Signal Flare (BTD6)

Signal Flare is the Mortar Monkey's path 3 tier 3 upgrade in Bloons TD 6. It adds a new wider explosion that removes the Camo property of any Bloon, including DDTs, that it hits, dealing zero damage. The Mortar also gains camo detection. This secondary explosion has 50 pierce and 52 radius (90 pierce and 72.8 radius with 1-0-3).

Strategy

This section was last updated for: version 53.2

Signal Flare is a cheap and fairly reliable de-camo option. It functions the best on maps with one active lane per round, where its reliability can be further maximized by targeting on a bend near the entrance, but can still be used with active micromanagement on other maps. It does struggle against Round 78's Camo Ceramic clump, which requires micromanagement regardless of the map.

0-2-3 is generally preferred, improving its consistency on all map formats, particularly against Camo Pinks. On a consistent bend, such as the beginning of Geared, 0-1-3 can be enough to reliably decamo DDTs. 1-0-3, while cheaper than 0-2-3, is not very good outside of Race conditions.

  • "Mortars should no longer display line of sight as they can ignore all blockers"
  • "The mortar’s projectiles should no longer visually drop back down the barrel"
Mortar’s Faster Reload feels like a ‘required’ as a crosspath with Burny Stuff never scaling well on any path but it’s own. We like choices not requirements so to counter this we have made Burny Stuff scale with top-path damage & shifted a small amount of the speed from Faster Reload onto the base mortar and reduced base accuracy considerably.
— Update notes
  •   Mortar base rate of fire increased ― 2.2s → 2s
Signal Flare has had its camo revealing aspect reworked to make it more generally useful.
— Update notes
  •   Now triggers a larger secondary AoE at the point of impact that removes Camo and ignores Bloon immunities
  •   Main explosion: No longer removes Camo
Bottom path Mortar burns have been reworked to burn faster and last longer at all upgrades; the Extra Burny Stuff MK has been tweaked in order to keep it’s benefit the same comparatively to the new & improved base values.
— Update notes
  •   DoT: Damage interval decreased ― 1.5s → 1.25s
  •   Decamo AoE: No longer affects DDTs without   Paint Stripper (bug fix)
1-0-3, 2-0-3
  •   Decamo explosion pierce increased ― 80 → 85 (bug fix)
  •   Decamo explosion radius increased ― 50 → 70 (bug fix)
Other similarly priced decamo options are able to decamo DDTs, so Signal Flare feels like a far lesser choice here having this basic decamo utility locked behind Monkey Knowledge, so that’s being freed up.
— Update notes
  •   Signal Flare can now decamo DDTs
As the camo property has grown quite weak and currently Signal Flare is considered the best decamo tool, we want to push back slightly on its cost and by reducing the blast radius of the decamo area while emphasizing crosspathing for effectiveness there.
— Update notes
  •   Upgrade cost increased ― $700 → $800
  •   Decamo: radius reduced ― 50 → 43
1-0-3, 2-0-3
  •   Decamo: Bigger Blasts pierce bonus increased ― +5 → +10
We’re looking to shakeup mortar in a couple small ways this update, along with Striker Jones changes noted further on for ‘multi-mortaring’ synergy. From the base level Mortar has far more pierce than should ever be necessary at low rounds but doesn’t hit beefy enough for the low fire rate, so we are trading up some base pierce for damage, instead moving this lost pierce up into crosspath.
— Update notes
  •   Explosion: Damage increased ― 1 → 2
  •   Decamo explosion: Pierce reduced ― 80 → 50 (undocumented)
    • Note: Bigger Blasts crosspath remains at 90 pierce
  •   Explosion: Pierce reduced ― 40 → 25
    • Note: Bigger Blast and its subsequent upgrades unchanged
Signal flare is too effective a cheap full map de-camo though a little unreliable due to the lower rate & low radius of de-camo, cost is increasing a little but also with greater radius for the de-camo area to improve reliability
— Update notes
  •   Upgrade cost increased ― $800 → $900
  •   Signal Flare camo removal radius increased ― 43 → 52
Most of the reduced price from this change [base tower] has been moved into Signal Flare, though left out of the other T3 crosspaths since we feel they are fine receiving the small buff.
— Update notes
  •   Upgrade cost increased ― $900 → $1,000
    •   Overall cost reduced by $50 (due to cost changes for previous tiers)
No big shakeup for Mortar right now, but upon review of crosspaths we felt some low-end pricing wasn’t well balanced. These adjustments should improve early-game options without touching the core power of the tower.
— Update notes
  •   Upgrade cost increased ― $1,000 → $1,100
    •   Overall cost is unchanged (due to cost changes for previous tiers)
