Hits (also known as hitpoints or health) represent the amount of damage a player can withstand before they die. Hits also have a great influence on the player's combat level. Hits are known as Constitution in RuneScape 2.
To gain Hits experience, a player must kill something with either melee or magic. Ranged does not give you Hits experience. The amount of Hits experience received from killing opponents is different for each opponent, and unlike in RuneScape 2, is unrelated to the opponents' Hits. The amount of Hits experience received is not effected by the stance that the player is fighting in. Controlled, Aggressive, Accurate, and Defensive stances all grant the same amount of experience relative to the player's opponent.
Some players prefer to keep their Hits at a low level by training their Attack skill at the dummies in Varrock, using items to decrease their Attack level. This lets them achieve higher combat stats at a lower level (these are known as "Wined pures"). Like all skills, the maximum amount of hits a player can have at any time is 99. When they reach 0 hits, they die, losing all but their three or one most valuable item(s) (based on Alchemy value), and respawning in Lumbridge.
Fury amulet requires 115 Hits to weild.
