An excellent attack card that generates diamonds while dealing damage. At 1 Energy for 9 damage plus 1 diamond it is highly efficient and funds your diamond-consuming cards. The upgrade pushes it to 10 damage plus 2 diamonds, lifting efficiency further.

It is one of the core cards in Regent's diamond cycle, dealing damage while setting up the next big play. It pairs especially well with Radiant Flood (AoE damage scales with diamonds gained this turn), letting you attack now and prepare for the next turn simultaneously. Reliable from early to late game.

• Play it early in the turn to stockpile diamonds, then spend them on diamond-consuming cards later. This is the core diamond loop.
• Running multiples is viable. Consistent diamond supply improves synergy with Black Hole and Radiant Flood.
• The upgraded 2 diamonds is very strong. Upgrade priority is high.

• Radiant Flood: Damage scales with diamonds gained this turn, so playing Solar Strike first is very effective.
• Black Hole: Gaining a diamond also deals damage, so a single Solar Strike adds 3-4 AoE damage.
• Stardust: Spend all the diamonds accumulated from Solar Strike on a huge multi-hit attack.
• Crescent Spear: Damage scales with the number of diamond-consuming cards played, synergizing while you generate diamonds.
