For example, A member can "paint" the color of, or paint his bronze armor at lvl 23. Iron at level 31, Steel 42, Mithril at 55, Addy at 62, Rune at 76, Dragon at 84. If they want to, they could pay the same NPC. This would not be only to pay for RuneScape Mobile gold metals. It is also possible to include stripes on your Dragonhide to make it appear more attractive when you take a picture when you kill the first Green Dragon.
So, I considered P2P: Construction lvl. Of 23 to begin on Bronze items at minimum Buying dye/paint and making it. The ability to add stripes is available at lvl. 40 Construction and level at lvl. 40 Crafting. Purchase from NPC at a discounted price.
F2P: You must have armor, and you must have the color of dye. Certain colors are available for purchase at 50k. Some skill lvls. achieved. The armor can vary between 725k and 240k. And its not expensive, but it does put an interesting incentive to buy those lvls and make the profit. I wouldn't be shocked. It's costly because it shouldn't be easy to get. Thoughts and ideas? This is a rough idea. But I was compelled to leave too early to finish the idea.
The idea came out of a search on the suggestion forums. Random dungeons. Throughout runescape, there would be new ways to enter "dungeons" like a cave opening or a trap door etc. Once you enter the dungeon, you will be placed into a starting room with an entrance that leads to the main zone and another one that leads that leads to buy OSRS gold the outside.
