DDM Companion

🪄 What this is

This site is a reference for a Dungeon Dice Monsters (GBA) improvement patch. It's also a good reference for the base game, btw.

Some of what the patch does:

Speeds the game up, by a lot.
Makes the AI smarter & lets it use its monsters' abilities.
Adds a suspend feature.
Rolls twice, à la the paper game's "advanced" rules.
Adjusts the droprates to make the commons less common and rares less rare. The sale prices are reduced accordingly.
Adjusts the shop's unlock curve, such that non-grindy play is enough to unlock everything.
Lists 🎴D. Magician Girl in the shop once she's farmable.
Fixes various bugs.
You can have at most one of any die in your pool, so the best pool isn't just 🎴Time Wizards, 🎴Battle Warriors, & 🎴Energy Discs.

🎲 Reading a die

What the symbols used on this site mean.

We serve die previews. Try it: 🎴Dark Magician Dark Magician (ブラック・マジシャン) — level 4 — 3 hearts, attack 40, defense 20 — Spellcaster — faces Sum Atk Mov2 Def2 Tra Mag

Here is how the site templates the magician's properties: ♥♥♥ ⚔ 40 🛡 20 · Spellcaster · level 4 · SumAtkMov2Def2TraMag

One ♥ represents ten points of health, so three hearts correspond to the 30 health shown on the card.

⚔ is attack and 🛡 is defense. The family's graphic (e.g. for Spellcaster) is shown. In-game, that's all you get; here we also list the family's name.

A monster can have traits; the traits are flying, reach, and tunneling.

A roll can yield any of a die's six faces. Faces grant crests; the possible faces are as follows: Sum is a summon crest, Mov a move crest, Atk attack, Def guard, Mag magic and Tra trap. A face can grant multiple of its crest, like how the magician's Def2 face gives two guard crests.

A die's level runs from 1 to 4. A level 4 die has one summon crest. Each step down in level adds another summon crest, so, a level 1 will have four of them.

🎁 Getting dice

There are two-ish ways to get dice.

Winning a duel awards one die from among all of the dice that opponent could put in their pool. This includes ones that weren't in their pool that time.

Trading exists.

⚔ Combat

What happens when monsters fight?

Attacking costs an Atk and does the attacker's ⚔ in damage.

The defending team can do one of: wait and take the hit, spend a Def to guard (which takes the defender's 🛡 off the damage), or answer with an ability.

Dragon > Spellcaster > Undead > Beast > Warrior > Dragon

each > means "hits for 10 more and is hit for 10 less"

the few monsters with the ability no family pros or cons stand outside the cycle

Two monsters can use their effects on allied monsters that are under attack. These are 🎴Saggi the Dark Clown Saggi the Dark Clown (闇・道化師のサギー) — level 1 — 1 heart, attack 10, defense 10 — Spellcaster — faces Sum Sum Sum Sum Def Tra — Reduces damage to one ally by 10. — costs 2 defense and 🎴Dark-eyes Illusionist Dark-eyes Illusionist (ダーク・アイズ・イリュージョニスト) — level 4 — 1 heart, attack 10, defense 10 — Spellcaster — faces Sum Mov Atk2 Def2 Mag Tra3 — Negates attack & effect on 1 ally. — costs 5 trap .

🌟 Dark Magician Girl

Information about a rare monster.

🎴D. Magician Girl D. Magician Girl (ブラック・マジシャン・ガール) — level 3 — 2 hearts, attack 20, defense 10 — Spellcaster — faces Sum Sum Mov Tra Atk Def — Obtains ATK & DEF of all destroyed Spellcaster. (Dimension) is dropped by Yami Yugi. He's only around in the "postgame".

In the base game, she can't be bought in the shop. The shop interface has a "slot" where she "would" go, but nothing causes her to be listed there.

The patch raises her drop rate, and lists her in the shop once in the "postgame".
