Herb town quest.

idk, ive killed maybe 400 slimes and gotten their card... in fact, while hunting green snails i found 3 blue snail cards and while hunting orange mushrooms i found 3 blue snail cards, 2 spore cards, and a red snail card.

those may be low level cards but ive also gotten both skele cards and seen triples of each... in maybe 5 total hours of leveling in the minidungeon...

just depends on luck. i havent had any at sand rats yet. took me forever at zl. and cold eyes. lorangs suck. eliza, chimera, snowman, tae roon all suck. for me at least.

omg, you are one lucky papaya. im seriously jealous O_O
i killed green snails all the morning (a few hours), got 2 blue snail cards and no green one
