Overview

This is a card-art replacement pack, not a character skin and not a gameplay mod.

The Defect still plays exactly like The Defect. This mod only swaps the portrait images used on selected cards. It does not modify card names, descriptions, costs, damage, block, keywords, relics, powers, events, combat rules, Orb rules, run progression, or balance.

It is designed as a companion pack for Sereniel Defect Skin, but it can also be installed on its own if you only want the card-art theme.

Included Content

• Sereniel-themed replacement artwork for selected Defect cards.
• Selected Colorless, Curse, Event, Status, and Token card-art entries included in the package manifest.
• In-game mod-list cover and description metadata.
• Normal and ancient card portrait support.
• Standalone DLL/PCK package.
• No dependency on Sereniel Defect Skin.

What Stays Vanilla

• Possible conflicts: other mods that replace Defect, Colorless, Curse, Event, Status, or Token card portraits or patch the same card portrait UI fields.
• Multiplayer: this is a local visual replacement. Other players do not need to install it.
