OOO Shivering Isles

by Kobal, Zamir, and others

==============================

You may know that OOO always has been incomplete: The SI expansion has never been included and no other comparable overhaul of it exists. This mod aims to become just that, and compliment OOO as well as possible.

That means the Isles have now proper expansion character. You better get out of your apprenticeship before you attempt to set a foot there, and to actually finish the main questline, that is probably not enough. Come well prepared and bring enough survivability to deal with the forces of madness.

The mod changes just about everything in the Isles, so I won't mention every single detail, but see below for the list of the most notable changes.

Requires Oblivion Script Extender. Does NOT require OOO.

Completely remade balance and leveling system of items, creatures and NPCs.

Greatly increased encounter variance with new creatures who may also fight each other. Stronger enemies may spawn at lower level, and vice versa.

Many new items, including random and hand placed uniques.

Amber and Madness sets were expanded and fixed; mostly for weaponry, which is now complete and doesn't lack any weapon type found in the sets from vanilla Oblivion. The weaponry of Golden Saints and Dark Seducers was expanded too.

All amber and madness weapons, magical or not, will do 30% extra damage vs ordered enemies, but they get healed by their own weapons.

All clothing and armors that were present in vanilla SI but weren't available can be now obtained as you make your progress through SI's main questline. You can find them in Sheogorath's Palace, among other trophies from your journey.

You can now turn Vitharn Keep into your personal estate, and get your own smith in there to forge weapons and armor from Obelisk Shards, found on e.g. bodies of the Knights of Order.

All areas that were inaccessible during the main quest will become available and free to explore once you complete it. This includes also Pinnacle Rock and Brellach (the strongholds of Aureal and Mazken).

After completing the main quest, you will be able to summon portals to take you from and into Shivering Isles (based on Wrye Shivering).

Rank specific equipment for Zealots and Heretics.

Aureals and Mazkens have a much better appearance now (no more ugly faces) and their disposition towards you will be updating properly as you make your progress through SI's main questline.

Since Shivering Isles features a Knight of the Thorn with a unique shield, a unique model was given to t

💡 Beginner Tips

  • Since the mod doesn't require OOO, you can install it directly, but make sure to place it after any other Shivering Isles mods in your load order to avoid conflicts.
  • Use a mod manager like Wrye Bash or OBMM to handle the files — it'll make uninstalling or updating much easier.
  • Check the mod's comments section on Nexus for user reports on compatibility with other overhauls — that's where you'll find real-world advice.
