At what ranged level should I try for the fire cape (using muggi's guide) with ranged pots?

 

 

 

Could 75 work, or should I try for 80?

75 should be fine. Just make sure you have 50+ Pray and enough HP and Defs to last a while. Guthans is what wins the game, you're going to be fighting creature after creature for roughly two hours so you'll need the healy healy of guth

I have 76 defence (raising to 80), 78 hp (raising to 80+), and 59 prayer (raising to 60).

 

 

 

I can't afford guthan's, and muggi's method seems to work great.

 

 

 

Now just to get enough money for veracs helm, ranger, boots, and 2 crystal bows...
