What is it with this section of the forums eating up my posts? :(
Okay, here I go again: generally speaking the higher your SL is, the less you get invaded. This is because the game does try to send the invaders to a world of a host whose SL is the closest to the invader's. Darkwraiths can invade anyone above their SL,
Darkmoon anyone below their SL, but those are the only exceptions I'm aware of. That is at least according to what I read when I did research on Darkmoons.
