Target up to 2 creatures you can see. Those creatures must make a wisdom saving throw. On a failed save, the target(s) suddenly perceive the floor around them to be lava. At the beginning of their turns, they must use their actions to attempt to retreat to higher ground such as a table, stairs or other raised surface. Once there, they can take actions as normal but will not re-enter the lava for any reason until the spell has ended. If they fail to find higher ground they will attempt to climb walls or even other creatures to get away from the lava. On a successful save, the target(s) are unaffected.
This spell does not affect creatures who aren't concerned about being in lava, such as fire elementals.
At Higher Levels. When you cast this spell using a spell slot 2nd or higher, the number of potential creatures you can target increases by 2 for every spell slot above 1st.
