However ZUN sets a damage penalty when you
shoot on top of an enemy AT LEAST FROM TH11.

Shots and bombs do full damage to nonspells and kodamas , do 1/7 damage to spellcards.
Numbers stand for damage per second to nonspells(spells).
Junko has a larger hitbox than other bosses.

bombing ontop of the enemy will do more damage.
however in general , bombing and shooting downsides does more damage than bombing close and shooting unfoused.
