Your dial cells are considered 0% resist targets. The unbreakable statuettes that Dragon Pig may sometimes create are also considered 0% resist targets.
If you attack a dial cell, whether it be with Xelor's Punishment or attacking Dragon Pig while he's standing on a dial cell, you will generate Belligerence based off of how much you hit Dragon Pig as well as how hard you would hit against a target with 0% resistances. This means you can easily climb 100-200 Belligerence in a single turn, which is beyond the point of saving you from Dragon Pig teleporting out.
Likewise, if Dragon Pig is diagonal from a statuette, hitting him with Hand on a Tock turn will generate Belligerence based off of how hard you hit Dragon Pig plus how hard you hit a 0% resist target since the attack will bounce to the statuette.
Healing will also generate a large sum of Belligerence. Mummifying a downed ally will have a similar effect, since not only are you resurrecting them, but you are also healing them for a percentage of your own HP.
Be wary. It's an easy way to ruin an otherwise simple strategy.
