Doesn't seeding curb drops anyway? Like, when you seed, less drops happen? I've noticed that whenever I'm in a party w/ a seeder. The drops tend to plummet.
Usually no items drop when you use seeds unless they are alternative seeds who allow normal drops. However Adena drops normaly as do Sealstones in Catas/Necros. Event items were included in this exceptional drop rule in the past and also dropped when mobs were seeded but I cannot confirm if it is this way this time.
Seeds does not affect, quest items, event items, and adena.
that alternate seed type just got an 10% sucsess rate, when it hits you won't get an drop therby you still get 'drops'.
No. Other than the truly crappy seed rate, Alt seeds do not stop drops at all. Even when they land. So the seed can be 'successful' but it will not prevent any normal drops.
