respective skills. Players set their own goals and objectives as they play the game. They can train their in-game skills, engage non-player character (NPC) monsters and other players in combat and complete quests at their discretion. Players interact with each other through trading, chatting or by participating in mini-games. Skills There are 28 skills in RuneScape, 17 skills available to free-to-play players and an additional 11 for members, which enable players to perform various activities allowing for interaction with NPCs, the environment and other players. Players gain experience points in a skill when they use it. For example, mining an ore trains the mining skill, and when the player accumulates enough experience points in the skill, their character will "level up". As a skill level rises, the ability to retrieve better raw materials and produce better products increases, as does the experience awarded if the player uses new abilities. The total skill level of a player partly symbolises the player's status in the game and subscribers with a high total level can appear on the high scores. Upon reaching the highest available level in a skill, members may buy a special cape to symbolise their achievement. Some skills, such as woodcutting and fishing, enable the player to collect raw materials that can be processed into usable items for other skills, such as fletching and cooking respectively. The items created can be used by the player or sold to shops and other players. Other skills allow players to kill certain NPCs, build their own houses, move around the map with greater ease, steal from various NPCs, market stalls and chests located in-game, light fires, cook their own food, create their own potions, craft runestones and weapons, plant their own plants, hunt NPC animals, raid dungeons, and summon familiars to assist in combat and training skills. Combat RuneScape features a semi-real-time combat system. Combat is an important aspect of the game, allowing players to defeat monsters to obtain dropped items or to complete quests. A combat level is an indicator of how powerful a player or NPC is in combat. For players, it is determined by applying a mathematical formula to their combat skills. Players engage in combat by clicking on the enemy they want their character to attack and will automatically continue fighting until they kill their opponent, die, or retreat from the fight. Most of the game's weapons are medieval
