One of the bigger system-wide changes is an alteration to how conditions work. Freeze, Shock, and Chill are now meant to last for 60ms for every 1% of health damage inflicted, up to a maximum of 50% damage (or 3,000ms). The idea is to reward players for improving duration of conditions and normalize some changes, though it will prevent builds that use low-damage electrical area attacks to inflict Shock. Check out all the details in the official posting.
Path of Exile‘s next major update, The Awakening, is going about as well as testing ever does. The newest patch for the closed beta will wipe out player progress whilst bringing in a great deal of polish for existing areas, meaning that players will need to explore the areas again to get a sense of what’s been changed and will have good reason to do so. Documentation is also available for the design goals within the expansion.
