- Author: sinHHHans
This Mod adds a Rideable Slaughterfish Mount in the Imperial City - Waterfront. It is a mount made for water.
When you fast travel to Waterfront, walk straight along the bridge which is in front of you. At the end of that bridge you can see the fish on your left side.
You also get a spell for calling your fish if you need it.
Unzipp the .esp file to \Oblivion\Data\
Delete "sinHHHans' RideableSlaughterFish.esp" from your Oblivion\data folder.
None yet. You may wonder why the fish is also working out of water. This works as designed for a good reason. I made that because otherwise it could stop on the ground, where the water is too shallow for it to swim.
