回声室#700

Echo Chamber is an unlockable passive item added in The Binding of Isaac: Repentance.

• This is possibly a reference to the card Eye of the Storm from Magic: the Gathering, as the item resembles the art of the card and both result in previous effects being reused when a new one is activated.
• This is also possibly a reference to the card Echo Form from 'Slay the Spire', which will duplicate the card effect of the first card played per turn.
• Before the 1.7.7 patch, Echo Chamber was able to copy the effects of all previously used cards and pills, enabling many powerful synergies such as getting infinite cards and pills with Ancient Recall.
• Echo chamber is a term for the act of surrounding yourself with people and media that only support and agree with one's views and excluding any opposing views or criticism.
• Echo Chamber appears to be a Tarot Card and a Playing Card being sucked into some kind of vortex. Card Modifiers Items
