tryed it. they don't drop any bones. Then you have to wait for Bork I guess. sigh... ill start to solo bandos after i get the dragon tail bones I can't tank but we could try lootshare bones, because whoever already has one can't get one could make a team of 4-5 people to get one if you'd prefer that.
Kyatts I guess trapped 10 of them, never gave me a bone needs to be something attackable i'm guessing nope i used kyatts killed 20 orks, no bone Femur from those, perhaps something else or has someone actually got one from these?
I agree with you on that and fires runes after, basically after 44 you have alternative of money/xp and when you hit 60s you can move onto other methods.
Regular essence, duel rings and a fire tiara can be great, fire runes this way is a very good way to get a decent runecrafting level, at 44 you could move onto natures, around 100gp profit per essence ;) Hope this helps!
do like 10 loads, calcuate the rune cost the cost of the materials and the profit (take the materials cost from the final glass price), then divide it by 10 basically so you're getting a more realistic sample, maybe even 50 trial loads.
It would be faster to train all seperately but extra money is always nice you could always alternate, you do have some decent money making stats so it's a judgement call for you :)
