Direct Attack

Direct Attack ダイレクトアタック (Dairekuto Atakku)

DM-Wiki:	Article

Direct Attack is the term for the final attack of one of your creatures against your opponent who has no shields.

Details

An opponent player fails to defend against this loses the game.

It is the one of the most basic victory conditions of Duel Masters.

If your opponent has at least one shield, the direct attack can't be done.

For example, if you attack your opponent while they control a shield by a creature that has Double Breaker, only one shield is broken and the direct attack doesn't occur

If you can destroy the attacking creature by blocking with Blocker or a Ninja Strike ability, you can stop direct attacks.
Some cards can prevent your opponent from winning the game even by a direct attack for a turn, such as Diehard Ryusei of Invincibility and Oni "Champion", Victory Twelve.
The Revolution 0 Trigger ability can only be triggered at this point.
When you attack a player with Spectryte, Crystal Gaia or Royal Straight Flush Kaiser, if you can trigger their ability to reduce the number of shields to 0, the attack by them will be direct.
Alternate Wins to a direct attack can also include reducing the number of cards in your opponents deck to 0, so they may satisfy an special defeat condition.
Many players declare とどめ (Todome) as they announce they are attacking their opponent directly due to the Duel Masters anime. Some players refer to it as "player attack" or "checkmate".

509. Direct Attack Step
- 509.1. If the attacking creature was declared to attack the nonactive player and the attack was not redirected, the attack is considered a direct attack. If the nonactive player has no shields left, that player loses the game. This is a state-based action.
- 509.2. Choose which shields the creature that attacked directly will break.
  - 509.2a Creatures break one shield by default.
  - 509.2b A creature may have the ability to break multiple shields (such as Double Breaker). In that case, break the number of shields specified by that ability.
  - 509.2c If the attacking creature has multiple breaker abilities simultaneously, its owner chooses which one of them is applied. If any breaker abilities are present, one of them must be applied.
- 509.3. The attacking creature breaks the chosen shields simultaneously. Even if the number is less than the one speficied by a possible breaker ability and new shields would be added due to some effect after the decision, those new shields cannot be chosen.
  - 509.3a When a shield is broken and is put into a player's hand, if it has Shield trigger ability, that player can declare to use that ability. If multiple shields with Shield Trigger ability are put into a player's hand this way, that player declares the usage of those Shield Trigger abilities simultaneously.
  - 509.3b If a player whose shields are broken has cards with Strike Back abilities in their hand, those abilities can be declared by discarding the cards that are put into that player's hand. The declared cards must be revealed to each player.
  - 509.3c When the declaration is over, the broken shields are added to their owner's hand. After that, the declared Shield trigger and Strike Back abilities are resolved in any order.
- 509.4. Even if an ability allows to break multiple shields simultaneously, it is not possible to choose the same shield twice. If a chosen shield is not broken in some way, it stays in the shield zone.
