The skill's dev blog reads like a QoL to-do list that was crammed entirely into one skill

You can craft magic armor and weapons! And then there's a shit ton of new armours and stuff, but then you can also break down existing stuff, oh and you can imbue rings (NMZ), oh and there's new tomes (wintertodt), oh and you can upgrade the rune pouch (Bounty hunter), you can also repair runecrafting pouches! Then here's also an anti poison offhand thing for some reason! And then there's scrolls of redirection because why not even though they're related to construction/Pohs/Magic/NMZ, oh and a new minigame thing!

Like holy fucking shit, by comparison, here's my description of Slayer

You are tasked with slaying certain amounts of monsters. Higher level means more difficult enemies and boss access.

Like a skill should be simple yet important to the game world. Not a duct taped vision board with a bunch of random shit plastered all over it that uses themes from so much conflicting content
