Larva

The  is a tiny monster added in the Survivors of the Void expansion.

Skills & Behavior
Any single instance of damage that deals more than 50% of the Larva's total health will stun it and interrupt its attacks or movement.

Primary: Larval Leap
The Larva takes a spinning leap into the air, arcing high before coming down and creating a splash of acid that deals heavy damage. Any impact caused 0.3 seconds after leaping will cause an explosion that deals 320% damage with a proc coefficient of 1.0 in a radius of 7m with no falloff.

The Larva also takes damage equal to 50% of its max health.

The Larva is actually sprinting while leaping, which gives it an impressive 8.0 speed multiplier, instead of the normal 1.45. Along with the fact that Larvae can maintain motion control and steer while in mid air makes them very hard targets to hit.

This skill has a cooldown of 5 seconds.

Behaviors

 * 1) Use primary: the Larva must be within 24m from its target and have line of sight. This behavior will be active for 3 seconds.
 * 2) Strafe sprinting while waiting for primary: the Larva must be within 24m from its target and have line of sight. This behavior will be active for 3 seconds. Combined with the previous behavior, it means that a Larva will only leap every 6 seconds at minimum. However, considering the fact that Larvae can swarm the player, it is very likely there will be multiple leaps to avoid at almost all times.
 * 3) Chase sprinting off nodegraph: the Larva must be within 10m from its target and have line of sight.
 * 4) Chase sprinting: no requirements. This effectively shows that the Larva will always be sprinting, regardless of what it is doing. As such, its base speed of 1.5m/s is misleading and it actually moves at 12m/s.

Tips

 * Larvae may be small, but they spawn in groups, move surprisingly fast, and deal much more damage than their stature would suggest. Without good reaction time or movement items, getting swarmed by Larvae can be a death sentence.
 * However, because Larvae have such low health and their only attack is telegraphed, dealing even a small amount of damage is enough to interrupt the attack and get some breathing room. This still requires a fast reaction (and extra damage output if the Larva is an Elite).

Version History

Trivia

 * There is a bug in multiplayer where, by having a non-host player and the host player die and rejoin in a specific way, a non-host player can start a run as a Larva instead of a Survivor. This occurs because the Larva's internal ID is first in the list of all character IDs, and the game defaults to selecting this first entry when starting a run if a proper Survivor's ID is not chosen for some reason.
 * The leap self-damage is actually 25% of the Larva's max health. However, since the friendly fire damage coefficient for the monster team is 2, the Larva effectively takes 50% of its health as damage. Having items that modify the damage upon hit, such as and  amplifies this self damage. Therefore, a Larva with more than 90% health and 2 Crowbars will die after the first leap.
 * On the other hand, the friendly fire damage coefficient for the player team is 0.5, so a player playing as Larva would only take 12.5% of their health as damage.
