[2023] Accidently used lamps on my skillers hitpoints, what do I do???

Are you sure you tried the minor skill reset option?

From Nastroth:

Let's talk about skill resets. -> One skill of my choice (minor)

The two (major) resets, that also reset content associated with Constitution & Prayer or Defence, are the ones that are no longer available.

From your screenshot, it looks like, assuming your Constitution XP is below 2,745 XP, and you haven't used a minor reset in the last 6 months, a minor reset would qualify.

While you're there, you could also block XP in skills you want to ensure you won't accidentally level. (You'll have to return after 7 days to activate your skill reset, so I'd recommend blocking Constitution in case accidental lampage happens in the meantime.)

I want to block XP from specific skills. -> (choose skill icons you want to block) (Note that specifically for Constitution, you can only block XP from rewards that aren't doubled by bonus XP eg lamps, and not combat.)

Lovely! Glad you were able to request a Constitution reset.

When you activate your reset in a week, you'll be able to lower your XP to an input value. So read Nastroth's confirmation carefully to ensure you agree to lower your Constitution XP to the value you want. It's thrown a couple players who mis-read the instructions, and there's a 6 month cooldown before you can request another minor reset to try again.
