Gothic II/Onar's Farm

The Package of Weed
Talk to Cipher (near the forge). It turns out his swampweed has been stolen. Talk to Dar (near the rear of the forge on the way to the chapel). He admits taking it but won't tell you where he sold it unless you beat him up. The package of weed is in a warehouse in Khorinis (beside the boatbuilders' shed); you will need to kill the guard in order to get to the chest containing the package.

This is the same package involved in the militia quest A Package Full of Weed; you can solve both by returning the package to Cipher and telling Lord Andre you threw it into the harbor. You will get less experience from Andre this way, but with the extra experience from returning it to Cipher you will end up with more experience overall.

Rod's Sword
Rod will vote for you if you are strong enough to hold his sword. You need 30 strength to wield it. Once you have the sword, refuse to give it back and beat him up, which is now easy since he is unarmed. He will not vote for you or train you until you return his sword, but in the meantime you may wish to keep it; its low strength requirement and long reach makes it a great two-hander early in the game. You can always give it back later when you need to join the mercenaries.

Black Hide
Talk to Raoul again once you join a guild. Choose provocative answers and he will challenge you to bring the hide of a black troll.

There is only one black troll in the game and it's actually shown on the Khorinis area map. You can either spend five minutes stabbing in the back or you can buy s Shrink monster spell from Zuris on the town's marketplace. Return with the hide and accept Raoul's first offer. If you want to sell the hide to Bosper simply beat up Raoul afterwards.
