Aggressiveness

''See also: Tolerance

Aggressiveness is a term to define how certain monsters in RuneScape behave when adjacant to players. Some are ignorant, meaning they will not attack players unless attacked first, while others will attack other players depending on their combat level as well as the monster's own level. Aggressive monsters can be particularly dangerous when in a multi-combat area with multiple monsters.

Whether a monster will attack a player is determined by the following formula:
 * If $$a <= (b x 2)$$, then the monster is aggressive, where a is the player's combat level and b is the monster's combat level.
 * Otherwise, if $$a > (b x 2)$$ then the monster is tolerant of the player's presence and will not attack him/her.

For example, suppose that a level 51 player wanders into an area with level 30 Hobgoblins. Since in this case that a is less than b x 2 (51 < 30 x 2, 60), the game engine decides that the Hobgoblins will attack the player. Conversely, suppose a level 105 player also wanders into the same area. Since in this case that a is in fact greater than (bx2) (105 > 30 x 2, 60), the Hobgoblins decide to ignore the player (until/unless he/she attacks them first).
