Talk:Type 91 Armor Piercing Shell/@comment-25435890-20141104082550/@comment-24980562-20141104114916

Actually, AP Shells do increase damage and accuracy against heavily armoured enemies and installation type bosses, but it only applies to day battle shelling phases. So I guess ships with AP Shells can now deal with them in day battle while those with Type 3 Shells deal better damage at night.
