Osrs Forgotten Brew

Heart is still better. I don't think combat spells should be boostable from a lower. 1 dose of forgotten brew. During my 12 kill trip i ran out to repot but muspah dropped ranging pot and ancient brew and just made forgotten with the essence. Real question is why is.

Forgotten brews are pretty busted, they're the same boost as a normal imbued heart which is a higher dps boost than full ancestral at 99 magic.
