The value of the items is rated based on its rareness and its ability combined with the ammunition to equip the player with weapons. This means that the more valuable the item is, the more rare it is as well as the easier it is used as a weapon to hit other players when combined with the ammunition. The order of the most valuable items is Tiara, Earth Gem, Wind Gem, Fire Gem, and Water Gem.
A player should prioritize attacking another player who acquires the Tiara. This is because there exists only one Tiara in the environment. Therefore, it is the hardest item and yet the most crucial one to obtain in order to win or to prevent other players from winning the game. Earth Gem is good in short distance attack such that other players will be certainly hit if a player is close enough to others. Wind Gem and Fire Gem have a fixed direction onto the target in long distance attack. Water Gem covers a wide target area in long distance attack.
