So we know we usually have some etiquette when considering dueling, but when there is no duel and only invasions, what cruel acts do you commit? Or do you ignore your duty as invader and leave?Expecting a duel, I invade and I find myself invading a fellow player (most likely in NG+ or subsequent) with a phantom. This player has proceeded to strike down the Black Knight in the Burg just as I had invaded. Seeing as I don't know what awaits me (I didn't know about the Phantom at the time) I take the risky shortcut and nail it (Like a boss). At the end of the corridor I see the host with his back turned to me, chugging estus. I proceed to follow him with my DGM (A sure 1-shot) and he proceeds to be oblivious of me as he backtracks with his phantom up-front.
They both have Artorias' Greatshields (No way I'm breaking that with any weapon) and are 100% likely to gank me at first sight, but I'm right behind them...and they don't know it. I'm Medium rolling, they might be ninja flipping. They have spears and Greatswords. The odds are not in my favor.
So my inner invader awakens and I instantly backstab kill the host in incredible irony. The poor lad didn't see it coming, then I strike down the phantom mercilessly.
P.S: I felt bad for the guy/girl and messaged them to watch their backs for any sneaky invader utilizing that shortcut. Although I'm not sure I should be giving tips to people already on NG+...
