At the core of PoE2’s character system is the passive skill tree. This sprawling network of nodes allows players to enhance attributes, increase damage, boost defenses, or unlock entirely new mechanics. Each class begins at a different point on the tree, but ultimately, the possibilities for specialization are nearly limitless. Planning a path through the tree requires foresight, as inefficient choices early on can hinder progression later. Skilled players often plan their builds around specific keystone nodes, which can drastically alter gameplay by introducing unique mechanics or multipliers.Active skills are equally important in build design. PoE2 uses a gem system where skills are socketed into equipment, allowing players to mix and match abilities with support gems that modify their effects. This flexibility encourages experimentation; for instance, combining a fire-based attack gem with support gems that increase area of effect or critical strike chance can create devastating spells capable of clearing large groups of enemies. Players must carefully consider the interactions between their active skills, support gems, and passive nodes to maximize efficiency and damage output.
