I still have to finish the game.
It's literally the first minute of Pillars 2 - and was in the marketing, so I don't think "Holy Spoilers, Batman!" applies.
Level 13 sounds a bit low to finish the Endless Paths. You might want to save at the end of every level now... just so you don't loose too much progress in the event of stronger opposition.
Note that the quests you get from the communing with the gods in Twin Elms might not be as straight foward as you think. Consider the god you are working with before you comply their directions.
It did sound a lot like a late game spoiler for the first installment.
Also I referred to me being at the 13th level of the path, not being at level 13 myself.
Even then I quicksave basically every five minutes and use a saveslot for all suspicious circumstances (or just reload and create one...), also my reaction to what was after the slope in level 15 was a resounding "NOPE!"
I reloaded the save, got away and did a couple of tasks, got some more info out of Grieving Mother and killed Raedric, AGAIN.
Also got around to enchant some armors and weapons, swap around charms, equipment spells, etc. and went on to Craighold but it seems stupidly combat-heavy so I don't know if go on with that or see if I can do something else.
