This reaction is a set of multiple reactions happening in rapid succession. First, the SING dies and explodes, releasing radiation. The electrons from this then transform the EXOT into high tmp2 WARP, which creates intense heat and pressure. It also creates more ELEC, which combines with the rest of the radiation to make HYGN, and the heat and pressure of the WARP instantly cause fusion, and then burn the products later, making space for more HYGN.
