Burning the Windmill:

A step-by-step guide to burning the windmill in Dark Souls II: Scholar of the First Sin, clearing poison from the area and making the next boss fight easier.

Keep going through the next door along, then head over the bridge. Stop when you come to the massive gear, then use it to dodge the archers' arrows while you kill the mage knight. When your opponent's dead, go into the next room along where you'll find a ladder to your left, and a hallway to your right.

Enter the hallway on your right and pull the lever. Now go downstairs and kill the enemy that's lurking over to your right. As soon as you get to the next room along, take a left to loot a Pike from a chest. Once you've picked it up, go back into the room you left a moment ago and head towards the ladder. Two enemies will attack you as you approach it, so kill them before climbing up.

When you get to the top of the ladder, you'll have to kill an enemy. Now pass through the misty door and light the bonfire on the other side. Next, light up one of your torches, go back through the door, then head up the ramp on your right towards the windmill.

Be very careful here so that you don't fall off, then set fire to the windmill with your torch as soon as you get close to it. Doing so drains all of the poison out of this area, and makes the next boss fight much easier as a result.

Make your way up the next set of stairs and take the Black Firebombs, but watch out for the nearby lever. If you step on it, you'll take a lot of damage from the darts that fly towards you. Ignore the ladder in the middle of this area, as well as the outside balcony for now, and instead go to the other side of the area. Here'll you find another enemy, as well as a Manikin Mask. Once you've killed the former and looted the latter, get out onto the balcony.

Also, burning the windmill will remove the poison in Harvest Valley which will make loot collecting A LOT easier.
