Thinking of how much profit you make at the end of a task is not ideal. Because the bottom line is, you'll roughly get the same amount of money from drops whether you cannon or not. think of it as a matter of how much time you will save, and how much money in cballs will it cost to save that time. and maybe consider whether you want melee/ranged xp and what not (I personally don't consider this, but you can) I pretty much cannon everything cannonable Cballs are pretty cheap to start with, and they're currently at some of the lowest prices they've been at in a long long time. They say cannon accuracy is a mapped from the accuracy of the weapon you're currently using. Meaning 1 cannonball shot will save you roughly the same amount of time, whether or not the cannon is firing at 5000 cballs or 1000 cballs per hour. based on this logic, I set up a cannon anywhere I can. One thing to note, is that a cannon his a solid 300 dmg max hit, regardless of what weapons you are wielding. So the higher your max hit, the less worthwhile the cannon becomes. (cannon shots are thought to be a map of your accuracy, so your accuracy *might* not be of relevance) this is helpful, maybe i shouldn't use a cannon then, since im using a rapier with exts and maxed equipment(145 str bonus total)
