Grants the socketed card all color triggers simultaneously (Red, Blue, Yellow, Purple). Satisfies every color-based synergy condition with a single gem.

• Effect: All color triggers (Red/Blue/Yellow/Purple)
• Type: Color Synergy Gem
• Stacking: One copy is sufficient (all colors already covered)

• Color-agnostic finishers: Satisfies all color requirements regardless of Crawler or Arcana
• Combo starters: Fires every color-based combo synergy simultaneously
• Support cards: Universal color coverage for any build

• Pugnala (Yellow trigger): Her yellow-card draw passive is always active
• Arca (Purple trigger): Her purple-card mana passive is always active
• Color-specific Arcanas: One gem handles any color Arcana that appears in the run

Dramatically increases build flexibility. When color restrictions appear due to Crawler/Arcana combinations, this gem resolves them entirely with a single socket.
