gull dagger

[fogeyman]

ATMA V told me that the Gull dagger can be dropped from almost any monster in the stony field (normal monsters) and that Andy (not first-kill) has low chances compared to these monsters. However, I'm not sure if ATMA is right about this because it seems odd to me that skeletons in the stony field or spike fiends in dark wood would have a higher chance of dropping Gull than Andy. Is ATMA right? If not, who does have the best chance of dropping the Gull?

BTW, I'm talking about the Normal difficulty above.

Thx for helping me out.
