i did splashing with mind and chaos runes while playing csgo. stun/alch but is quite expensiv but 850k xp/h and normal alch and watched movies.
i bought yew long u or logs and bowstrings and did them to bows on my 2nd acc (now 85+flecht 90+wc) then i alch it. did only 30-50gp lose per alch but this was to slow for me and to click intensiv.
Now alching water runes or maple long u for around 170ea alch is 192 when i get them. Only 1m xp till 94 mage
