Show Quest Info

Introduction

Emerton accepted your challenge to fight the Scorpion Lord! It appears that he does not realize that you carry the instrument of his defeat, the Spear of Osiris! Defeat the Scorpion Lord!
(To summon the Scorpion Lord, open your bag and right-click on the Summon Scorpion Lord scroll. If the summon fails, you must wait 1 minute before you can make another attempt.)

NPC Dialog

You challenge my new underling? Very well. I will
take great amusement, perhaps even pleasure, in
watching you die horribly.

Quest Completion

No! How could the Scorpion Lord have been
defeated so easily? You wretch! I'll rip you apart!
Huh? Why do my powers not affect you? Wait!
Where are my powers? Evna, you vicious wench,
what did you do?!
