Alright, these specialization trees work in a pretty specific way. For body builds your key skills are athletics annihilation and street brawler which all sync together for physical combat. The timing on athletics procs is crucial - you'll see a brief yellow glow when stamina bonuses trigger especially during sprints or heavy attacks. For annihilation watch the weapon sway pattern with shotguns, you want to time your shots right as the spread tightens which happens about 0.5 seconds after aiming.

Each attribute branches into specialized skills that work together in combat. When you're running reflexes you've got precise timing windows - handguns have a 0.3 second perfect draw window, blades get critical bonuses during the first 0.8 seconds of combat and assault skills boost mobility for 2 seconds after each reload. The positioning is important here since you want to maintain optimal ranges about 5-7 meters for handguns and 2-3 meters for blade combos.

Intelligence trees are all about hack timing windows, technical focuses on crafting and engineering procs, and cool skills trigger based on stealth states and kill chains. A really effective pattern is combining athletics dodge timing with blade rush attacks - you get a 1.5 second window of increased crit chance right after a perfect dodge. Just remember the skill activation tells are subtle, watch for the quick ui flashes in the bottom right that signal when these timing windows open up.
