The same for the Floating Hangman: I would like to find and conquer it but I don't want to actually ally with the Pirates. Can I do it? Would that give me exp anyway and maybe a good loot (as I imagine)?
Last I played I had to cooperate with one of the two pirate leader to get it. You might even get the key quest item independantly from the pirates but nothing happens. When I got the ship I was still in Onekaza's good grace as nothing during its hunt forced me to enemy myself with any other factions. I even massacred the pirates afterward.
Also I think I blew up the powder magazine
after getting the Hangman.
2) yeah, that: I want to level up a bit more, because I'm almost going to Ukaizo but I'm still level 17 (almost 18). I know that I can go in Kazuwari or in Harbinger's Watch or start the quest for the mages DLC (it starts AFTER I get an ally, right?). But I do not like enormous dungeons just with fights fights and fights. I would like also something mildly interesting lore-related or with something else. What do you suggest? How long do they take each?
Each DLCs are fairly long and full of fights even if a very few are avoidable. I would say they are 4 to maybe 9 hours each, probably slightly shorter if you rush.
If I recall right, you might have a point of no return
half-way through Beast of Winter, then you must finish the dungeon before being able to get out.
Forgotten Sanctum might have one such point but far far later, at around 90% of the DLC and even then I am not sure.
Beast of Winter and Forgotten Sanctum are the most lore filled, especillay the latter. Those are still big dungeons though, with a good amount of fights. They are not as long as Caed Nua's depths for exemple but have a similar fight density I think.
If you do not like a shitload of combats then avoid Kazuwari because it is mostly focused on that. A quarter of it is text-base events and its last third are optional fights for more loot and challenges. It is not realy a dungeon though and you are free to get the hell out of it during 95% of its duration. I do not know if its theme, and so its lore, would interest you(it's about
some of Galawain's secrets and aspects).
