Other

- Cinderframe is a fire-themed frame focused on team support and DoT damage. Acquired through the new "Rise of Cinder" quest.

- **Ability 1 — Cinder Burst**: Launches a fireball that explodes on impact, dealing 500 damage and setting enemies ablaze for 8s.
- **Ability 2 — Ash Veil**: Creates a 10m zone of smoke that grants damage reduction to allies. Enemies inside are blinded.

- **Ultimate — Inferno**: Channels a 360° flame wave that deals 800 damage and pushes enemies back 8m.
- Cinderframe is a strong support pick for coordinated squads. The Brand mechanic rewards focus fire and turns the tide of long fights.
- The 1999 finale introduces a new questline that runs ~2 hours and ends with a final confrontation between the Hex and a new antagonist. The quest rewards:
- **Cinderframe warframe** (with full set)
- **Undercroft access** (endgame zone)
- **Cinder Aura** (cosmetic syandana)

- **Endless tiers** — Each tier is harder than the last. Tier 10 unlocks the "Undercroft Master" title.
- **Archwing** — Archwing missions now scale to your Mastery Rank. High-MR players get higher-level enemies and better drops.
- **Helminth** — Helminth can now subsume Cinderframe abilities. The most popular: Brand subsumed onto Mesa or Harrow.
- **Hildryn** — No changes. Still the best energy frame.
- Starting August 1, the year-end celebration event runs for 2 weeks. Daily login rewards, double credits, and a new ephemera. The celebration is the longest-running annual event in Warframe.
