Planning your Alchemy perks

Completing the whole Alchemy tree costs 15 of the roughly 80 perk points you get by level 81, so most builds take only the perks they will really use. Start with the perks at the bottom of the tree, then follow the branch that suits your play style up to its top perk.

The highest perks in the tree need a skill of 90 or 100: Experimenter (90), Purity (100).

How to level Alchemy

Every time Alchemy goes up, your character earns experience equal to the new skill level, so a high Alchemy skill also helps you level up quickly. Raising it from 15 to 100 takes about 428,568 skill experience in total. Trainers can take it to 90 for about 120,450 gold, five sessions per character level. Use the skill XP calculator for exact numbers between any two levels.
