3. Mobility and Crowd Control
For builds that rely heavily on mobility (like kiting builds or speed-based builds), the goal is often to Path of exile currency evade enemies and deal damage at range. However, these builds sometimes lack sufficient crowd control to deal with mobs or bosses that become too aggressive.

Increased Stun Duration can help such builds by slowing down the action and preventing enemies from closing the gap. By stunning enemies for a longer period, you give yourself more time to reposition, evade attacks, or deal damage. It can also buy time for abilities or skills to be used effectively.
Example: A Bow-based Ranger build with high evasion and speed might struggle against bosses that deal large amounts of damage in short bursts. By incorporating Increased Stun Duration into their setup, they can keep the boss stunned for longer periods, reducing the risk of taking high damage and buying time to POE currency buy heal or apply debuffs.
4. Clear Speed and Bossing Builds
For builds that need to be effective at both clear speed and bossing, you need to address two very different challenges. Clear speed is about rapidly clearing hordes of enemies, while bossing requires consistent and efficient damage output.

Increased Stun Duration helps fill the gap between those two aspects by allowing clear speed builds to handle bosses more effectively. By stunning enemies for a longer period, a clear speed build can neutralize tougher mobs or bosses long enough to deal more damage without being interrupted by attacks or mechanics.
Example: A Cleave Champion might excel in clear speed, but struggle against tough bosses. By adding Increased Stun Duration, they can stun the boss during specific phases, providing more time to apply damage over time effects (such as Bleed) or dealing high burst damage without being overwhelmed by the boss’s mechanics.
