<p>What I did to get my achievement is first and most important, memorize the order the colours and my "secret" Is, try to have <strong>3 mutagens left </strong>because if you have 15 of the same colour and 1 diferent different It will be literally imposible impossible to transform that single mutagen</p><p>So once you have 13 mutagens and 3 left just wait until you can transform that 3 at the same time</p>
