Perks

Perks are in the run upgrades that provide passive benefits, helping you progress through waves and improve tower performance.

Perks are initially unlocked in labs. To access them you will need to unlock and complete the Unlock Perks lab at Tier 2 Wave 150 Milestone.

Use[edit | edit source]

Perks are extremely useful for farming with high wave count rounds. Their bonuses can accumulate and stack up and can significantly boost Coins farming rate or allow you to push for the higher waves.

Usually, you would like to go for specific perks that will help with farming and avoid perks that are useless.

Recommended Perks[edit | edit source]

Every player will have their own list of favorite perks, but in the early game most people would like to focus on specific perks during their runs and avoid the bad ones that either waste perk spot or even harm your run.

This list should help with the most farming runs. It's created with a eHP Blender build in mind, hence the Def and HP perks.

Good Perks. Those perks will benefit the run and will allow to get further or farm more coins:

Perk Wave Requirement - allow to get more perks.
All Coin Bonuses - Allows to get more Coins.
Defense Percent - higher Defense Percent will allow to survive more waves.
Increase Game Speed - Faster game speed, means more Coins / minute.
Golden Tower Bonus - More Coins from Golden Tower activation. Becomes even better if GT is Synced with BH and DW that gives even better multipliers
Max Health - more health means more eHP, means longer survival.
x1.80 coins, but Tower Max Health -70%
Enemies Damage -50%, but Tower Damage -50%
x1.50 Tower Damage, but Bosses Have 8x Health
Free Upgrade Chance for All - Not an amazing Perk, but still can help with free upgrades

Bad Perks. those Perks are either completely useless or harmful to the tower:

Interest - takes 5 Perk Picks for a useless bonus
Defense Absolute - takes 5 Perk Picks for a useless bonus
Health Regen - takes 5 Perk Picks for a useless bonus
Lifesteal x2.50, But Knockback force -70% - Knockback allows to push enemies into orbs and avoid damage.
Ranged Enemies Attack Distance Reduced, But Tower Ranged Enemies Damage x3 - Making ranged enemies stronger is always a bad idea.
Enemies Speed -40%, But Enemies Damage x2.5 - extra damage is always bad for eHP
x12.00 Cash Per Wave, But Enemy Kill Don't Give Cash - Cash per Wave isn't comparible with Enemy Kills Cash
Tower Health Regen x8.00, But Tower Max Max Health -60% - Health Regen is pretty useless.

Rest of the perks are considered to be more or less neutral, but you should maximize chances of getting good and useful perks during the run.

Perk Choice[edit | edit source]

Initially you can select from 2 perks generated at random. Perk choices can be increased to a max of 4 choices through the "Perk Option Quantity" lab.

The "First Perk Choice" lab will allow your selection to be guaranteed to appear on the first set of choices as the top choice.

When using the Auto Pick Perk, it will always select the top choice on the list, this will always pick your first perk choice.

Waves Required[edit | edit source]

Perks are earned starting at wave 200. After selecting 20 perks, waves required is increased to 250, 300 waves required after 30 perks, and 350 waves required after 40 perks selected.

The base can be reduced by upgrading "Waves Required" lab and by selecting the "Perk Wave Requirement" perk. Use the below formula to find the waves required.

Waves Required* = (Base Waves Required - Waves Required lab) * (1 - (Perk Wave Required Perk * (1 + Standard Perk Bonus / 100)))

*The formula should only be used to find the 1st perk for each base waves. If you get a decimal, you need to round the answer down. The rounded answer can be multiplied by number of perks.

EX: SPB of 8% and 3 PWR for PWR Perk for PWR 64.8%. 200 * (1 - 0.648) = 70.4 = 70 waves required.

Standard Perk Math[edit | edit source]

Most standard perks can be selected more than once in a round. The game has 2 formulas for multiplicative and additive perks.

For additive perks (Def %, Perks Wave Required):

Total Bonus = Base Value x Quantity x (1 + Standard Perk Bonus)

For multiplicative perks (Coin Bonus, Health, Damage):

Total Bonus = (1 + Base Value x Quantity) x (1 + Standard Perk Bonus)
