Game Feature Updates
Helltides
- Helltides now start on the hour for base game zones and on the 30 minute mark in expansion zones, so a Helltide is always at least active in non-expansion zones.
- Aberrant Cinders no longer reset between Helltides.
Gameplay
- Effects that deal damage over time in a specific area, such as Upheaval’s Trailblazing Variant, now have their duration increased by bonuses to Damage Over Time Duration, such as those granted by Shattered Vow.
- Mount speed has been adjusted to be faster baseline, but benefits less for spurring, such that the maximum speed is only slightly increased.
