Command Cards

Command Cards are used to attack enemies during Battle. There are three different types: Quick, Arts, and Buster. Five of these are chosen at random from your Command Deck, and you are allowed to use three of these during each Command Phase.

After 3 turns, where all 15 cards from Command Deck are used up, the cards are shuffled again.

Cards in the Command Deck are shuffled if one or more Servants that you control are defeated. Cards can also be manually shuffled by using Master Skills.

Chains
Quick, Arts, and Buster chains occur when 3 of that card type are selected. Brave Chains occur when 3 cards are chosen that belong to the same servant.
 * Quick Chain - Gain 10 Critical Stars for the next Command Phase.
 * Arts Chain - Increases NP Gauge by 20% for servants in the chain.
 * Buster Chain - Attacks do 20% bonus damage this turn.
 * Brave Chain - Perform an additional attack for 200% bonus damage, or 350% if it's also a Quick, Arts, or Buster chain.

First Card Bonus
The first Command Card you choose gives all cards a bonus depending on type.
 * Quick -Plus 20% to crit star rate.
 * Arts - Plus 100% to NP gauge rate.
 * Buster - Plus 50% to Damage
 * Noble Phantasms are not affected by card order placement (1,2 or 3) or the first card bonus.
 * The Actual Damage done by the noble phantasm is based on the card type. The damage of the noble phantasm is multiplied by the value in the table (1st column), 80% (0.8) for quick card noble phantasms, 100% (1.0) for arts, 150% (1.5) for buster.
 * For example, Sasaki Kojirou's Noble Phantasm at level 1 deals 1200%. Since this Noble Phantasm is a Quick card, the actual damage done is multiplied by 0.8, 1200 * 0.8 = 960%
 * Artoria Pendragon's Noble Phantasm at level 1 deals 300% (pre-interlude). Since this is Buster card the actual damage done is multiplied by 1.5, hence 300 * 1.5 = 450%
