In Save the World, Impact dictates just how effective a weapon is at staggering a monster.
- Each monster has 'impact tolerance', a hidden health bar that takes impact damage. When that health bar is reduced to zero, the monster is staggered. The health bar then resets. Even if you exceed the value inside the bar the husk will not die.
- Impact determines if a husk is staggered/pushed/frozen/stunned. Impact can stun or knock down husks. A weapon with a high impact can push husks back, a weapon with a mid impact can stun husks.
- Impact Perk on weapons and some Hero Perks increases impact,
Game Mechanics[]
A husks impact tolerance determines if an attack that does a stun, stagger, knockdown (or various other effects) will happen or not. Wall and Floor Launcher traps (as an example) will only send a husk flying if their impact tolerance is exceeded. If you've done impact damage to a husk but haven't broken their limit then they'll just shrug it off and keep walking. Impact (in a way) is fundamentally the value that determines whether you can apply certain crowd control effects to a husk.
Husks have an impact threshold. The higher power the husk the higher the number. Smashers have the highest. When their impact threshold is broken, it will knock back or stun the husk. There is also knock back but epic doesn’t let us see those numbers. The higher the knock back is on a weapon, the farther it will send the husks flying
Here's an example of impact at work. Normally a single launcher trap will not have enough impact to send a Smasher flying (if they haven't taken any impact damage). In this example a wall dynamo deals a little impact damage in preparation. Since impact damage occurred before hand, once the Smasher gets to the Floor Launcher the 'attack' from the launcher (which does no health damage) will exceed the impact tolerance of the Smasher and send it flying.
Weapons[]
Blunt weapons, Hydraulic weapons, shotguns, explosives/launchers and "handcannon" pistols generally have high impact and knockback damage
Spears have less impact but more knockback, and are able to continuously knock down a smasher without it ever getting back up using the heavy attack
Fortunately the higher impact weapons dont knock them back but instead it "staggers" them causing them to flinch very quickly interrupting there next action
Most importantly is that both of these stats do not affect damage at all
