Skills in PoE2 are highly modular, with gems that can be socketed into gear to grant active abilities. These gems can be leveled and modified with support gems to create powerful combinations. For instance, a fire-based attack skill can be enhanced with support gems that increase damage over time, critical strike chance, or area of effect. Choosing the right combination of skill gems and support gems requires understanding the synergies between them and aligning them with the passive tree. This ensures that every point invested contributes meaningfully to the build’s overall effectiveness.Defensive considerations are equally important. Endgame content in PoE2 often involves encounters with high-damage enemies and unpredictable mechanics. Players must allocate passive points to enhance life, energy shield, resistances, and evasion to survive. Many builds also rely on mobility skills to avoid damage, such as teleports, dashes, or movement-boosting buffs. Balancing offense and defense ensures that players can sustain through difficult encounters while maintaining high damage output.
