Yeiy! ACW is down...
It was a close call, after getting it severely injured with the slaying ammo, I blinded it with the cursed potion of invisibility and start hitting it, it panicked and got me down to 75HP. I had to use the water orb and gained one corruption but it fell after a couple of more hits.
The corruptions I have so far are not that bad but I am a bit worried that I have no means of corruption removal (the ACW rotted on the way to Terinyo), and of course I am still scared of the Mana Temple and closing the gate... but one step at a time.
Thanks for all the recommendations, as I mentioned before, this is the first time I engaged the ACW in melee... it was really fun
