Never used a Dragonkin Lamp on slayer :) At the moment I'm just collecting them till I've maxed my bank and then I'll decide on what I will do with them ;)
The reason it's been a while since I've posted is that my last post I had to get 3+ posts deleted due to comments that weren't fit on any topics. As for droptab, sold most of it when I reached 70m, all I got left is my 40 odd abyssal whips due to me refusing to sell for less than 1.5M lol
