I don't think I have ever seen this item, and I stumbled over mention of it in some wiki article...
https://runescape.wiki/w/Anachronia_base_camp_enhancer
and I've really got eyes on it because... yes yes I suffered to do slayer the hard/old way, but I'm for it if new players can kinda have it working early where their full slayer helm is made passive on stand at slayer lodge, but new players would need a dinosaur tooth, and those drop from really tough monsters that are really kinda hard to stop and kill thousands of when just an intermediate player.
like... archeology... if you're new, but sponsored by a friend... they can help you make lotd passive really early.
slayer... you can do reaper with them every night, and they can make 99 slayer quick, but... then.... there I am tellin her that 99 to 120 slayer is way way longer and needs that helm, and not to lose that helm, and to go grind for tooth... and man... its a long grind.
so does this drop enhancer thingy really exist? is there a discussion for future ways to even let new players know what kind of shortcut "make passive" things are available? could anachronia base drop enhancer come from treasure hunter as often as... say... a dungeoneering wild card?
I have quit rsof because moderator found comments about darklight bonus damage on demons "off topic" for wildy flash mobs full of demons
