With Murkmire I read that Slaughterfish are getting a 3x damage buff, though this was from another post here, I didn't go looking for it in the patch notes. But regardless taking it as truth I realized this may be my last chance at being able to go where no Mikem has gone before, and finally get to the island every Morrowind fan apparently loves. As a disclaimer, I did this using nothing but movement speed buffs and making my mount jump off very high things. No exploiting.
The process was fairly simple, the journey perilous. My main kitty failed greatly several times, but the fish didn't, they ate well that day. Not sure if fish can digest fur though. After that I found a guide on Youtube and changed tactics. Swim speed! Time to get on my Healer. Using the power of Racials and Rapids the path seemed plausible, however tricky.
My body began to riddle the shoreline. I knew it was possible, but just BARELY. I had to make my movements just right. And after, oh, maybe a dozen more corpses,
Huzzah! I have conquered le fish de slaughter.
Crossing the Sea of Ghosts to Atmora though may be challenging. The island itself of course was empty, save for the few ruins you could see from the main island. But the journey and arrival was worth it, actually made me feel like I accomplished something for once in a long while, even if there wasn't any tangible reward.
