And that's the 4th. Phoenix I haven't seen face to face but you can see him in the help section. He's the monster in the battle slot under one of the topics
Angelo can 2 shot most monsters thanks to mind bending and lava's matk (from the battles I've faced him in atleast) seems to be off the scales. They may not look it but they're pretty tough.
And all servers have dead pvp lol. You aren't alone
