I mentioned this in the post with the people talking about AV dead on remora (Grats to you guys) but i think it went ignored. I just was wondering about a theory. . . .
There are 7 Virtue Weapons
There are 7 sin's he can drop
Also. . . .
There are 7 deadly sin weapons (Gluttony sword, Lust Dagger, Wrath tabar etc. . . )
Again there are also 7 sin's AV can drop
I was thinking initially maybe if you trade these he'll give you a certain sin depending on which you trade him just a random theory i was keeping to myself until recently. . . Anyway hope it benefits someone if it works gl
(Try trading all virtue weapons at once or all 7 sin weapons at once if single doesnt work is another thing as well)
