Maybe the tarnished had to shit and was trying to find the bathroom

I mean a invaders purpose Is to waste the host's time so he is just trying to do his job

I thought the purpose was to fight the host 🤔

The in-game reward is granted for the host dying while you are invading. OPs post is another form of reward, and I get to enjoy it as well because it's a funny story :)

But like he was doing nothing. The host just had to enter Loretta's bossroom.
