Under Night In-Birth/System
GRD System
The GRD ("Grind Grid") system is a very unique aspect to Under Night In-Birth, and a very important factor in the game.
The GRD is a tug of war that plays during the rounds of combat. Each character owns six squares on the GRD which they can attempt to fill by being aggressive, recovering/teching, shielding attacks, and using concentration. The GRD is lowered by back dashing, taking damage, using File:UNI B.gif + File:UNI C.gif, getting shield blocked, throws getting escaped, and opponents using Concentration.
A timer shows itself as a repeating circle of progress in the middle of the GRD bar. It takes 16.5 in-game seconds to complete so it repeats exactly 6 times in a 99 second round. When the progress bar is filled, the character with the most amount of filled squares will enter a state called GRD Vorpal, which provides a 10% damage boost to the favored character.
When using Chain Shift, the GRD is absorbed and transformed into EXS at a rate of 20 meter per box (up to 120 meter), at the cost of resetting the GRD to zero.
EXS System
The EXS System is quite simply the super meter, which uniquely is measured in large percentages; starting at 0.00, and going all the way to 200.00. Each character has two stocks (or halves if you will) to their EXS meter; the first stock is filled at 100.00, and the second stock is filled at 200.00
In battle, the EXS meter is filled up accordingly to damage that is taken and dealt, just like any good old fighting game super meter, which is bolstered by being in Vorpal. EXS can also be filled by using Chain Shift, which converts GRD into EXS.
EXS is used for the EX version of Special Moves, Infinite Worths, Guard Thrusts, Assault, and Veil Off.

Supers
Most specials have a super version, performed by using the C button rather than A or B. Supers take 100 meter or 1/3 of the bar during Veil Off.
Infinite Worth
Infinite Worth refers to a character's ultimate super attacks. The normal version of Infinite Worth can be performed with 41236D when your meter is maxed at 200. Infinite Worth EXS is an even more powerful move with invincible startup that can be performed with A+B+C+D during one of two conditions: 1. At max meter with your HP under 30%. Using it this way will result in GRD break status. 2. While in Veil Off mode. This method immediately ends Veil Off mode but does not result in GRD break.
Button Priority
