Sup here goes a few tips for the black gulch :
A) You can use bombs to destroy poison statues and also to light the black pools on fire , hurting the nasties inside of it. Also you can use emit force to destroy the poison statues.
B) If you are gonna use a bonfire ascetic dont use it on the second bonfire , rather on the first , because the second one respawns area boss (I did this by accident) and does not respawn the previous enemies
C) When farming for large titanites , use the second bonfire to reset stage as it doesnt respawns already destroyed poison statues , unless you die.
Hope this helps duders :D
Oh yeah wouldnt let me choose the dark souls 2 forum :/ so any mod can you please move it there?
