Tack Shooter

“

The nerf to Blade Shooter was slightly too much. This should allow it to perform better against early rushes.
— Update notes

”

Tiers	Changes
X-3-X Blade Shooter	Corrected description ― Switches tacks out for sharp blades that can pop up to 2 additional Bloons. → Switches tacks out for sharp blades that can pop up to 1 additional Bloon.

Sniper Monkey

“

Sniper is picked more often purely because it comes with efficient cash generation, so we are changing that to spread its effectiveness across all three of its paths

Monkey Buccaneer

“

Merchantmen have been too powerful as early game defence and money making. We are making it more of an investment to get the Merchantman while keeping their efficiency the same
— Update notes

”

Tiers	Changes
X-X-3 Merchantman	Upgrade cost increased ― $1,500 → $2,000
X-X-3 Merchantman (further upgrades unaffected)	End-of-round cash generation increased ― $350 → $400

Monkey Ace

“

Neva-Miss was carrying early defence. This change to the upgrade will make it more about the increased accuracy and not the increased pierce. Spectre was also providing too much value for its cost.
— Update notes

”

Tiers	Changes
X-X-3 Neva-Miss Targeting	Dart: No longer gains +2 pierce Note: Pierce decreased from 11 to 9
X-X-4 Spectre	Upgrade cost increased ― $20,000 → $24,000

Heli Pilot

“

Heli is quite under utilized on maps that aren’t Bloon Bot Factory. These changes should make it a more viable tower for other maps.
— Update notes

”

Tiers	Changes
X-4-X Support Chinook	Upgrade cost reduced ― $8,500 → $7,500
X-X-4 Comanche Defense	Passive ability: Duration increased ― 15s → 20s

Druid

Tiers	Changes
4-X-X Ball Lightning (and further upgrades)	Lightning ball: Projectile now ignores Purple Bloons (bug fix)

Engineer Monkey

“

Sentry Expert is proving too cost-effective as a reactive response to a rush. Sentry Champion was not scaling as well as we would have liked with the bottom path. Bloon Trap income has no easy answer on separated lane maps, so this should make it feel less oppressive to play against.
— Update notes

”

Tiers	Changes
4-X-X Sentry Expert	Upgrade cost increased ― $2,800 → $3,250
5-0-1 Sentry Champion + Oversize Nails 5-0-2 Sentry Champion + Pin	Sentry: Pierce bonus changed ― +1 → +25% Plasma: 6 → 6.25 Explosion: 100 → 125

Banana Farm

“

Buccaneer was getting too much value from this upgrade, so we are tuning it back a bit.
— Update notes

”

Tiers	Changes
X-X-4 Central Market	Updated description's stats, showing "+5%" instead of "+10%"
X-X-4 Central Market (and further upgrades)	Merchantman buff: Income bonus decreased ― +10% → +5% Note: Max stack income bonus decreased from +100% to +50%

Ocean Obyn

“

Ocean Obyn's pierce buff scales too well on on some towers early game. This should allow those towers to still benefit from this upgrade later in the game but not become too strong early game.
— Update notes

”

Levels	Changes
2-8	Ocean's Wrath: Pierce benefit to water towers changed ― +1 → +25%
9+	Ocean's Wrath: Pierce benefit to water towers changed ― +1 → +50%

Pat Fusty

“

Pat has not been getting much use lately. This should hopefully allow him to perform better in the early and mid game.
— Update notes

”

Levels	Changes
3-13	Rallying Roar: Now grants +1 pierce to affected towers
14+	Rallying Roar: Now grants +2 pierce to affected towers

Bonnie

“

Bonnie was performing better than other heroes early game, allowing her to snowball. This change will bring her closer to the value provided by other heroes.
— Update notes

”

Levels	Changes
2+	Cart — Tier 1: Cost increased ― $300 → $330  Cart — Tier 2: Cost increased ― $1000 → $1100
5+	Cart — Tier 3: Cost increased ― $2700 → $2970

Bug fixes

• "Fixed misleading icon on Ocean Obyn’s summary screen."

Development

Some balance changes have derived from a post by u/qwertyxp2000 on r/battles2, who suggested balance changes that they stated would more appropriately balance various towers and Heroes that got changed in version 4.12. Ninja Kiwi used similar wording for justifying balance changes in their official patch notes. The following are the changes that were accepted into version 4.13:

• Sniper Monkey
  • Reverting Sniper Monkey's attack cooldown increase
  • Increasing Shrapnel Shot's cost from $250 to $300
  • Decreasing cash generation of Supply Drop ($2000 → $1750) and Elite Sniper ($5000 → $4500)
  • Decreasing Semi-Automatic's cost from $2200 to $2100
  • Removing the +1 pierce of 0-2-3+ Shrapnel Shot.
  • Increasing damage of Deadly Precision (20 → 30) and Maim MOAB (30 → 45)
• Monkey Ace
  • Removing +2 pierce from Neva-Miss Targeting
  • Increasing Spectre cost from $20,000 to $24,000
• Engineer Monkey
  • Increasing Sentry Expert cost from $2800 to $3250
  • Changing pierce bonuses for 5-0-1 Sentry Champion's sentries from +1 to +25%
  • Decreasing cash value of Bloon Trap and XXXL Trap by two-thirds.

Notes

• The official patch notes state that the Blade Shooter change is an "attack speed increased by 15%", but more likely is just an attack cooldown reduction by 15%.
• Shrapnel Shot previously had +2 Camo damage, which is corrected to +1, which the official patch notes refers as a bug fix ("Fixed Sniper Monkey dealing too much damage to camo bloons with Shrapnel Shot"). That balance change was supposed to occur in version 4.12's base update but was not included due to an oversight.
• The first phrase for the Sniper's official patch notes, "Sniper is picked more often purely because it comes with efficient cash generation", uses exactly the same wording as the post written by u/qwertyxp2000.
• The phrasing used to describe Bloon Trap's nerfs in the official patch notes, "Bloon Trap income has no easy answer on separated lane maps" has almost the same wording as used by the post by u/qwertyxp2000; the only difference is using the full name "Bloon Trap" instead of just "Trap".
