Swamp Squelch

Kill Hydras on the swamp near the Iron City and return to Mikhail Kolchugin.

Ah, you just can't go anywhere without stepping on a hydra! They are especially dangerous at night - they silently crawl up at you... and sink their teeth in your leg!
Listen, I cannot leave my position. Could you please teach those nasty things a lesson? We will pay you generously.

How come there are so many of them here?!

Well done! Thank you so much!
