Endu upgrades, Storm Gem and Akunra
Quick answer
Wind Gems extend movement; the Storm Gem and Akunra are separate collection and forging milestones.

Use separate checkboxes
The official Steam achievement definitions distinguish collecting Endu, recovering all five Wind Gems, obtaining the Storm Gem and forging Akunra. Completing one objective does not automatically complete the others.
What to prioritize
If the problem is crossing a gap, inspect dash charges rather than farming weapon damage. If the problem is weak attacks, check your power meter, weapon matchup and combat progression. These are different problems and should not share a single upgrade checklist.
Forging scope
Akunra’s existence and forging objective are official. The currently verified source does not provide the complete recipe or all prerequisite item locations. This page therefore provides an accurate milestone checklist rather than inventing a forge interaction or promising that five gems automatically create the sword.
