Combat Skills/Talents are one of the 4 Skill Trees in the Witcher 3: Wild Hunt. These abilities increase your offensive, defensive and crossbow skills. There are 5 branches to this Skill Tree. Each branch has 4 skills and each skill has several ranks, leading to a wide variety of possible builds. You will have access to all Tier 1 Skills from the start of the game, but to be able to get put points into the Tier 2 Combat Skills you will need to spend 8 points in this branch. 20 points will unlock the Tier 3 skills and 30 points will unlock the final Tier.
