MMO player spends 3 years on "the absolute worst" challenge, and in a terrifying essay warns against doing it unless "you're a bit of a masochist"

Old School RuneScape is unique among MMOs for too many reasons to list here, but a big one is its variety of account types. You have normal, unrestricted accounts and then multiple versions of Ironmen with special limitations. Ironmen can't trade items at all, Group Ironmen trade items only with their teammates, and Hardcore Ironmen lose their status after a single death. For my money, the most difficult account type would be an Ultimate Ironman since they can't trade or bank items, meaning they carry all their valuables at all times (outside of a few workarounds) in the same 28 inventory slots. 

Unsatisfied with what's already regarded as a brutal game mode, OSRS player Schnoblin decided to max out arguably the most tedious skill in the game in possibly the worst way imaginable for an Ultimate Ironman. It took them three years, and now that they've done it, their advice is withering: "Maybe don't do this." 

As Schnoblin explained in a Reddit post, their goal was simple: get an untrimmed Herblore cape on an Ultimate Ironman. In other words, get 99 Herblore before getting 99 in any other skill. This does indeed sound simple, but moving two tons of sand using only your eyelashes is technically simple.  

Herblore is a difficult skill to train even on a normal Ironman account since it requires mountains of herbs and obscure potion ingredients which can be tough to gather. However, it's known as a special Hell for Ultimate Ironmen since they have such limited storage space for all that stuff. Getting Herblore supplies while deliberately throttling gains in skills which would normally make mixing potions much more efficient is like going for a 500-pound squat and then adding another 10 plates to the bar. 

Schnoblin isn't the
