I went through the crack. Clicked on mug without going any further. Got update. Don't have to kill giant or go on bench. You can jump down onto the roof of the building.
I went through hole, killed giant inside next to hole, moved to table and had to kill giant next to table but when I climbed onto the bench and then onto the table I was unable to click on or use the poision in my inventory on the cup. I have no idea why.
I was in the wrong building, please note the cup needed is located in the building that Spudtop is "NOT" standing in front of. (ofcurse this is said in the quest if you pay attention and read it. unlike me)
Germa Prash has agreed to help Spudtop poison one of his rivals. She wants me to sneak into Karatun Hold, find the mug in the building that Spudtop is farthest from, and apply some poison to it.
Stage 1
I need to poison the mug in Karatun Hold.
Start:
I need to poison the cup in Karatun Hold farthest from Spudtop.
Spudtop has requested a favor of Germa... he would like his rival poisoned!
Take the vial of Giant Poison to Keratun Hold, find a way into the northern building (the building Spudtop is NOT standing in front of!), and poison a tankard you find on the table there.
A mouse hole
Easiest way down is to go to the north side of the camp and jump down onto the roof of the west building. From there, drop down to the west side of the building.
There is a very small (to a Giant) crack in the wall on the west side of the building, at 940,77,-2300 , that will let you into a safe spot in the room. You can click on the mug in third person from the ground to complete your mission.
Short of burning an evac, the best way out is to run along the wall to the ramp, then up the ramp and straight out to the log bridge, as fast as you can. Giants are big, but very slow.
