Ironman verdict

Mystic robe bottom (dark) 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 4 monsters for it.

The lowest-level monster that drops it is Aberrant spectre (level 96), at 1/512, about one in 512 kills. That monster also has the best drop rate we list. The 4 monsters we list with a combat level range from level 96 to 335.

It is worn in the legs slot; its biggest bonuses are +15 magic attack and +15 magic defence.

No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 48,000 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 nets about 47,820 coins.
