Whirlwind Battery evolves into Orbital Bombardment with Liquid Green Stuff. Use this Warhammer 40,000 pairing, upgrade the base weapon fully and open a boss-dropped chest. Tape Measure appears in older demo advice, but it is not the passive for this released-game route.
Assemble the Orbital Bombardment Recipe
| Role | Item |
|---|---|
| Base weapon | Whirlwind Battery |
| Required passive | Liquid Green Stuff |
| Evolution | Orbital Bombardment |
- Obtain Whirlwind Battery during your run.
- Equip Liquid Green Stuff as the matching passive.
- Complete the base weapon's upgrades.
- Open a boss-dropped chest and check the resulting name.
Liquid Green Stuff is the required passive; this icon does not depict the artillery weapon.
A passive being unlocked in the Armoury is not the same as carrying it now. Check the current loadout before changing unrelated weapons or chasing another chest.
Recognize Orbital Bombardment
The evolved attack calls barrages of voidship fire from above. That is the distinction to look for alongside the Orbital Bombardment name, rather than treating any large explosion as confirmation.
An acquired weapon can be wielded by a follower when your champion's keywords do not allow direct use. An ally delivering an attack is not, by itself, evidence that you chose the wrong evolution.
Separate the Battery, Rocket and Axe Recipes
| Base weapon | Passive | Result |
|---|---|---|
| Whirlwind Battery | Liquid Green Stuff | Orbital Bombardment |
| Storm Eagle Rocket | White Dwarf | Deathstrike Missile |
| Tempest Axes | Sabaton | Whirlwind Axes |
The words Whirlwind and Rocket do not make these weapons interchangeable. In particular, Whirlwind Axes is an Age of Sigmar evolution, not the artillery base weapon on this page.
If you followed an early demo combination, replace the recipe assumption with Liquid Green Stuff and check the actual base weapon's upgrade state. Glue is another separate passive. Use the rocket guide if you intended Deathstrike Missile, or Whirlwind Axes for the axe route.
