Similar to many enemies encountered in Stories of Legend from sub-chapter 21 and onward, Boraphim has a rapid attack rate, high attack power (Both of these giving him deadly levels of DPS, even higher than that of his darker sibling) and moves quite quickly. Unlike his counterparts, it has 5 knockbacks instead of 2, which help to keep at bay his insane pushing power, however, this can also lead to your units to get killed by the backlines, so be wary about that.
Anti-Angel cats are almost required to kill Boraphim. Ramen Cat is a strong meatshield, for it takes many hits from Boraphim before dying.
If you have Momotaro or Dark Merchant Babil, they can really help against Boraphim. Momotaro can permafreeze, while Babil can deal 100k+ hits constantly.
If you don't have Momotaro, a stack of Juliet the Maikos can be used to permafreeze Boraphim instead, or a stack of Catophones to slow him if you haven't obtained Juliet yet.
Use Awakened Bahamut Cat. He outranges this enemy and has high DPS. However, this unit can easily kill Awakened Bahamut in 2 hits, so don't stop meatshielding if you are going to defeat him using this strategy.
Dioramos (True Form is strongly advised) can easily eliminate this enemy with backup from strong meatshields (preferably Ramen Cat) fairly quickly, as it has a proper amount of DPS, and his knockback + slow ability can prevent him from wreaking havoc to your backline. His high HP can make him an emergency wall in case another enemy makes Boraphim push to him as well.
