Deadly Assault | DMG and Points Breakdown
When fighting bosses in Deadly Assault, they have a unique Multiplier for their HP and ATK on top of their additional stat bonuses. This is consistent for every boss in Deadly Assault and changes based on how many bars of HP the boss has left. To match this, the Points gained per bar of HP destroyed also increases.
For example: Bars 29 to 26 (the first 4 bars of HP) have 1.2x higher HP than usual. Then bars 25 to 22 have 1.7x higher HP and 1.1x higher ATK. To match the higher HP, the Points gained is also increased.
