Could someone please explain how this happens?

GHOSTING EPIDEMIC!

There are very few blues and even fewer reds who use tracking. In fact, I can only think of two other reds besides myself who use it, in the entire time I've been on this shard. But yeah, it's generally not worth it to try to stick around. There are many many chests on the shard!

That said, I don't ever PK people twice. You got away from me once, I think, so that's why I tried a second time. But besides a few exceptions (the "lord of the flies" guilds of idiots like IL and K^A, guilds/players with stupid names - the Gay and S3X guilds come to mind, and people who talk trash), I'll never attack someone I've previously killed.

Tracking is awesome.

I have a stealth/tracker PK. More of an opportunistic PK due to lack of a mount and he's a blast. I also have 2 other blue chars with tracking (one at 50 and one at 100) and it has come in quite handy.

It just seems odd that someone can appear on the very outside of my viewing area, run directly to the spot I've stealthed to, and throw and exp potion directly where I am standing.
