Elder Lich's power in New World:

"An Elder Lich was a strong opponent. It would be challenging for a platinum-ranked adventurer, and relatively winnable for a mithril-ranked adventurer. For Greenham’s team, if one disregarded their fatigue, it was an opponent they could easily win against." i.e. lower than 21-23, considering Heavy Masher is solid mythril rank. It may not apply to rare liches who lived hundred(s) of years though.
