- Unlock: Apex Challenge opens at AR 40. Its materials forge Apex Weapons, and you choose the element.
- Rarity: they start at R9. Each rarity from R10 to R14 opens one awakened effect slot.
- Awakened effects: these are random. Once every slot is awakened you can temper the weapon to reroll them, with a chance at Legendary effects.
- Where bonuses work: the game lists Apex-exclusive abilities as active in Apex Challenge, Monster Challenge and Limited-Time Challenge events, and many are marked Season 0 only.
