Hey! As said: (And the spoiler below) That character's health that must be some specific number at 175, have a question about that: To make sure I'll be able to repeat the quest more times in order to reach more HP, shall I skip every Adventurer Assignments Quests? Or the HP provided by Adventurer Assignment Quest doesn't count as that base HP?
I used a level 200 character for the questing, my first one when I didnt know anything about hp washing in 2017. The metric was simply noting the time when I pick up the quest and later when I receive the quest rewards and doing simple subtraction. Havent played in years, but pretty sure that Adventurer's Assignment boosted your base hp directly. So you should do Reuel HP quest first until you can no longer repeat it without cooldown and only after that do Olaf and the Ellinia HP quest.
It ok, it doesn't matter. Olaf and elinia quests are not counted torwards the daily cap of the quest.
