I was thinking that at the moment skiller shop is kinda odd, you can use Bossing points as skilling points? That has to change. My following ideas are on pictures (all that what you add or do it in youre favor).
How to obtain skiller points
What skiller shop should have with point prices
Skiller points can be obtained by donateing skilling supplies to chest or NPC (Developer choice)
Skiller shop should consist (skilling supplies, cosmetics, skilling pets)
NB! I know some are in shop already but i mentioned all cosmetics that shoud be in that shop!
Than you for attention, this suggestion took me 2 hours of planning and i tought for players who seek for self proofing wants thes updates. Skilling could be much more enjoyable with rewards that boost things abit. Give a feedback what you think and if somethings dont fit here let me know. Also i know you guys mention that cooking gaunthlets, flowers are in shop for 1 gp, well it can always be removed...
