MMOexp: Based on user feedback on Fextralife from AventurineLe's blog

As you can see in the video above The strays in the video appear to be infected. The normal attacks they use work just as they should, however the combinations hit way too often, as evident by the repeated sounds and the rapid bleeding. Even a person with Elden Ring Runes the highest level of vitality and endurance statistics--which regulate the, among other things, the amount of health points and the resistance to bleeding and bleed resistance, respectively - while wearing heavy-duty armor isn't able to last more than a few seconds before bleeding into the next.

Based on user feedback on Fextralife which is a wiki that provides information on Elden Ring as well as various other Souls game, Writheblood Ruins was at some point home to the immortal slime, however I've been unable to locate footage of the adversary in the action. The issue was apparently resolved with the most recent 1.03 patch.

Although Elden Ring has its fair number of bugs, it is part of the normal course. It's not easy to develop even in the most favourable of times. Given the difficulties of the past couple of years, it's an absolute marvel that FromSoftware could release something that ambitious and is still running pretty well for the majority of people. (It's definitely not Cyberpunk 2077). So, just sit back and avoid this particular part of the game for buy Elden Ring Runes now.
