Diablo 2 Resurrected Update 1.21 Patch Notes

Terror zones

To unlock the Terror Zones feature, you must defeat Baal per character, per difficulty using any expansion character—existing characters that have already fulfilled the requirements will automatically have this feature unlocked. Once Ladder Season Two begins, players will need to meet the aforementioned requirements to unlock Terror Zones for their new ladder characters.

Here are the level details for each monster type per difficulty:

Normal

• Base: +2 levels up to level 45
• Champion: +4 levels up to level 47
• Unique: +5 levels up to level 48

Ladder season two

Ladder Season Two will begin on October 6, ushering in a new opportunity for brave heroes to race to level 99 and amass powerful loot along the way. This will also be the first Ladder Season with Terror Zones! Can you handle the increased ferocity of the Burning Hells, or will you perish under their amplified might? We cannot wait to see how Terror Zones will influence the leaderboard, or hopefully, allow new players the opportunity to see their name on it for the first time.

New sundering charms

In Hell difficulty, many monsters receive resistance to specific damage types. If their resistance increases above 100%, that monster is then immune to a specific damage type. Because there are only a handful of ways to reduce a monster’s immunity, only a minute portion of hero builds can successfully farm all zones in Diablo II: Resurrected.

Any abilities granted by a Sundering Charm will also extend to your pets and summons, so keep that in mind as you upgrade your character.

The Black Cleft

• Monster Magic Immunity if Sundered
• Magic Resist –45% to -65%

The Bone Break

• Monster Physical Immunity is Sundered
• Physical Damage Received Increased by 10% to 30%

The Cold Rupture

• Monster Cold Immunity is Sundered
• Cold Resist –70% to -90%

The Crack of the Heavens

• Monster Lightning Immunity is Sundered
• Lightning Resist –70% to -90%

The Flame Rift

• Monster Fire Immunity is Sundered
• Fire Resist –70% to -90%

The Rotting Fissure

• Monster Poison Immunity is Sundered
• Poison Resist –70% to -90%
