Reality vs Mental Damage — The Two Damage Types Explained

In Reverse: 1999, damage does not come in a single flavour. Every damaging Incantation (spell) and Ultimate is tagged as one of two types:

• Reality damage — physical, force-based harm. Think blades, bullets, storms, and raw impact.
• Mental damage — psychological and arcane harm. Think fear, mind-tricks, curses, and stress inflicted on the target.

An Arcanist's damage type is fixed by their kit — you can read it on the character's skill descriptions. Most damage dealers commit almost entirely to one type, so an Arcanist is usually spoken of as a Reality DPS or a Mental DPS. A handful of characters mix both, but treat mixed dealers as the exception, not the plan.

Importantly, damage type is a separate axis from Afflatus (the Beast/Plant/Star/Mineral four-way cycle — Spirit and Intellect stand outside it). Afflatus decides who gets a matchup bonus against whom; damage type decides which defense pool your hits are chewing through. A fight can punish you on both axes at once, so keep the two ideas separate in your head.

Here is the core mechanic. Enemies do not have one defense stat — they resist Reality and Mental independently. A boss can be a stone wall against Reality attacks while its mind stays wide open to Mental pressure, or the reverse.

That means your damage type is only as good as the wall it is hitting:

• Fire Reality damage into a target with low Reality defense and it lands hard.
• Fire that same Reality damage into a target with high Reality defense and much of it is soaked up — the fight drags, your Survival unit runs out of healing, and you risk timing out.

So the question is never just "who is my strongest DPS?" It is "which of my DPS attacks the type this enemy defends worst?" A mid-tier Mental dealer swinging at an enemy with paper-thin Mental defense will out-damage a top-tier Reality dealer beating on a Reality-armoured boss. Let the enemy pick your DPS for you.

You do not have to guess. Before locking your team, gather the enemy's defensive profile:

• Check the stage/enemy info. Many game modes preview the enemy's resistances or telegraph a defense type, so you can scout before the first turn.
• Watch your own numbers. If your damage feels muted against a wall you expected to break, that is the game telling you the enemy is defending your type. Swap to your other-type DPS and compare.
• Keep one dealer of each type levelled. The single best insurance against a hard wall is having both a Reality DPS and a Mental DPS built up, so you are never forced to grind through a resistance you can simply route around.

Combine this with the standard team backbone — 1 DPS + 1 Survival (healer or shielder) + 1 Support — and you swap only the DPS slot to answer the enemy, while your sustain and support core stays intact.

Damage type is the first filter, but it is not the whole picture. Once you have chosen the right-type DPS, stack every other edge on top:

• Afflatus matchup. If your correct-type DPS also holds the winning Afflatus against the enemy, you land extra damage on top of hitting the softer defense — the ideal case.
• Support that speaks your type. Pick a Support whose buffs amplify your DPS's damage type or debuff the enemy's matching defense, so the whole team pushes in one direction.
• Psychubes and Resonance. Tune your DPS toward its own damage type — a Psychube (equipment) that boosts the right stat and a Resonance (tuning) build that reinforces it turn a good matchup into a blowout. Build your Survival unit for sustain and your Support for utility; don't spread damage tuning across the whole team.

The habit to build: enemy defense first, Afflatus second, buffs third. Get the damage type right and every other investment pays off; get it wrong and no amount of Psychube tuning saves the run.

Knowing the formula explains why the same +30% can mean very different things. Damage resolves in this exact order:

DMG = (Final ATK − target Final DEF) × Penetration Rate × DEF Reduction × Critical DMG × DMG Bonus × Incantation/Ultimate Might × Skill Multiplier × Afflatus Advantage

The key point: these sit in separate multiplier buckets. Adding 30% to an empty bucket is worth far more than stacking it onto one that is already high — which is why a balanced build usually beats an all-in one.

If the enemy's defense is high enough that (ATK − DEF) drops to 0 or below, the hit still lands for at least 10% of your Final ATK. There is no state where an attack does literally nothing.

What this means in practice: against a very tanky target, piling on more ATK barely helps — what you actually need is Penetration, DEF Reduction, or a switch to Genesis DMG, which ignores defense entirely.

Alongside the Reality/Mental damage axis, Reverse: 1999 also has a card (Incantation) layer you interact with every turn:

• 6 card types exist in the game, each with its own color for quick recognition in hand. Their control-based counters reveal which types they are: [Disarm] blocks Attack-type cards, while [Silence] blocks all four of Buff, Debuff, Heal, and Counter — 5 of the 6 types are exposed just through how they get shut down.
• Cards have tiers 1-3. Merging two cards of the same type and same tier upgrades them into a higher tier. The twist: upgrading can change the card's type entirely — a tier-1 Buff card is not guaranteed to stay a Buff after merging; it can turn into something else depending on the character's kit.
• You can preview the enemy's card. Before your turn, the battle UI shows what type and tier the enemy is about to cast — use that to decide whether to block/heal through it or burst them down before it lands.

Combine this card layer with the Reality/Mental damage-type layer above: you pick the right DPS based on enemy defense, and read the enemy's upcoming card to dodge or counter at the right moment — stacking both layers of information is what makes for an optimal turn.
