That was good, thank you. Got the 'missing' scene with Luthien. Is there anything else new in this? And has anyone encountered Grumpkins at the well? I've checked several times, at different times of day. They never appear.
If you go to the well (and I think it has to be before you start the house quest) and Liandra is not there, then look in the well and proceed from there.
(From the Walkthrough)
Trouble at the well
Activation requirements: No one in party, player at lvl 11 or above, had sex with Liandra, player knows
Summon spell.
If you are asking about the second Grumpkin encounter, I think you have to leave your familiar at the tower, so as to meet the "no one in party" requirement from the first Grumpkin encounter. You should see this when you check the well:
I took me a few tries going back and forth between north forest map and sacred well map for it to trigger. I do not know if there is a higher level requirement, but it triggered for me when my character was at Level 21.
Edit: Ok, it will trigger with the familiar present, and you can get it to trigger if you stand next to the well and repeatedly click on the well until it triggers. If you are having money issues in the game, 99 sacred water sells for 495 coins at Jenny's shop in Weirdwood village.
One last note: It seems to consistently trigger for me when I have drawn water 10 times since the last trigger. My suggestion is to draw as much water as you can carry, sell the water to Jenny, then draw more water until it triggers. There is about ~240 xp worth of enemies down there and the water is 495 gp , so you may wish to use it as an easy xp/gp farm, rather than the permanent solution suggested by the game.
Note that, from what I have seen, you need to actually have inventory space for the water for this to trigger. It has not triggered for me when my inventory was at 99 sacred water, it just gives a message that you can not carry any more water. So make potions or sell water until you can draw water a total of 10 times and that should trigger the event.
