Many believe that after a fight that their chakra and weapons are magically back to normal as if what had happened takes no toll on the character, but that is not how it goes in this forum. In Ninja Legend there are certain requirements to replenish weapons and chakra that was lost during battle.
Weapon Restoration
During a battle you may have used up all of or even some of your kunais, shurikens, paper bombs, or whatever. In that case you can only restore these items by either picking them back up from the ground if they are still intact or you can restock when the character returns back to their village (an RP is not required just return to your village). Obviously if you are already in your village your next topic inside the village you are assumed to have replenished your inventory of weapons. If you lost all your weapons and do not return to your village then you can not RP with the missing items. Note, a Rogue ninja's village is considered Amegakure.
Restoring Chakra
Replenishing a character's chakra is different than restocking their weapon inventory. If a ninja loses chakra in an RP for any reason the ninja must enter a new topic, 4 hours after the RP has ended. Chakra will not be restored if the new topic is a continuation of the previous RP.
Note, if any members are shown purposely ignoring these rulings serious action can be taken against the member.
