What is your suggestion?:
Add Crystal outcrops to the Super Donator Zone, near gem rocks, as an alternate way to obtain salve shards to make salve amulets (e).

Is this in OSRS?:
Yes, on OSRS you are able to chisel salve shards in the Haunted Mine and create as many salve amulets as you'd like.
Has this suggestion been accepted already?:
No, the last suggestion addressing this topic resulted in the cost of salve amulets being decreased from 25 to 5 slayer points each.
How would this benefit Alora?:
Salve amulets are crucial to have for TOB and some COX layouts. 5 slayer points for every TOB run adds up quickly and salve amulets should be more accessible. Adding some crystal outcrops to the Super Donator Zone would provide a slight buff to that area and some extra incentive to donate.
On OSRS, salve shards can be chiseled from crystal outcrops and then crafted into salve amulets by adding a ball of wool or using the string jewelry lunar spell. On Alora, this process could just create the Salve amulet (e) because Tarn's diary is not in the game to enchant them.
