Here's some of them I wish to see:

- Hot'n'Cold spots added to elite/hard clues with opponent that has typeless attacks and hits via protect prayers even if damage is 10-15s instead of only 25-55 level wilderness cause that area is literally huge compared to other areas where you have to search for spot to dig. This also could prove useful as item used here could be used for Dharok users who want to lower their hitpoints level without drinking overload or getting damaged by opponent.

- Teleport scrolls, like the ones in RS3 where you can teleport to perhaps desert areas easier with normal spell book in tact. For example: https://runescape.fandom.com/wiki/Phoenix_Lair_Teleport

- Firelighters as rewards from all tier clues which could make any light fire in colors of those of firelighter.

- Make heraldic item as requirement for clue scrolls as well. Would make Ironman grind for them worthy.

- Pet from clue scrolls, something like https://runescape.fandom.com/wiki/Lava_hawk

Some of ideas sure takes time to be implement but you get the hang of it. Opinions?
