Bless
Dawn's light turns one of your blocks into a healing block. It goes to an afflicted block first and cleanses whatever was on it, and to a block picked at random when nothing on the grid is afflicted.
In detail
Sunstone's proc on a Sun match. It turns one block into a healing block and clears any status on it. It takes a cursed block first, then ignited, then frozen, and otherwise a random ordinary block; it skips wrapped, petrified, healing and falling cells. The blessed block is a real healing block you still have to match to bank the HP, and clearing a status this way is free: no swap cost to put out a fire, no cost to lift a curse.
