Editing Arenas (section)

== Tiers ==

Every Arena has three tiers of increasing difficulty and reward: '''Gamma''', '''Beta''', and '''Alpha'''. You must clear the lower tier before the next opens:

* '''Gamma''' is available as soon as the guardian is defeated.
* '''Beta''' unlocks after your first '''Gamma''' win in that biome.
* '''Alpha''' unlocks after your first '''Beta''' win in that biome.

{| class="wikitable sortable"
! Tier !! Difficulty (vs. guardian) !! Tribute cost !! Crests per win !! Primal piece chance (each) !! XP
|-
| Gamma || ×1.25 || 1 Artifact + 1 Trophy || 2 || 2% || ×1.0
|-
| Beta || ×2 || 1 Artifact + 3 Trophies || 4 || 5% || ×1.15
|-
| Alpha || ×3 || 2 Artifacts + 5 Trophies || 7 || 12% || ×1.3
|}

Difficulty is shown relative to the underlying story guardian fight, so a tougher guardian makes for a tougher Arena at every tier. The XP multiplier is modest (Gamma pays the same as the guardian; Beta and Alpha a little more) — Arenas are run for their '''rewards''', not their experience.

The '''Primal piece chance''' above is the ''tier's base rate, and it only applies at full strength in the deepest biome''. The actual chance scales with the biome's depth — roughly the tier rate × (biome position ÷ 10). So an Alpha win in the [[Sundered Vale]] pays the full 12%, but an early-biome Alpha pays a small fraction of it. Chase Primal pieces in the '''deepest arenas you can clear'''.
