Lies of P: Capacity Explained
An initially odd stat, Capacity doesn’t determine how much you can carry but rather how much Weight you can have equipped at any given time. The more Capacity you have, the heavier (and more powerful) weapons, armor/amulets, and Legion Arms you’ll be able to have equipped without suffering a movement penalty. Capacity also increases your Legion meter as well as your Physical, Fire, Electric Blitz, and Acid defenses.
Lies of P: Motivity Explained
One of the more confusing stats in the game, Motivity increases your overall Attack Power but is primarily designed to scale with heavier weaponry. If you’re planning on wielding heavier weapons, you’ll want more Motivity. It also increases your Physical, Fire, Electric Blitz, and Acid defenses.
Lies of P: Technique Explained
Like Motivity, Technique increases your overall Attack Power. However, Technique most commonly scales with lighter, quicker weapons whereas Motivity more often scales with heavier weapons. It also increases your Physical, Fire, Electric Blitz, and Acid defenses.
Lies of P: Advance Explained
Advance will also increase your Attack Power, but it primarily impacts the Attack Power of your Legion Arms as well as weapons that scale with Advance (which are primarily elementally enhanced pieces of gear). To compensate for that specificity, Advance also increases your Legion and your defenses against Disruption, Shock, and Break effects.
Lies of P: Common and Defensive Stats
While the above stats are the only ones you can directly invest points into in Lies of P, leveling those stats will often increase a series of Common and Defensive stats associated with your character. Here is what all of those stats determine:
HP
As you probably suspected, HP simply determines your maximum number of Hit Points and the size of your health bar. Though that obviously indirectly impacts your defenses, higher HP does not directly make you more resilient to various forms of attack.
