A cost 0 attack-plus-debuff card that consumes 3 diamonds. Despite being a Skill it packs an exceptionally rich kit: 13-18 damage plus 2 Weak plus 2 Vulnerable. You can think of it as a strict upgrade over Falling Star (spend 2 diamonds, 7-11 damage, 1 Weak, 1 Vulnerable).

Because it costs 0 Energy it also triggers Monologue (gain 1 Strength per card played) and counts toward Execute (returns to hand after playing 3 Skills). The 3-diamond cost is heavy, but with Genesis plus other diamond generators you can keep the resource flowing.

• It consumes 3 diamonds, so play Genesis (2-3 diamonds) or Shimmer (1-2 diamonds) earlier in the turn before casting it.
• As a Skill, it counts toward Execute's "play 3 Skills to return to hand" trigger.
• The 2 Vulnerable increases all follow-up attack damage by 50%. Chain a strong attacker right after Gamma Blast.

• Execute: Returns to hand after playing 3 Skills. Gamma Blast counts because it is a Skill.
• Monologue: Gain 1 Strength per card played. A 0-cost Skill like Gamma Blast is an ideal trigger.
• Genesis: Supplies 2-3 diamonds each turn, roughly covering Gamma Blast's cost on its own.
• Radiant Flood: Stockpile diamonds before playing it, and Gamma Blast's diamond gain boosts Flood's damage too.
