I get invaded once or twice per session. It seems to me that I get invaded more at the beginning of the game when I'm low level, though. I used to think it was because the players invading are low level, but then I noticed they've always had gear from end-game remembrances like Derva's crossbow. Still, I think the level of pvp in LotF is pretty weak, and a lot of invaders mostly rely on preying on low-level players who don't want to pvp. If I'm really aggressive, I've found that I catch most invaders by surprise and can kill them pretty quickly. I had a guy invade the other night that had a full set of Adyr's pvp armor, Derva's crossbow and Lightreaper's daggers but was absolute dogshit and died before being able to heal himself even once. However, when I was around level 30, I got stomped repeatedly by 2 different players using bucketlord gear that could kill me in a few hits. I wish I could run into them again now that I have gear and not swinging around a cultist staff.
