#Smash a couple of [[Depraved One]]s off the cliff. You probably won't kill them in one hit, but you'll hit them into the water and give the babies something else to chase. Get two or three in there, then get on the wooden platform and jump to your right. As soon as you hit the swamp, look forward and to the left. You should see a stone pathway leading up to your left and slightly behind you. Run to that as fast as you can. Once you're off the swamp and safely on the stone, keep going. [[Garl Vinland]] is chasing you, but he won't go too far up the pathway, so you can stop here, heal, and use your [[ Widow's Lotus]] if necessary.
===Alternative strategy===
Just follow the path to your left, you will completely avoid the [[ Plague Babies]] and reach [[Garl Vinland]] safely. No need to step into the plague water. Fight him at point 4 on the map
