Spreading your wings and clutching the spear of the Nesstaktor, you launch yourself into the air!

<649/657(98%) 386/783 595/605 19075 4 PM>
Sarux writhes in agony as plague sores erupt from his skin.
Sarux's sickness grazes him.
Sarux shivers and suffers.
Sarux's poison decimates him!
You are hungry.
You are starving!
Your leap keeps you out of the reach of your opponents.

<649/657(98%) 376/783 585/605 19075 5 PM>
Reaching the apex of your leap, you spin and hurl yourself at Sarux!

<649/657(98%) 376/783 585/605 19075 5 PM>
With all your might, you strike Sarux with the spear of the Nesstaktor!
Your downward strike *** DEVASTATES *** Sarux!
Sarux yells 'Help! Someone just jumped on me with something really sharp! Ouch!'
Sarux is covered with bleeding wounds.
