Child of the Stars

RegentPowerUncommon
Whenever you spend , gain 2 Block for each spent.

Once played, every time you spend Stars you gain 2 Block per Star (3 upgraded). It only fires on your own spending and on amounts above zero. The Block is added flat, so Dexterity and Frail do not change it, and a second copy adds another 2 per Star. Comet's 5 Stars become 10 Block, Seven Stars' 7 become 14, and Decisions, Decisions' 6 become 12.
