I just finished Sen's and I've only been invaded twice so far but I have questions about both. The first one (Undead Parish) was a full-on dragon, but I one-hit him with the r1 attack of a +15 Great Scythe buffed with Sunlight Blade. How is that possible if he's within 10% of level 333?
Second one happened right at the fog gate to the Iron Golem. I should mention that the reason I decided to play this round human is so that I can summon all the NPCs at boss fights to see what it's like (Solaire I've summoned a few times before, here and there). So I'm messing with my gear at the fog gate when I get invaded. Had no idea where invaders spawn but figured I had a little time. WRONG! Invader hits me from behind, 2-handed, and only dealt about 300-400 hp damage, one second later Tarkus one-shots him with his greatsword. How could level 300+ be one-shot by an npc?
