Saradomin brew heals 1,000 life points per sip. It can go over your maximum life points by 15%, however, this boost is temporary. It increases your Defence by 4% + 1 while temporarily draining your Strength, Attack, Magic, and Ranged by 4% + 1. The flask is made by blowing robust glass, requiring 89 Crafting and giving 100 experience. Red sandstone can be mined at Oo'glog and smelted using the Robust glass machine also located at Oo'glog. This is an efficient healing method, in terms of inventory space, as it heals 6,000 life points in one slot, albeit taking a few seconds to consume.
