Lane Creeps

Lane creeps are a type of creep that automatically moves down the three lanes towards the enemy faction's Ancient. Each and every 30 seconds a new group (the creep wave) spawns for each faction at each of their barracks, but the number in the group and their stats eventually change, as the game progresses. Lane creeps engage any hostile unit nearby, but when left unattended, the opposing creeps end up clashing each other in the lanes on their way towards the enemy base.

Like other creeps, lane creeps are vitally important to a hero's progress because they grant resources, allowing for an advantage over the enemy team. They give experience to nearby enemies when killed – as well as gold to heroes who deal the last hit they take. Allied creeps can also be denied by their team, preventing the enemy from getting their gold bounty, and halving the experience gain from them. To get as many last hits as possible, players often manipulate creep position in the lane by abusing their simple AI, gaining an advantage and disrupting the pace of the battle into their favor. Creep control techniques include disruptively pushing forward into towers, pulling neutral creeps for allied lane creeps to fight, or aggroing enemy melee creeps to change their target.

Lane creeps (while controlled by the AI) are the only units capable of disabling. However, once taken over by a player, a lane creep no longer disables the protection.

Types
There are three types of lane creeps: Melee, Ranged and Siege. Melee creeps spawn in larger numbers and have more health and less attack damage than ranged creeps. Ranged creeps have lower health, but deal more damage per attack to creeps, and are able to attack from a distance. However, their attack type causes them to deal less damage against heroes and buildings. Siege creeps spawn in every tenth wave. They have high health and, unlike other lane creeps, have high magic resistance. They have a long ranged attack which deals significantly more damage against buildings. They also prioritize buildings over other units when in range.

Destroying either of the enemy team's melee or ranged barracks causes the destroying team's respective lane to begin spawning super creeps instead of regular creeps. Super creeps are stronger versions of regular lane creeps that give less gold and experience to the enemy when killed. When all enemy barracks are destroyed, mega creeps begin to spawn from all lanes and siege creeps gain additional damage.

Spawning
Lane creeps spawn the first time as the game timer reaches 00:00, right after the game horn sounds. After that, they spawn every 30 seconds. Unlike melee and ranged creeps, siege creeps start spawning on the eleventh wave, and then every tenth wave. This means siege creeps spawn every 5 minutes, with the first ones spawning at 5:00.
 * Spawn timing

Initially, a creep wave consists of 3 melee creeps and 1 ranged creep (and 1 siege creep every 10th wave). As the game progresses, their quantity gets upgraded:
 * 31st wave and onwards (15:00): All lanes get +1 melee creep. Total count of melee creeps is now 4 for all lanes.
 * 61st wave and onwards (30:00): All lanes get +1 melee creep. Total count of melee creeps is now 5 for all lanes.
 * 71st wave and onwards (35:00): All lanes get +1 siege creep. Total count of siege creeps is now 2 for all lanes.
 * 81st wave and onwards (40:00): All lanes get +1 ranged creep. Total count of ranged creeps is now 2 for all lanes.
 * 91st wave and onwards (45:00): All lanes get +1 melee creep. Total count of melee creeps is now 6 for all lanes.

After the 45th minute, a creep wave consists of 6 melee creeps and 2 ranged creeps (and 2 siege creeps every 10th wave), resulting in a total of 8 (10 with siege creeps) creeps per wave.

Lane creeps spawn close to the lanes' barracks. There is however some minor adjustment for each lane, so that they meet at certain points of each lane if they are not interrupted or distracted.
 * Spawn locations

The spawn locations do not change throughout the entire match. The creeps spawn so that the ranged creeps are always behind the melee creeps. However, the siege creeps spawn between the melee creeps.

Stats
Every minutes and  seconds, melee and ranged creeps gain a permanent upgrade to their health and attack damage, as well as an increase to their bounties. The following bonuses are applied:
 * Melee creeps: + health, + attack damage, + gold bounty
 * Ranged creeps: + health, + attack damage, + gold bounty, + experience bounty
 * Super melee creeps: + health, + attack damage, + gold bounty
 * Super ranged creeps: + health, + attack damage, + gold bounty
 * Mega melee creeps: + gold bounty
 * Mega ranged creeps: + gold bounty

These health and damage upgrades are applied a maximum of times, while the gold and experience bounty upgrades have no limit. This means their health and damage are fully upgraded at :0 in-game time, which is hours and  minutes. The total values on each upgrade cycle can be seen in the following table.

Siege creeps only gain one upgrade, and that is + damage upon destroying their respective lane's ranged barracks.

Mega creeps do not grow stronger, but have their bounties increased over time.


 * Melee creeps:
 * When fully upgraded, regular melee creeps have almost as much health as super melee creeps with 11 upgrades.
 * When fully upgraded, regular melee creeps have almost as much attack damage as super melee creeps with 6 upgrades.
 * After upgrades, super melee creeps' gold bounty exceeds that of regular melee creeps with the same amount of upgrades.


 * Ranged creeps:
 * When fully upgraded, regular ranged creeps have a bit more health than super ranged creeps with 10 upgrades.
 * When fully upgraded, regular ranged creeps have as much attack damage as super ranged creeps with 13 upgrades.
 * After upgrades, super ranged creeps have about the same gold bounty as regular ranged creeps with 26 upgrades.

When fully upgraded, super creeps are as exactly as strong as mega creeps, but this does not automatically make them mega creeps. All barracks must be destroyed to get mega creeps. But at this point, the only difference between super and mega creeps is their visual appearance.

Bounties
When a lane creep gets denied by one of its allies, it grants 50% of its experience value to enemies. Enemies may only get full experience when the creep dies to them, or when a neutral creep kills it. Gold bounties are only granted to the enemy player who gets the last hit on the creep.

Behavior
Lane creeps have a set path from which they do not deviate normally. The creeps walk down the lane aggressively, meaning they attack any enemy which comes within their acquisition range, similar to how player-controlled units act when giving them an attack-ground order. If a lane creep gets aggroed and the aggroing unit stays within the creep's acquisition range, it chases the aggroing unit until it is dead, or until it lost track of it, or until another enemy gets within range and draws the aggro off. If the aggroing enemy entered the fog of war, the lane creep walks up to the last spot it saw the enemy. If it then does not see the enemy again, it returns to the point at which it left the lane it belongs to. If the aggroing unit is outside of the lane creep's acquisition range, it chases the enemy for up to 2.3 seconds before returning to its lane. A creep which is no longer aggroed does not join other lanes even if they are closer. It returns to its own lane, even if it is the furthest away.

Drawing Aggro
Aggroed lane creeps follow regular auto-attack rules, meaning they prioritize the closest enemies. So if a unit draws aggro and another unit is closer to them, the closer unit gets attacked, and not the unit which actually aggroed them. If multiple heroes are about equally close, the one which attacks them get prioritized, while the one which does not attack, or attacks an enemy from the opposing faction has second priority, and the one who attacks its own allies has least priority. For the creeps, it does not matter whether the attack actually happens or not, and it also does not matter how far away the target of the attack order is. The attack order alone is enough to aggro or de-aggro them, as long as the creeps are within acquisition range of the aggroing hero. This means issuing an attack command on allied heroes de-aggroes them, while issuing an attack command on enemy heroes aggroes them. However, this behavior has a cooldown of 3 seconds, means they can only be aggroed and de-aggroed this way every 3 seconds. Multiple non-hero units within about equal range have all the same priority, regardless of what they do. The creeps ignore units which attack them from further away, despite them being a bigger threat. They always prioritize closer units. Siege creeps always have a lower priority than heroes and other units, regardless of what they do. Buildings have a lower priority than siege creeps and wards have a lower priority than buildings, also regardless of what they do. If a lane creep attacks one of those 3 unit types, and another creep or hero gets within attack range, the lane creep switches to attack that enemy. Only enemy units within the lane creep's acquisition range are considered by this aggro system, which is range for melee creeps,  range for ranged creeps and  range for siege creeps. It is possible to attack enemies without drawing aggro of nearby enemy lane creeps. This is doable by manually casting active attack modifier on enemies, referred to as orb walking, or by attacking the enemy while not within the creeps' acquisition range.

Siege creeps follow the same aggro system, except that buildings are their highest priority, and enemy siege creeps their second highest. This means if an enemy building is within the siege creep's attack range, the creep immediately switches away from its current target and starts attacking the building. The siege creep prioritizes attacking buildings over other buildings, so a tower is more likely to get attacked than, for example, an effigy building if both are within range.

Until the game clock reaches 5:00, lane creeps cannot be aggroed by player units, unless the lane creeps have enemy lane creeps, or neutral creeps within their acquisition range, or they are within 1500 range of their tier 1 tower. After that, lane creeps can be aggroed by player units unconditionally.

Disarming
If a lane creep is disarmed, it stops moving and stands still until the disarm expires. It completely ignores everything in this state. This prevents the creep from walking past towers if disarmed while at a tower.

Death
Upon dying to a player-controlled unit, lane creeps are knocked up to 200 range away from the damage source, in an arc with up to 50 range upwards. The distance and height get higher, based on the damage instance that killed them (capped at 500), but are still randomised, so that equal damage instances do not result in always the same distances. The knockback duration ranges between 0.4 and 0.6 seconds. Damage below 100 does not cause a knockback. The knockback itself is mainly for aesthetic purposes, but might also affect some abilities. For example, and  follows the corpse of the unit with their effects.

Despite what the death animation of siege creep suggests, siege creeps are knocked back as well. This is because their death animation stays where the unit initially died, and does not follow the unit's actual location.

The knockback does not happen when the creeps are killed by units not controlled by any player.
