Ironman verdict
Umbral frag 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 9 monsters and 6 other sources for it.
The lowest-level monster that drops it is Hermit crab (level 19), at 1/1,280, about one in 1,280 kills. The best rate is from Aquanite (level 145): 6/128. The 9 monsters we list with a combat level range from level 19 to 305. It also comes from 6 other sources, such as Rusty chest and Martial salvage.
No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 46 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 134 coins; only alch it to clear space.
