Capping Enemy damage to 1 HP regardless of source

Introduction

The Apparitions event gives you the only opportunity to gain a colorless card called Apparition.  The Event provides you with 5 cards but only at the cost of 50% of your max HP.

These cards provide you with 1 intangible, which reduces all damage to 1 HP that turn.  Very useful but also a bit frustrating to use.  Losing half of your HP makes you very vulnerable to attacks when you are not intangible.  The cards also exhaust, meaning they are removed from your deck hand for that combat.

Relic Synergy

• Strange Spoon becomes helpful here, as it allows you to discard a card that otherwise might be exhausted (removed from your deck for the combat).
• Dolly's Mirror lets you duplicate a copy of a card in your deck on pickup.  Purchased as the merchant, so you can buy this (if possible) after the event to gain another apparition card.

Card Synergy

• Secret Technique card lets you pull a Skill from your draw pile and put it in your hand.  The upgraded version of this colorless card does not exhaust, so it can be used multiple times.  The card lets you pull an Apparition card from your draw pile in case you didn't have one in your hand.
• Exhume [ IronClad] card lets you place a card from your Exhaust pile into your hand.  It then exhausts.
• Echo Form [Defect] card makes the first card you play be played twice.  Since Intangible is a buff that stacks, doing so effectively gives you two intangible for the price of one card each round you play it as the first card.  This alone can lengthen the duration you can extend the 1 HP damage cap from any source.

Strategies

• Adding more cards into your hand.
• Use Nightmare [Silent] card, which will let you add three (3) copies of the card to your hand the next round you use it.  Its a skill and is not exhausted on use, so you can use Nightmware again to repeat the effect.
• Use Dual Wield [Iron Clad] card, which will add a copy (or two if upgraded) into your hand that turn.  Its a skill and is not exhausted on use, so you can use Dual Wield again to repeat the effect.
• Employ them with an all out attack deck.  This kind of deck focuses purely on attack, so you can dump, replace or remove defense cards and focus only on attacks.  The apparition cards let you drop any HP damage to 1 HP, including from effects.  The limit is you only have 5 cards (unless you make more), so turns have to be carefully counted and monitored.
