On this page you will find a description of the Specialized bronze trophy in Shadow of the Tomb Raider. This achievement is obtained by acquiring all skills in one category.
Lara's skills are divided into three groups -blue, red and green. For this trophy you have to unlock all skills from one of these categories. This is a time-consuming trophy, because you must collect enough development points that are required in unlocking them. But that's not all, because some skills are not available for purchase from the beginning. In the picture above there is an example of one of the blocked skills.
There are two main ways to unlock the skills for purchase. The first is further advancement in the main plot. The game assigns new skills at certain moments of the story.
The second way is to complete Challenge Tombs. One new skill is awarded for completing each tomb.
If you want to speed up the acquisition of this achievement, in addition to advancement in the main story and raids of the tombs, try to allocate skill development points from one of your favorite skills from the very beginning of the game. In the case of the other two, buy only those skills that will help you a lot in the game.
