Foreign player Seki recently posted a video of the three-hour full-length injury-free fast pass "Eldon's Ring of Law" on Youtube. He uses the prisoner class to start the game, adding points to the main intelligence deputy dexterity, and the main weapon is the famous knife Moon Cain.

In the video, he states that his goal is to "achieve speed-through without any damage (including from enemies, traps, fallen damage or poison, etc.)," adding that it took him 130 hours of practice to achieve this goal.
In order to be harmless, he cannot increase his attack power by equipping a trinket like the Red Feather Seven-Edged Sword (which increases attack power when health decreases), so it also has some effect on the time of speed pass.
