Challenge Rarity Rewards

Per-planet challenges award warp crystals (gems) and planet XP bounty on completion. Both rewards scale with the challenge’s rarity tier. Gem rewards are flat across all planets; XP rewards are scaled per-planet by a bounty multiplier so that harder planets pay out proportionally more XP (since their completion thresholds are also higher).

Reward table

Rarity	Gems	XP Base (Landing Site)
Common	5	30
Uncommon	15	60
Rare	40	150
Epic	100	400
Legendary	300	800

Gem values are constant across every planet. The XP column above is the base value used on Landing Site (PLANET_XP_BOUNTY_MULT = 1.0); higher-difficulty planets scale this number up.

Planet XP bounty multipliers

XP bounty for any challenge is computed as round(XP_BASE[rarity] * PLANET_XP_BOUNTY_MULT[planetId]). The multiplier matches each planet’s threshold scaling so that the XP-per-effort ratio stays roughly consistent across the difficulty curve.

Planet	Multiplier
Landing Site	1.0x
Sunrise City	1.5x
The Voidstar	2.0x

Worked examples:

• Common challenge on Sunrise City: 5 gems + round(30 * 1.5) = 45 XP.
• Legendary challenge on The Voidstar: 300 gems + round(800 * 2.0) = 1,600 XP.
• Epic challenge on Landing Site: 100 gems + round(400 * 1.0) = 400 XP.

Placeholder planets (Solaris, Speedway, Eden, Old Earth, Network Station, Delphi, Desolation, Obelisk) currently use a 1.0x multiplier until their content is authored.

Challenge ID format

Every challenge has a stable, deterministic ID built from three parts:

{planetShort}_{category}_{rarity}

• planetShort — two-letter planet code (ls Landing Site, sc Sunrise City, vs Voidstar, plus placeholders so/sp/ed/oe/ns/dp/ds/ob).
• category — tier, kills, or events.
• rarity — common, uncommon, rare, epic, or legendary.

Examples: ls_kills_common, sc_tier_rare, vs_events_legendary.

This format gives exactly 15 challenges per planet (3 categories x 5 rarities) and 45 total across the three live planets.

Why it’s structured this way

• Flat gem values keep the metagame economy legible — a Rare challenge is worth 40 gems no matter where you earn it.
• Per-planet XP scaling prevents Landing Site grinding from being the optimal XP path; harder planets pay more XP per challenge because their thresholds demand more.
• Run vs lifetime scope is set per-rarity inside each category: tier challenges are always per-run, while kills/events split per-run for Common/Uncommon/Rare and lifetime for Epic/Legendary.
