The rat covenant is the best thing ever.
1. You get to be a dungeon master and laugh at people throwing hello stones to welcome them into your dungeon
2. People don't know how to pvp there because they didn't willing join and don't know what the fuck is going on
3. You get to help Gyrm people kill people, and they are kickass
4. Every other convenent is full of unhonorable bastards who refuse to bow, but as a person who serves a rat, who the fuck is expecting a fair fight
