In Lego Batman Legacy of the Knight, all 5 WayneTech Caches in the Botanical Gardens mission are available: 1) behind the waterfall, 2) on the flower-step climb near the scientist, 3) in the Carnivorous Plants room, 4) under the first slamming vine, and 5) behind the vine wall at the final grapple point.
How to get every Waynetech cache during the Botanical Gardens mission
Step 1: Take the waterfall route
Move to the left-side waterfall in the Botanical Gardens mission.
Use the Batclaw on the rock above it. That opens the hidden passage behind the water.
Make sure to hop onto the pods to get there.
And get your first WayneTech Cache.
Step 2: Build the flower stairs
When you reach the scientist area, switch to Robin.
Hit the three flower targets so the petals form climbable steps.
Go up the petal path.
And collect the second cache at the top.
Step 3: Clear the plant room cache
In the Carnivorous Plants of the Tropics room, turn around from the main path.
Use a Batarang to trigger the plant guarding the cache.
Once it is safe, grab the third cache.
Step 4: Slip under the vine trap
In the vine room, wait for the first slamming spiked vine to lift.
Then drop underneath it and collect the fourth cache hiding below.
If the timing feels tight, approach from a stop instead of sprinting so you can adjust mid-step.
Step 5: Open the final vine wall
At the end of the sequence, look up and right for the two hook points, then use Robin’s cable tether to pull the vines apart.
Zip through the opening.
And claim the fifth and final WayneTech Cache for Botanical Gardens.
Common mistakes
-
Missing cache 1 because the waterfall path is easy to pass by when following the main route.
-
Trying to climb the flower section without using Robin, which slows the route down.
-
Standing too close to the carnivorous plant before detonating it. Use a safe angle and then move in.
-
Rushing cache 4 and getting clipped by the vine trap, which can knock you back into the room.
-
Forgetting to look up at the end, since cache 5 is locked behind the vine wall rather than sitting on the main path.
Each WayneTech Cache gives a WayneTech Chip, and chips are the currency used for gadget and weapon upgrades at workbenches. The Botanical Gardens mission is also one of the cleaner mission-level cache runs because all 5 are collectible in a single pass if you know the route.
