World name: Hyperion
Character name: Sol Aureus
NPC name: N/A
Monster name: Clockwork Soldier
Class/Level: Summoner / 50
Party or solo: Party
In-game time: Did not record
Area and coordinates: Drive Cylinder (The Binding Coil of Bahamut - Turn 4)
Steps:
1. Enter The Binding Coil of Bahamut - Turn 4
2. Progress to a phase with a Clockwork Soldier
3. Apply a Damage over time effect on the Clockwork Solider, such as Bio, Bio II, Miasma, or Thunder. Notice that the Damage over Time effects are dealing 0 damage.

This is crippling for a Summoner in particular, as Damage Over Time spells are quite a large chunk of a Summoner's damage. Since these enemies can only be taken down by magic damage and this particular Turn is a damage race, players will have an aversion to bringing Summoners as they will not be able to kill the Clockwork Soldier fast enough, or at least not nearly as fast as a Black Mage.
