Obtain several buffalo steaks (available in the Towne of Rune and Arcane Archipelago) and locate both a spade and pickaxe, take these to Ogre Village and locate the Floral Hut inside the village area, dig and you will uncover a crazed halfling in the room down. Give him a steak and he will give you a token of smashing. Give Flowerkill the token, followed by 20,000 gold. He will give you a hammer, hold and use it to smash flowers, timing can be around 3 to 4 seconds between attempts, you will need at least 7 flowers smashed to win. There is a 15 minute timer between attemps should you fail, expect to have to try in the order of 10+ times for this mark.
Note: Requires you to wear a dragon's tooth on a necklace.
