Ser Lucius

Mightiest boss in Leng. Can be found beyond the lairs of Drake and Yportne.

Ser Lucius currently has the most HP of all LoK crits.

Lucius is known to drop the thief Vengeance_Dagger (non-upgraded version), Immortal Str rings (rarely), Cloud Dragon scales, and his Flail (which is arguably the best tank weapon for Knights at this time. Flail is high in defense, low in attack).
