Some tips for fellow AF invaders.
1, Go into the game and try to look for the host but stay away from him.
1.5 If the world is seeded jump to step 3
2. See if the host is hosting an arena(not moving), normal ganking(looking for you with others) or just progressing the area
2.5 if the host is doing a normal arena just go and fight.
3. If the host is just progressing, the world is seeded or it's a ganking arena without seeds, go into the room before the lever stairs and wait for the host( the silver knights won't chase you down and the area is good for pvp)
4.By now you either get more AFs to help you or you can fight the host in a clean area or the host just discconects
5.If the host has seeded the world and not moving, just use black crystal and leave because Silver Knights will shred you before you get to him/them.
