Sun
Dagaz (ᛞ), the orange rune. No hero and no realm claims Sun yet, so it works as pure fuel: it chains and combos exactly like anything else on the board. A realm will lay claim to that radiance eventually.
In detail
Block 4. The glyph is the rune Dagaz, which means light; the Norse theme labels the element Sun, a name kept from when the game shipped with five elements. Sunray Focus adds 0.15 spawn weight.
