I think in the example below, どのダンジョンも・・・ means "whichever dungeon". The advice applies to any dungeon in the game. Can somebody confirm this for me please?
どのダンジョンも、前半はダンジョンアイテム探し、後半は入手したダンジョンアイテムを使っての攻略となる。ダンジョンアイテムはボスにも有効だ。
I imagine this is a standard pattern but I can't say I have seen it a lot in my experiences of Japanese.
