Saradomin potion

A Saradomin potion is a potion that boosts your Constitution by 12 levels, your Defence by 8 levels, and increases the chance of your enemy hitting a 0 on you by 12%. This potion can also be made at level 90 Herblore. Contrary to popular belief this potion cannot be used with the Zamorak potion.

It is very popular because it boosts your Constitution and Defence by a lot. Since non-members can also use it, its popularity has risen even higher. This potion comes in 4 doses. Since Jagex knew this, they put the Grand Exchange price at 3,000 coins. That still did not deter players though. The potion's boosts will stay for 5 minutes, and then it will slowly fall at 1 level per minute. Many players use this potion on PvP worlds. Players make lots of money out of them because they buy the potion at 3,000 and sell it for 5,000. People are willing to pay outrageous prices for this potion.
