Awesome. My main character is using Estocs and I'm loving my upgraded Drake's Bell but this will definitely be the last weapon I find for him.
Can you provide any more info on how to find the parts/start the quest process for putting it together?
Quest starts automatically, when you find first piece of this sword (2-nd level of Endless Paths, with large hole to lower levels)
Other parts is sealed besides secret doors etc.
Do you really need spoilers? This is little adventure, do not miss it
Hint - clear level, turn on "speed mode" (D key), toggle sneak (ALT key) and walk around every corner to find hidden walls, doors, switches.
.... truly I can't remember all details, where is each part.
