If there isn't at least overloads/turm/pony I would not recommend using a pony. You could also employ a tortoise and enjoy many brews, but Ponies is simpler. Yes, I have all the above gear that you're using, with the exception of OSRS gold those with Claws and Fury (Sold my AGS) I do not have CLS. I have turm, but no pony/overloads. What is the other specification wep? I'm thinking Dragon Halberd To be honest.

Does it make sense to sell DFS in exchange for Claws? I got spare money in my kingdom (like 4M in there ATM) so any other shield besides DFS/Ely/Divine/Chaotic? My inven will comprise 5 brews, Super attack and super power and finally, three super restores and one prayer potion, with the rest being rocktails. I own a tortoise and I will fill with rocktails. Is that good enough for more than 2/3 solo kills? With AGS and original post equipment I scored 2 kills solo (including minions).

The most efficient method is cannon/steel titan/fremboots 4. The order in which they die will depend on whether or not you want the tanking of Supreme or not. The quickest method is to simply alternate between Supreme and Rex in a world of 2k using cannons. You can also move to Prime if you get any time while both Rex and Supreme were dead. or allow titan and cannon (and/or titan) take out Prime. Titan is very precise on Supreme but not as much on Rex. Prim is kind of weak titan although not as well as Supreme.

Ideal gear would be Nex armours and chaotics, surgebox and arc stream when maging for the increased damage and Divine/Elysian/Chaotic/Drag defender for Supreme, depending on whether you're comfortable flashing soul split while Prime is on you or not.

A good portion of cannonballs will be thrown away on Spinolyps which is why many people don't use a cannon, but it does speed it up quite a bit. It will occasionally damage Rex and buy RS gold Supreme too.
