Meta Unit

This unit is currently in the meta, which means they are the one of the best and most effective units in the game.

Overview

Onwin is a 5-star support tower based on Erwin Smith from the anime Attack on Titan. He increases the damage of units within his range with a manual ability (called Shinzou Wo Sasageyo) by a specific percentage, which is shown as Erwin's damage stat. This ability’s effect lasts 30 seconds and has a 60 second cooldown. Erwin does NOT directly attack troops and cannot be used on his own. Erwin is only obtainable from the Hero Summon and is not a part of any evolution.

Shinzou Wo Sasageyo

Onwin Shinzou Icon.png

Shinzou Wo Sasageyo (which translates to give/offer your hearts) is an ability that allows Erwin to increase the damage stats of units in his range by a certain percentage.

  • Shinzou Wo Sasageyo's effects do NOT stack. Using Shinzou Wo Sasageyo on a troop already affected by it does NOT add to the time or buff amount, instead nothing happens. Using Shinzou Wo Sasageyo to boost the effect of another Erwin will stack the effects of the ability as long as the troops were not affected by the initial ability.
  • Erwin doesn't buff by only 95%. The maximum amount of damage buff players can get from Erwin is 200%, which triples a unit’s damage. As such, the Bomba Orb is the best possible orb to use on a level 80 Erwin, as he will have just over a 200% damage boost when buffed by another maxed out Erwin.
  • While multiple buffs can not be applied to the same unit, the effect of a single buff can be increased by chaining uses together. The damage increase after N chained buffs will be B(BN-1)/(B-1) with a hard cap of 2, where B is the buff amount as a fraction (0.5 at level 1, 0.895 at level 80).
  • The max of +200% can not be reached until 67%, where it will take 11 chained uses. 74.5% will take 4 chained uses, and 81.5% will take 3 chained uses. A chain alternating between 81.5% and 48.9% will eventually reach 200% on the fully upgraded ones, allowing players to save Cash.png2,000 when making a chaining square.
  • Using four Erwins in the same spot allows for infinite chaining at full uptime by using one every 15 seconds.
  • The line method is a way to stack Erwin buffs by lining them up in the direction of the targeted troops, although with the limit on the damage buff being in place, it's not a good choice anymore with the chain method existing.

Tips

Although Erwin does not see any increase in his maximal damage buff after a certain point, it is still beneficial to level him up and use damage orbs on him to reach the buff cap as fast as possible.

If you were to chain buff infinitely without ever messing up and without regard for how long it would take to reach, then you would have no use for having an Erwin that does anything more than 67 damage at max upgrade.

However, Erwin's damage plays a much greater importance when it is necessary for you to buff as soon as possible or without enough money to afford a chain. When playing with many people especially, Erwin buffs at an early round can serve to massively increase damage output and save others from having to upgrade their starter units. This is when having a level 175 Erwin with Fire Orb undoubtedly excels a level 80 Erwin with Bomb Orb. That being said, it is rarely necessary to go to such extremes and should realistically only occur in gamemodes with a finite wave count.

A hard cap of 200% damage is in place. Don't go overboard and waste any precious placements trying to get an insane buff!

Selling

Erwin cannot be sold. Considering the importance of this unit, you should be EXTREMELY careful before placing him.

Trivia

  • Erwin has been in the meta ever since he was released, primarily because no other unit has been released that can replace his damage boosting effect. By extension, this unit has been in the meta longer than any other unit.
  • Erwin is one of the few units in the game with a voiceline, saying "Shinzou wo sasageyo" when using his ability.
  • Erwin was the first unit added to the game that buffs the damage of other units, with the second being Brook (Artist), added much later.
