250k a day without no lifing is gonna be expensive unless you have 10+ range brawlers lol.
For quick exp without hastle, you can get about 170k an hour using red chins at ape atol[faster then mummys] you can get 250k+ exp in about 2 hours, but its gonna cost you around 800k-1mil if red chins are still 500 +
If you have 80+ slayer you could chin nechryles in the chaos tunnels, its less exp then chinning at ape atol however lots of seed drops/rune boots/rune full helms and charms to make up for it, you could always spend your 1st week of scaping in the summer at stealing creation and get about 50 sets of sacred clay range armor, that'd make your range training alot faster / cheaper :laugh:
Or you could do what i did, i camped aviansies, every 1k bars i'd g.e them buy chins go ape atol, when there out back to aviansies untill another 1k bars, sorta quick and shouldn't have to spend any money.
