The latest patch update for Elder Scrolls Online is a big one as it comes with a number of performance improvements and the requirement to reinstall the game client. It also released along the latest dungeons for the Harrowstorm DLC, Icereach and Unhallowed Grave. There are also a number of new collectibles, armor sets, titles and additions.
Elder Scrolls Online Update 25 Harrowstorm Major Changes
Update 25 for Elder Scrolls Online is a little out of the norm as it requires everyone to reinstall the game, but also comes with the good news that you will save a chunk of space on your harddrive as Zenimax have now consolidated a number of duplicate files and older data that is now obsolete.

The entire update is 64.22 GB and will dramatically decrease future patch updates, so that’s good news all round. Once you’re done updating you will also receive a free Crimson Torch Pet in the Crown Store for your troubles. The update is now live for PC players, but console players will also go through the same process on March 10th for Xbox One and Playstation 4.
New Dungeons – Harrowstorm DLC
There are new 4 player dungeons now available with the Harrowstorm DLC in both normal and Veteran difficulty with plenty of news sets to gain including Undaunted Monster Sets. This DLC is available for purchase separately in the crown store or as part of ESO Plus monthly subscription. This introduces the first of the Dark Heart of Skyrim content. Complete the unique achievements be rewarded with a unique body marking, a unique weapon style, several titles and unique housing items.
Icereach
Players will venture strange isle of Icereach across the Seas of Ghosts . Expect to face the Icereach Coven, ruthless witches and face terrible storms that may lead to the loss of longboats as you sale from Northern Wrothgar.

Unhallowed Grave
There is also the dungeon Unhallowed Grave, where soldiers long ago buried something deep in the Bangkorai Garrison. This mysterious item is quite evil and is too dangerous to be left unguarded.

New Item Sets
New items sets gained from these dungeons include 2 Light Armor, 2 Medium Armor, 2 Heavy Armor and 2 Unique Monster Masks, totalling 8 sets. There are also additional Cyrodiil crafted sets that can be made at the stations in town Vlastrus, Cropsford and Bruma.

Combat & Gameplay
Probably one of the significant takeaways from the patch notes for combat and abilities is how block has been updated. The calculation for block by the server for sets and passives that key off block, which should now provide a more accurate transition between actively blocking and not. While the core mechanics of block cancellation hasn’t changed nor has the cost, it will now carry out more of the animation of your previous attack animation, providing hopefully a better gameplay experience.
An issue has also been fixed for when your character could still activate Block even when they had depleted Stamina.
Reduced Morph and Abilities Costs
There has also been a reduction for a number of morph abilities costs for balance changes:
- Necromancer’s Boneyard – Reduced cost of ability and morph from 4950 to 3780.
- Sorceror’s Summon Unstable Familiar –
- Reduced cost of ability and the Summon Volatile Familiar morph from 4500 to 3510.
- Lightning Splash – Reduced cost ability and morph from 3780 to 4950
- Templar – Spear Shards – Reduced cost ability and morph from 4950 to 3780
- Weapon
- Bow – Volley Reduced cost ability and morph from 4600 to 3510
