Hello and welcome to my Cockroach Soldier Extermination guide. This is a Free to Play Guide as I am currently Free to Play, but the techniques can be carried across to Pay to Play, Just swap to the best possible armour and weapons available to you .
Roach Soldiers are probably the most rewarding and profitable thing to kill in the Free to Play game. Although I havent spent much time comparing, I have been assured that they are a lot more profit and help gain more XP then Lesser Demons and because of their relative closeness to Edgeville Bank and the Grand Exchange, they make life easier.
I started killing Roaches when I needed cash because I was down to a set of rune and 200k cash. I've logged all of the trips I've made so you can see how profitable, and unprofitable at times, Roaches can be one run takes me around 20 minutes.
