The first invader hit me while I was in the merchant menu! I expected nasty tactics, but dang. We duked it out on the stairs and then he ran off. Then I see him in the open area, with a bag on the ground. He waves and appears to point to it. Now, he smacked me while I was talking with the merchant, so of course I was wary approaching! But he let me grab it, and he cheered. Then he bowed several times, so I bowed back. We had a pretty awkward fight, he kept backstabbing me (I gotta learn to do that!) But somehow with my luck, I won in the end.
Shortly after, I had a second invader, and this time, he didn't attack right away. He bowed and dropped two bags of goodies. This was before I've read the wiki, so I was beginning to think, maybe he's giving me goodies to let him kill me so he gets his souls back, ha ha. He ran to the same open area and signaled for me. Well, I figured he wanted to kill me? So I approached slowly with my shield down, and then he "went home."
TL;DR --Is it common to drop stuff when you invade? (And they were items that made my eyes pop when I used them!) Should I nab that sorta thing right away? Is that rude? Are there signs to understand they want a 1 on 1 or can I summon help?
Thanks! Loving this game, even if I'm still stuck on the Taurus Demon.
