seed + spoil?

I know seeding prevents items from dropping, but can you both spoil and seed a mob?

It'd have to be harvest and sweep after you kill it (since sweep disposes of the corspe)

Just wondering before I try creatign a dwarf

yes

you have to sweep then harvest in that order I believe. If you harvest before you sweep the mob will dissapear right away.

actually harvest leaves the corpse for a few seconds, sweep seemed to destroy the corpse

like i said, wasnt sure try it both ways one works.

harvest THEN sweep, as you figured out.
also, if fighting passive mobs, always seed THEN spoil. seed does not aggrivate the mob, and spoil does, so if you seed first you save yourself from roughly one bonk to the head.
edit: if fighting aggressive mobs, same thing. because range of seed > range of spoil, the longer range allows you to start sooner if you seed then spoil a mob running at you than it does to spoil then seed. thus, you avoid one more bonk.
