Stat Stick Passives

Support cards will either be used for their skills or as stat sticks. Comparing skills is easy, but comparing their ability to be a stat stick is more complicated.

Let’s look at what’s widely considered the best support card in the game, Kitasan Black, at max limit break.

Typically the passives you’ll be interested in for a stat stick are “Friendship Bonus,” “Training Effectiveness,” “Mood Effect,” “<stat> Bonus” and “Specialty Priority.” “Initial Friendship Gauge” is also convenient as it reduces the time taken to get them to orange bond.

The Mood Effect is added to the bonus you get from your current mood, which is +/- 10% per deviation from normal. So, with max mood, it’s +20%. With Kitasan’s +30% Mood Effect, this gets to +26%. This also applies negatively, so if you’re at bottom mood, it would go from -20% to -26%.

Training Effectiveness and Friendship Bonus work multiplicatively with this. For unique skills, mood effect and training effectiveness are additive, while friendship bonus is multiplicative. She has a 5% training effectiveness from her unique skill, 10% training effectiveness, and 25% friendship effectiveness. All together, the stat gains will be multiplied by 1.26 * 1.15 * 1.25 for a total of +81% stats from these passives. Note that friendship and unique friendship will act multiplicatively with each other, not additively. A card with 25% Friendship Bonus and 10% unique friendship bonus will give you 37.5%, not 35%.

Specialty Priority increases how often the card will land on its preferred training. Specialty adds to the weight, while specialty from the uniques multiplies it as if a percent, the same way Friendship Bonus works. Each stat has a base weight of 100, and not appearing has a weight of 50. These are divided by the total to give the chance of appearing on each training, so 100/550 = 18.18% rainbow rate with 0 specialty. For Kitasan, she has 80 base, so 100 + 80 = 180, then she has unique specialty, so 180 * 1.2 = 216, which is the same as having 116 base. Her Speed appearance rate would be 216/666, or 32.4%. (Theoretically, slightly lower due to the chance of the training being full?)

<Stat> Bonus effects, like Kitasan’s Power Bonus, add 1 to how much the training will give you of that stat, before all the modifiers. Kitasan’s is Power rather than Speed, which means your big speed rainbows will also give a lot of power. This will also apply when she appears on Power or Guts trainings.
