Winged Dragon of Ra/Aromage deck to beat it. Just increase your life points as much as you can with Aroma garden, then summon Winged Dragon of Ra and equip with Big Bang Shot and you should be good.
