The player can also equip different sets of armor, which impart attack and defensive bonuses. Some weapons and armor include slots that gem decorations can be slotted into which boosts the item's statistics. Various armor pieces give special skill boosts, and if the player can equip a set that boosts a skill past set thresholds, they can gain additional passive bonuses such as full resistance to fire or poison attacks. The player can swap weapons and armor outside of adventuring. To progress in the game, the player is typically required to collect parts of the larger monsters that they are assigned to kill, and using those to forge or upgrade weapons and armor. By being able to take on higher-ranked Guild quests with improved equipment, the player will gain access to a larger array of monster parts and world resources that lead to better equipment they can then craft. In the field, the player has a health and stamina meter, as well as an item pouch with limited space where resources like healing potions, bombs, and materials picked up in the field are stored. Certain materials can be combined to make more potent items, such as stronger healing potions. However, once the item pouch is full, the player must choose to discard or swap out items with new ones. As the player hunts, they will take damage from monsters; if their health drops to zero, they are rescued to a base camp where they can set off again, but after falling for a third time, they are returned to the village without any gains made while they were adventuring. The stamina meter drops after performing most intensive actions like running, dodging, or attacking, but restores when the player otherwise is walking around. When the player's stamina is depleted, the character will be forced to stop for a brief period to catch their breath before they can move, leaving them vulnerable to attack. In addition, the maximum stamina that the player has will drop over time while in the field, though certain items can restore the maximum stamina level. While on free hunts, the player can leave the field and return to the village at any time, keeping any items they have collected; on Quest hunts, failure to complete the mission in time or abandoning the quest foregoes any reward items. Players with both the Nintendo 3DS and Wii U versions are able to transfer their character data back and forth between these units, allowing them to continue to build their character while on either system. "Monster Hunter" on the Wii and Wii U offer an online component where up to 4 players can venture on new quests together, represented by the character traveling to a nearby city harbor port.
