Use Saradomin Brews for tanking if you are using Range Pots. The standard rule for repotting is every 5 minutes. So if you drink a Range pot, then wait 5 minutes, that's the time you should drink another dose. However, if you drink a SARADOMIN BREW at that time, your range level will be knocked down to your normal level, you will get a defense boost that is 2 levels superior to the super defense potion, and you will get an hp boost, which no one can say is bad. Then you simply drink the range pot. I do this all the time during slayer. If I drink a pure set, my attack and strength are at 118. When they are 113, I drink a sara brew. This takes my defense up a lot, gives me 24 hp healing, and puts my attack and str at 99/99. Then I drink another pure set and I am 118 attack and strength again, completely cancelling out the bad effects of the brews. It is a common misconception that you need restores to efficiently use brews. That is incorrect. However, this does require that you either bring at least 1 dose or restore or go the first 5 minutes without using brews. When you first enter the area, your levels will not be running out of the potion boost. At that point, you can either drink the range pot and don't use brews for 5 minutes, or you could drink a brew, then a dose of restore, then a range pot.
