If everything is on the internet, why didn't you look up the information? You're at as much fault as she is for the lack of knowledge. I point you towards my previous statement.
Decided I would track my ores between each mining level on osrs starting with 63: That iron ore was dropped at the bank in motherlode, much happy. Also got 96 smith at artisan's using my Enrichment aura but missed the screenie.
If you had issues and problems and YOU were unable to find these answers on your own, she likely had the same issues. It's not a problem with her being a "stupid girl" its a problem with you feeling entitled to one thing or another in this friendship/relationship with this person.
I guess I'm just confused on the problem. You need 10 of these shards to claim one reward. That's roughly ten hours. It's not a big deal to just use your better amulet
And I asked why that's a bad thing. The goal of the amulet was to assist players towards achieving requirements for plagues end. The only skill it doesn't help from that list is dg which is easy enough to get from 1 to 75 in a quarter of a year.
This is just my opinion on the most efficient but I would recommend barb fishing at your current level, doing the fish dnd for decent xp and bonus xp outfit
