Eura Village
Reward: Special sheltom "Roitra" that gives +40 Health Points

Head to the Force Master located in Eura Village, or the Skill Master located in Pillai Town, they will both tell you that you must hunt down and destroy 10 of the mighty Iron Fists that reign terror in Heart of Perum. If you manage to survive the fatal blows from the might Iron Fists, go back to the NPC you got the quest from and he will reward you with a sheltom called "Roitra" which gives you an additional 40 Health Points for saving Yura Village from certain destruction.
