Stats

Stats are a core game mechanic in Diep.io. Along with customizing the class of a tank, players can also edit their tank's Stats to master their own play style. This is done by spending the Skill Points earned as a tank levels up. For every Level until 28, tanks gain 1 Skill Point. Once past Level 28, one is obtained at level 30, and one skill point every 3 Levels until hitting Level 45, maxing out at 33 skill points. A stat can be upgraded 7 times before maxing it out. For examples of how Stats can enhance different tank classes for certain play styles, see Builds.

Stats and Their Effects
Health Regen: short for health regeneration, is normal for any tank to regenerate lost health if it has not taken any damage for a given set of time(30 seconds at 0 ranks). More points invested in health regeneration will shorten the time it takes to activate regenerate health but only if you haven't taken damage for a given period of time. Max points in Health regeneration will make it seem like regeneration starts a second or 2 after taking damage. Regeneration is by percentage health increasing maximum health will not slow down the rate of reaching full health.

Max Health: Max Health determines the maximum health pool of your tank. It is evident that having a higher score will increase your size(therefore health bar too) and level. With the more score you have and the more skill investment in the stat, having more health will make your tank bigger. So you gain about 1 max hp upgrade every 6 level. In a rammer vs rammer situation you want to take note of these 2 things: Is your opponent bigger than you by a large margin? Does he have more hit points than you currently? If the answer is yes to any of these then just run because you will clearly lose head on. The game doesn't give exact numbers (save for Motherships), but players are very susceptible to damage early on. Some players invest in this stat early as a survival tactic.

Body Damage: This stat determines how much damage a tank will inflict upon another object on collision. This stat will also lessen damage from bullets this is determined by how much damage it can give to a bullet's health(penetration) so that the bullet will die faster before reaching maximum number of collisions; While many players do not use this as their main method of attack, some Destroyer techniques involve hurling themselves at opponents with the recoil of their shots. Fast Tri-Angles and Boosters also use this stat to cut down smaller opponents. At max Body Damage, a tank can kill a Blue Pentagon by tapping them 3 times but because you are moving faster than the object getting knocked back it'll look like 1 hit but it's actually 3 hits happening under a split second. Also, avoid ramming tanks that have invincibility frames that just spawned, as they deal immense amounts of Body Damage without taking any. This has happened to few unlucky souls whom, have rammed just spawned in little tanks and have killed themselves, instantly giving that lucky tank tons of levels thanks to doing nothing.

Bullet Speed: This stat determines the movement speed of the projectiles shot by tanks. Increasing this stat increases the speed of bullets, and also increases how far they travel. Putting points into this stat increases the potential of surprising an opponent. Not only are they a sudden damage point on enemies, they may not even see it coming if maxed out. Increasing Bullet Speed makes bullets harder to dodge as well, and Destroyers with high Bullet Speed become extremely dangerous. It can slightly increase the damage, as when a bullet slows down by any reason, the damage decreases dramatically; having higher bullet speed could solve that problem, but a bullet with high speed already will not make any significant difference. Turns into Drone Speed if you become an Overseer, Overlord, Necromancer, or Manager. Unavailable if you become a Smasher or Mega Smasher, as they lack bullets.

Bullet Penetration: in essence is bullet health where each point put into Bullet Penetration increases how many objects a bullet can pass through before it's health reaches 0. This includes Polygons, Tanks, and other bullets. If bullets with no Bullet Penetration hit each other, they both get destroyed but if a bullet hits another bullet with lower bullet penetration then the penetrating bullet has its life lowered and therefore it will pass through less objects and if a bullet hits a tank with high body damage, the bullet will deal less damage because the tank has lowered the bullet's health to 0 before it can reach the maximum amount of collisions it can give and therefore lowered overall damage. Collisions with bullets will knock back the object hit and deflect the bullet in the process and if a tank with high health and body damage deflects a bullet (by being hit at the side) then the bullet only deals damage equal to the damage it can inflict at half the bullet penetration (health). If used wisely, this stat allows players to deal multiple instances of damage to a single Polygon or Tank. Turns into Drone Health if you become an Overseer, Overlord, Necromancer, or Manager. Unavailable if you become a  Smasher  or  Mega Smasher, as they lack bullets. Instead, it reads "Upgrade to"

Bullet Damage: Bullet Damage determines how much damage a bullet will deal in a single collision. Each point in Bullet Damage increases this amount. Turns into Drone Damage if you become an Overseer, Overlord, Necromancer, or Manager. Unavailable if you become a  Smasher  or  Mega Smasher, as they lack bullets. Instead, it reads "Windows 10".

Reload: Reload determines how fast a tank will fire bullets. An average tank upon spawning fires about every second. Some classes by default fire faster than others, but the Reload stat is percentage based. It doesn't decrease the seconds between shots, it increases the fire rate of the tank. For slow firing classes it such as the Destroyer or Sniper it is recommended to max this stat out. If planning on going with a summoning class like Overlord or Necromancer, consider maxing it out last, or not at all. As a Necromancer, to compensate for the fact that it doesn't spawn drones, the Reload stat adds extra minions which increase by 2 for each point. Overlords can benefit a bit from a lower delay between minion spawn times. Turns into Drone Count if you become a Necromancer. Unavailable if you become a  Smasher  or  Mega Smasher, as they lack bullets.

Movement Speed: This stat determines how fast a tank moves, not counting recoil. Naturally, the more points put into this stat, the faster a tank will move. Low-level players can upgrade this stat early to get out of dangerous situations or outrun more powerful opponents, this can increase the power of a Body Damage build because the main idea is that covering more distance than the enemy getting knocked back will equal to more collisions under a second which can mean the difference between a 1 hit or a 3 hit delete.

Trivia

 * After the June 15th update, when you upgrade to Overseer and above, Bullet Penetration, Bullet Speed and Bullet Damage will become Drone Health, Drone Speed and Drone Damage respectively. For Necromancer, Reload will also change to Drone Count.Drones.png have been changed to instead benefit Drones.]]
