The Command Deck is, in short, your Abilities, your Skills, and your Spells. Every character is capable of using these.
As time goes on and your character grows stronger, they will gain access to more Spells, Skills, and Abilities.
0-5k Willpower/Potential = 3 skills, 3 spells
3k-7k Willpower/Potential = 6 skills, 6 spells
7k-11k Willpower/Potential = 9 skills, 9 spells
11k-16k Willpower/Potential = 12 skills, 12 spells
16k-21k Willpower/Potential = 15 skills, 15 spells
21-27k Willpower/Potential = 18 skills, 18 spells
27k-35k Willpower/Potential = 20 skills, 20 spells
Level 1: 1 Stamina or Mana, 35% Damage (charges in increments of 20% up to a maximum of 95% Potential)
Level 2: 2 Stamina or Mana, 60% (charges in increments of 20% up to a maximum of 100% Potential)
Level 3: 3 Stamina or Mana, 100% (Does not charge but damage can be increased by things such as Fire Boost, or by Command Styles)
Level 4: 3 Stamina or Mana, 50% your Potential and 50% of a friend's Potential! (Charges in increments of 25%, making the total out to be 200%)
SHOTLOCK: 35% for 1 Mana and Stamina, 60% for 2 Mana and Stamina, 100% for 3 Mana and Stamina. Shotlocks cannot miss.
Things worth noting:-Every 10k Willpower/Potential grants you an additional ability slot.
-Levels 1-3 are Skills and Spells that your character can use alone, and they work entirely off of your Potential, which is your offensive stat.
-The hard cap on Level 3/4 Skills and Spells is 100%.
-Level 4 Skills and Spells are special; they are combination attacks. You need to have one person that can use Level 4 as well.
The process of learning a new spell or skill is done over time. Keep a list of unlearned skills that you want to learn on your profile and they will be given to you when you are graded provided you have an open slot and have proven yourself capable of knowing it. That being said, please be sure to put down how many open slots you have and what your focus in combat is. Be it an elemental focus or a focus on physical (heavy or speedy) or magical skills (offensive or defensive). It helps the staff grant you your skills in such a way that doesn't go against your character's combat strategy.
