Attach to the left arm
Select Dust Devil Glaive in your hand, choose Play gear, then select the highlighted left-arm attachment spot on Dust Devil. Confirm Play gear after checking the three highlighted bank RAM.
Why this matters
Both of Dust Devil's level-two arm ports can hold this Glaive. Use the left arm for this lesson. Paying for gear turns the three bank RAM sideways; they stay in the bank. Dust Devil's two attached RAM stay attached.
