Was minding my own business sneaking around Qeynos with my 26 Dark Elf Rogue and decided to lay some smack down on a sewer rat...
You backstab a sewer rat for 54 points of damage.
You have slain a sewer rat!
a sewer rat's corpse says '..squeak, squeak..'
Lylanthian says 'How dare you!'
...
You backstab Lylanthian for 29 points of damage.
You have slain Lylanthian!
Your faction standing with Fayguard got worse.
Your faction standing with FelGuard got worse.
You gain experience!!
Lylanthian's corpse says 'My comrades will avenge my death.'
Lo and behold, Lylanthian spawned when I killed the sewer rat freaking me out somewhat... So I start beating on him waiting for other NPCs to join in... No NPCs helped... About 6 guards walked passed during the fight totally oblivious to me smacking this guy.
He dropped a Bead Necklace (standard rubbish loot), Wood Elf Parts (guess he's a wood elf, duh), Long Sword and Axe (Not rusty, not bronze, not fs). This guy must be a real old old mob because most of the mobs that dropped normal weapons without a prefix or rusty, etc were supposed to have been altered to drop the lower value weapons (like fine steel). Other than that, I have no clue what this guy is for.
