mob standing on top of a magma node that belongs to the "fire" group. The magma node has also been added to the fire group, making it so that standing on the node will do damage to the mob. In official Minecraft, magma blocks just do fire damage without the fire animation. Source: https://minecraft.fandom.com/wiki/Magma_Block
