The Picard ManeuverKeep it simple
JJROKCZI once argued with my DM that burning hands should allow me to melt the lock of a door, or burn a hole in the door where the lock and handle used to be at least. Think I ended up just blasting the front off the shop lol
If you burned sorcery point with shape spell, I could see turning it into a temporary blow torch, but it only lasts the one action. Even heat metal doesn’t melt things (except lead or aluminum which melt before they get “red hot”), but it would probably burn the wood around it or weaken the lock enough that it would bust if the door was rammed.
