Sunlight Altar Warping Point - After the Taurus Demon, across the bridge and beyond the threshold that is guarded by the Hellkite Dragon.
Undead Parish Warping Point - Beyond the Berenike Knight, in the structure across the narrow bridge leading from the Undead Parish Church. It is found in the old Undead Church above Andre the Blacksmith.
The portcullis behind the Fang Boar is closed when the player approaches too close to it, which causes the Armored Zombie closest to it to rush behind it and pull the lever. As such, it can be prevented from closing by aggroing this Armored Zombie with a ranged attack, thus preventing it from being there to close the gate.
