To deploy two Tier 5 Crossbow Master Dart Monkeys in a single match of Bloons Blitz, you must unlock the Master Double Cross node in your Monkey Knowledge tree before starting your run. Without this prerequisite research, the game limits you to a single Tier 5 tower per path, blocking the purchase of the second Crossbow Master regardless of your cash total.
Unlocking and Placement Rules
Once Master Double Cross is active in your Monkey Knowledge tree, you can purchase two Tier 5 Crossbow Master upgrades on separate Dart Monkeys within the same match.
To maximize the impact of both towers, follow these positioning guidelines:
- First Crossbow Master: Place this tower in a central location with a clear line of sight over the longest straight track segment to hit incoming targets early. Aim to have this first Tier 5 active by Round 60 to stabilize mid-game defense.
- Second Crossbow Master: Place this tower in a complementary location, such as near the lane exit or covering an alternate track pathway that the primary tower cannot reach.
- Spacing: Avoid placing both towers on the exact same tile. Separating them creates unique firing angles, reduces wasted bolt pierce, and ensures continuous coverage if terrain features temporarily obstruct one tower's line of sight.
Mid-Game Economy and Upgrade Sequence
Purchasing two Tier 5 upgrades requires significant gold management throughout the early and middle rounds. Rushing both towers without support leaves your defenses vulnerable to wave leaks.
- Establish Early Economy: Build cost-effective secondary towers, such as Banana Farms or Alchemists, during early rounds to build liquid capital.
- Buff the First Master: Apply the Alchemist's "Berserker Brew" buff to your primary Dart Monkey. This extends its clearing power so you can safely bank funds instead of over-defending.
- Fund the Second Master: Once your first Crossbow Master is operational around Round 60, redirect your surplus income exclusively toward buying the second Tier 5 Dart Monkey upgrade.
Strategic Limitations and Map Suitability
While dual Crossbow Masters deliver high long-range damage, spending heavily on two Tier 5 units creates distinct tactical vulnerabilities:
| Scenario or Map Condition | Performance | Recommendation |
|---|---|---|
| Open maps with long straightaways | Optimal | Bolts utilize maximum range and pierce against straight lines of Bloons. |
| Maps with tight curves or heavy line-of-sight obstacles | Poor | Targets exit bolt paths quickly, wasting pierce potential; select an area-of-effect Tier 5 instead. |
| Fortified MOABs and dense Ceramic rushes | Vulnerable | Heavy investment limits cash for support units; bring a Glue Gunner or Monkey Village for slow and stripping effects. |

This helped me understand strategy much better.
Good guide for Bloons Blitz players. The strategy part was useful.
Nice guide. I am checking the other Bloons Blitz articles next.
