Ironman verdict

Cadavaberry seed is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 6 monsters and 7 other sources for it.

The lowest-level monster that drops it is Mammoth (level 80), at 20/640, about one in 32 kills. That monster also has the best drop rate we list. The 6 monsters we list with a combat level range from level 80 to 120. It also comes from 7 other sources, such as Master Farmer and Managing Miscellania.

Among the bosses we cover, Obor drops it. It is a reward from these activities: Managing Miscellania and Wise Old Man tasks.

No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 5 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 175 coins; only alch it to clear space.
