should i start the dlc before or after killing the fire giant ?

[-Blitz-]

as the titel says i want to know what your opinions are regarding when to start the dlc .
I would say you should only kill the bosses neccesery to enter the dlc (radahn and mohg),
and let the fire giant and maliketh and so on live to see if any dialogue changes or things like that .

Not sure, if the base game is affected that much. But it's surely safe to don't go further. I stopped before morgott and got to mogh via varre. But I do it rather to don't be too overlevelled

Up to you, doesn't really matter as far as we know.

I was curious as if there would be much cross-over with npc/events, myself.

I have 3 character saves, all of which purposely have different 'permanent' events completed in the game.

(keeping bosses alive, finishing npc quests (or not), having good shop/npc rapport (or not))

I even left the giant sleeping Elder Dragon Greyoll alive, on one of my characters.
Just to test if it has any effect on the world of shadows.
