Make "Water from the Spring of Youth" questline repeatable every 10 levels from lv120+

So what you're saying is HP washing is "optional" but playing with drk is mandatory

 

If this is implemented, i hope that the repeated quests after the initial 5 would include quest items instead of tradeables. Make the quest into a challenge instead of another way for mages to make money. Getting the extra hp should be a difficult thing you go out of your way to get, not an alternative payment option to effortlessly use to skip to endgame HP. Also this will help avoid stuff like hackers farming the items and making their prices unstable and usually cheaper than it should be, considering the effort it takes to farm them (EX: golden teeth).

 

This right here lmao. As long as some players are able to HP wash, DKs will never be plentiful, making washing mandatory. If *no one* is able to wash, in theory DKs would become popular and they would simply become a crucial part of a bossing party such as a bishop or SE, but we all know everyone would just make bloodwashed HB mules anyway.
