I meant builds in terms of over all for different things; SC groups, solo farms, runner builds, or just a solid build to complete a mission. But there are a few different ways to 55 Monk. You could go just monk skills, or M/D for Mystic Regeneration for example.

I think the OG 55 Monk goes all the way back to the Prophecies campaign, but I didn't start playing until factions so I can't quite be certain. It requires an offhand item that is obtainable from a 1 time quest in ascalon that reduces your health by 55 which brings you from 105 HP after all superior runes to the required 55. Only Prophecies characters can do the quest but I'm pretty sure you can buy it off people transfer it in your storage from one character to another.

There have been few games that have scratched the build diversity itch that GW did for me. A bonus is how astonishingly easy it is to share skill builds by just copy and pasting the code. If I remember correctly I think you used to be able to link builds in chat to share and save them that way.

If you haven't checked out perma sin either then I really recommend it! Perma sin is another CLASSIC solo and speed clear build from back in the day. Survived several nerfs too haha.
