Gwendolin is a Hero in Bloons TD 6. She is unlocked by reaching level 14. She shoots blasts of fire at bloons with her flamethrower. Initially, she pops up to 2 bloons at a rate of every 0.5s. At Level 4, she gains a passively generating Heat It Up attack that is triggered every 40 shots from her flamethrower. Starting at Level 5, she grants extra attack speed for Ring of Fire, Dragon's Breath, and Signal Flare. Almost every level improves her flame attack.

Mechanics

Flame

This section is incomplete. You can help out by expanding it. The editor who added this notice elaborates: Elaborate on improvements to flame projectile. Two flames is just like Bucc Double Shot, and not consume Alch buffs faster? Level 9 is true? Check projectile speed and projectile lifespan stats of all levels

Gwendolin's base attacks are flame projectiles. At base, each flame pops up to 2 bloons, deals 1 damage, and she attacks every 0.5s.

As she levels up, her flame attack is improved:

• Level 2: Pierce increased to 3
• Level 5: Pierce increased to 4
• Level 6: Flames add a burning damage-over-time effect. Burn deals 1 damage every 1.5s, for up to 3.1s.
• Level 8: Shoots two flames per shot.
• Level 9: Flames deal 2 damage, and burn damage per tick increased to 2.
• Level 10: Every level increases burn damage per tick by +1, starting from 3 at Level 10 and up to 13 at Level 20.
• Level 12: Attack cooldown reduced to 0.4s
• Level 13: Pierce increased to 8, increases projectile speed, and increases projectile lifespan.
• Level 15: Attack cooldown reduced to 0.3s
• Level 18: Attack cooldown reduced to 0.15s
• Level 19: Shoots three flames per shot.

Heat it up

Heat it up is unlocked at level 4. Gwendolin periodically triggers a burst of fire that damages nearby Bloons and buffs nearby towers. The attack triggers every 40 shots or after 1.5 seconds since it last triggered, whichever takes longer. It has 100 pierce, 38 range and deals 3 damage. The buff allows towers to pop Lead Bloons and frozen Bloons and lasts for 8 seconds. At level 7 the range increases by 5 and at level 11 it again increases by 3. At level 12 Heat it up now deals 10 damage, at level 15 Heat it up increases damage up to 20 and at level 18 Heat it up damage again increases to 30. At level 17 the Heat it up buff improves to give +1 damage and +2 damage to Lead Bloons.

Ring of Fire / Signal Flare / Dragon's Breath buff

Starting at level 6, Gwendolin reduces the attack cooldown and increases the projectile size of all Tack Shooters upgraded to Ring of Fire and above, Mortar Monkeys upgraded to Signal Flare and above, and Wizard Monkeys upgraded to Dragon's Breath and above by 10%. This buff has infinite range. At level 18, the effect increases to 20%.

Version 22.0

“

Gwendolin’s Heat it Up! attack/buff has been sitting in a weird spot where it would benefit from attack speed but does not because of the cooldown which prevents it ever having full uptime. This rework makes her have a roughly similar uptime at all levels without being buffed, however she will now benefit properly with increased uptime depending on any rate modifiers applied to her. A fully juiced Gwendolin around level 15 or 18 should now be capable of achieving 100% buff uptime

”

Levels	Changes
4+	Heat it up: cooldown reduced ― 15s → 4.5s
4–11	Heat it up: shots required to trigger increased ― 30 → 60
12–14	Heat it up: shots required to trigger increased ― 30 → 70
15–17	Heat it up: shots required to trigger increased ― 30 → 90
18+	Heat it up: shots required to trigger increased ― 30 → 110

Version 23.0

“

The last Gwendolin change didn't come through as well as intended for a number of reasons, so while keeping true to the intention behind this change it has been improved across the board to properly buff this again
— Update notes

”

Levels	Changes
4-11	Heat It Up: shot requirement reduced ― 60 → 40
12-14	Heat It Up: shot requirement reduced ― 70 → 48
15-17	Heat It Up: shot requirement reduced ― 90 → 64
18+	Heat It Up: shot requirement reduced ― 110 → 70

Version 26.0

“

As the Firestorm ability itself drops off later anyway, Gwen’s level 17 buff to Heat it Up will now apply to the version granted to all towers by Firestorm as well.
— Update notes

”

Levels	Changes
17+	Lv17 Firestorm’s full-map Heat It Up now also benefits from this level’s buff to Heat It Up Note: Firestorm Heat It Up now grants +1 to Lead and +1 Damage

Version 27.0

Levels	Changes
10+	Firestorm: No longer damages all Bloons with an additional instance of Heat it Up (bug fix)

Version 28.0

Levels	Changes
17+	Resolved issues with Gwendolin Lv17 firestorm’s Heat it Up buff (bug fix)

Version 29.0

“

Similar to Wall of Fire, Gwendolin’s Cocktail gains too much strength in grouped situations too early on and so this power has been pushed to higher levels.
— Update notes

”

Levels	Changes
3–6	Cocktail of Fire: Pierce refresh rate reduced ― 0.1s → 0.2s Note: Pierce refresh rate at levels 7+ remains at 0.1s
3–15	Cocktail of Fire: Cocktail stops popping Bloons when the Cocktail hits purples but this does not extinguish the Cocktail

Version 30.0

Levels	Changes
3+	Cocktail of Fire: Now disappears on contact with Purple Bloons (bug fix)

Version 31.0

“

Gwendolin’s Firestorm damage doesn’t carry well into the endgame so has been buffed at a later level.
— Update notes

”

Levels	Changes
16+	Firestorm: Base damage tic increased ― 1 → 5  Firestorm: MOAB-class bonus damage tic increased ― +9 → +10 Note: 15 damage total

Version 33.0

“

As she’s a little average all around these days with other heroes overtaking in the past years, Gwendolin is seeing some improved quality of life, synergization, and extra juice to the initial hit of Firestorm since currently the ability is, well, not heroic enough and the first impact does very little compared to the DoT.
— Update notes

”

Levels	Changes
3+	Cocktail of Fire: gains a target selection point, instead of targeting onto Bloons if Bloons in range or otherwise targeting randomly
5-17	Lv5 Pyrotechnics Expert: All Ring of Fire, Signal Flare & Dragon's Breath gain 10% rate & radius (This follows normal buff rules, applying to higher tiers, but not subtowers)
18+	Lv18 Pyrotechnics Master: Ring of Fire, Signal Flare & Dragon's Breath buff increased from 10% to 20%
10–19	Firestorm: initial damage increased ― 2 → 5  Firestorm: initial MOAB damage increased ― 2 → 20
20	Firestorm: initial damage increased ― 5 → 10  Firestorm: initial MOAB damage increased ― 5 → 50

Version 35.0

“

For now with a noteworthy direct comparison to Brickell and the use cases for these two heroes we have done a price swap keeping the lesser of the two at the lower price point. However as 750 would put gwen on the same cost as Striker Jones and we want starts with base 4 heroes to stay more diverse we have taken her down a little extra on top of that.
— Update notes

”

Levels	Changes
All	Placement cost reduced ― $900 → $725

Version 37.0

“

Removing the stacking aspect of Gwendolin’s burn damage over time, but increasing the damage as she levels up so that it actually scales up in power now.
— Update notes

”

Levels	Changes
6+
9+	Main attack: DoT damage increased ― 1 → 2  Main attack: DOT no longer stacks
9	Main attack: DoT damage increased ― 1 → 4
10+	Main attack: DoT damage now increases by 1 per additional level

Version 39.0

“

Gwen’s early game is just too much, especially far too excessive with the right combinations of knowledge / relic buffs so some of this power is being pushed up more with a makeup buff to cocktail at Lv7 where this has started to fall off by.
— Update notes

”

Levels	Changes
3–6	Cocktail of Fire: Pierce reduced ― 40 → 30
7+	Cocktail of Fire: Pierce increased ― 30 → 50
6–8	Main attack: Burn damage reduced ― 2 → 1
9	Main attack: Burn damage reduced ― 4 → 2
10+	Main attack: Burn damage reduced by 2

Version 41.0

“

Much more shifting of Gwen’s power to even her out into higher tiers

Version 42.0

“

Looking back over her kit, we noticed that we’ve never improved the actual attack itself for Gwen’s Heat it Up. Allowing her to be juiced up with high attack speed in order to spam these supercharged bursts of damage sounds fun and cool, so while noting that this will also increase the uptime of her buff we’re removing the limiter on her Heat it Up rate and pumping up its damage tenfold.
— Update notes

”

Levels	Changes
4+	Heat it Up: Pierce reduced ― Infinite → 100
12+	Gwen’s attack rate levels (Lv12, 15, 18) no longer reduce Heat it Up frequency
12–14	Lv12 Heat it Up damage increased ― 3 → 10
15–17	Lv15 Heat it Up damage increased ― 3 → 20
18+	Lv18 Heat it Up damage increased ― 3 → 30

Version 43.0

“

Gwendolin’s Heat it Up was recently reworked to allow for much more frequent triggering from attacks, however the 4.5s internal cooldown still limits it from being scaled up far so that internal cooldown is now also being reduced. Additionally, Heat it Up’s bonus buff to damage against Lead targets has been improved slightly so we can get more out of that niche.
— Update notes

”

Levels	Changes
4+	Heat it Up: Minimum delay reduced ― 4.5s → 1.5s  Heat it Up: No longer fails to apply if the attack runs out of pierce (bug fix)
17+	Heat it Up: Buff to Lead properties increased ― +1 → +2

Version 47.0

• Gwendolin Level 9 description changed ― Initial hit per blast pops 1 extra layer. → Initial hit per blast pops 1 extra layer. Gains increased burn damage and duration for every level.

“

Taking the opportunity to invest in some fire & water synergy
— Update notes

”

Levels	Changes
9+	DoT duration increased by +1s per level Note: DoT duration now between 4s–15s at Levels 9–20

Version 48.0

“

Gwendolin’s Lv10 Firestorm has been power-crept past by newer heroes and feels very lacking at this level for a fast XP curve hero.
— Update notes

”

Levels	Changes
10–15	Firestorm ability: DoT damage versus non-blimp Bloons increased ― 1 → 2 Note: Does not affect Level 16+ Firestorm DoT

Version 52.0

Levels	Changes

Version 55.0

Levels	Changes
8+	No longer loses her extra projectiles after being buffed after loading a save (bug fix)
