Hitting an earth elemental with a stone to flesh spell currently has no interaction, which is odd. The following possibilities have been proposed:

• It turns into a flesh golem. However, stone to fleshing a stone golem already does this, and if earth elementals are loose rock compared to the specifically built body of a golem, it doesn’t make as much sense.
• It instakills the elemental and turns it into a pile of meatballs. This may be a little too cheap.
• As above, but the elemental gets the standard chance to resist.
• It cuts the elemental’s HP and max HP and drops some meatballs, but only actually kills the elemental if this would bring its HP to zero.

Xorns hit by the stone to flesh spell are briefly paralyzed, and while paralyzed, either take increased/double damage or are treated as if they have a worse AC.
