For those that don't know, I will transcribe the rules of Tetra Master, sourced from various sources, mostly the FF Wiki and the people that fandom stole it from
The numbers on the cards are the ranges that the actual number can be. THe actual number it can be is between 0 and 255
3-P-6-0
This card's Power is 3 (from 0-F)
This card's Type is Physical
(from Physical, Magical, fleXible, or Assault)
This card's Physical Defense is 6 (from 0-F)
This card's Magic Defense is 0 (From 0-F)
The arrows represent the directions it can attach there. Pink Pudge can only attack to the Left or Right. The defender's arrows are not called into play, only the attackers' arrow
Physical Attack: The Power of the attacker is compared to the Physical Defense of the defender
Magical Attack: The power of the attacker is compared to the Magical Defense of the defender
Flexible: The power of the attacker is compared to the Physical or Magical Defense of the defending card, whichever is weaker
Assault: The Power, pDEF, or mDEF of the attacker (whichever is highest) is compared to the Power, pDEF, or mDEF of the defending card (Whichever is weaker)
In every case, when numbers are needed to be referenced, the number on the card is a very specific subset of numbers:
0 is 000-015
2 is 032-047
7 is 112-127
9 is 144-159, etc
All the wayt up to F being 240-255
in a tetra master fight:
5P33 (Card A) attacks 2M10 (Card B)
Step 1: Determine maximum power. (5 = between 80 and 95. 85 is rolled)
Step 2: Determine maximum defense (P, so physical, so 1 - between 16 and 31. 23 is rolled.)
Step 3: Determine actual power. A random number between 0 and [Step 1] is rolled. 71.
Step 4: Determine actual defense. A random number between 0 and [Step 2] is rolled. 3.
Step 5: Math. Subtract Step 3/4 from Step 1/2.
Card A: 85 - 71 = 14.
Card B: 23 - 3 = 20
Card B (2M10) wins the fight against Card A (5P33)
