The final bosses of each Act have had their drops reworked. They now drop both more and better items, so that they can be profitably farmed if desired.
The base life of all Harvest monsters has been reduced by 30-50%, however Harvest machinery now grants monsters around 100% extra increased life on average. The intention here is to keep the Life values of Monsters spawned in Harvest encounters approximately the same as they were before, but significantly lower the life values on the Desecrated versions of these Monsters to bring them into line with other Desecratable Monsters. Please note that Primal Blisterlords and Primal Crushclaws have had their life reduced by a greater percentage as a result of this change.
The "Allies Cannot Die" aura has been removed. To replace this, a new "Benevolent Guardian" Nemesis modifier has been added which causes the Monster with this modifier to apply an Immunity buff to nearby allies for a short duration. If the original Monster is slain, affected allies lose the Immunity buff. Other Monsters that have this Nemesis modifier cannot be given the Immunity buff.
Rare monsters dominated by Sirus have had their Attack, Cast Speed and Movement Speed lowered.
Tzteosh, Hungering Flame no longer uses his Ultimate Molten Strike skill.
The Bull Thorns skill used by Lieutenant of Rage in The Labyrinth and the Crusher of Gladiators in the Racecourse Map has been visually updated and no longer has Damage Reflection.
The Vaal Pyramid and Arcade Map bosses have had their health increased to bring them closer into line with other Map bosses.
Some bosses now ignore damage if the source of that damage has been a very long distance from it for a period of time (essentially, you can’t just shoot them from beyond their pathfinding radius any more).
Enduring Cry used by monsters has been given a cooldown and had its healing amount standardised. It’s less ridiculous now.
