I’m currently sitting at 33 quest points with just 3 F2P quests left to go: Demon Slayer, Shield of Arrav, and Dragon Slayer. In total, adding those 3 unfinished quests, that should put me at 39 quest points. This matches the F2P QP total from Classic, so no issues, right?
Well, unfortunately, Rune Mysteries exists and gives 1 quest point, which should put the F2P quest total at a nice even 40. Likewise, from extensive wiki browsing on all 3 versions of the live game (Classic, OSRS, and RS3) reveals that the quest points received from completing the F2P quests has never changed (at least, past the point of the introduction of quest points).
Unfortunately, I did not pay the closest attention when completing the quests, so I do not know which quest is short a quest point, however I do know that I am/will be short a quest point.
tl;dr: grrr one of the quests is shorting me a quest point grrrrrrrrr >:C
update for those not on the discord: turns out that the rscwiki is bad at math and i trusted they wouldn’t be bad at math. oops. anyway, post is invalid now, but the rscwiki has now been corrected :3
