d20pfsrd - Converted for 5e
9-level Evocation
This spell causes a destructive resonance in a corporeal creature’s body. Each round you concentrate (including the first), you can cause one creature to collapse in on itself, inflicting 10 points of damage for every 2 Cleric Levels and have their movment reduced to 0 until the beginning of your next turn. If you break concentration, the spell immediately ends. You can target a particular creature only once with each casting of the spell. Implosion has no effect on creatures in gaseous form or on incorporeal creatures.
