Being the strongest of the 5th Generation, Labrys's fighting capabilities are far above average and were only strengthened when she gained a Persona. Using her multi-use weapon, a giant axe that she is strong enough to swing with ease, she can easily do massive damage to any opponent she comes across. Upon awakening her Persona, Ariadne, she can use Weaver Arts to create weapons out of nothing and provide even more options to defeat her foes.
The Axe-Gauge grants her buffs max 5 levels based on the colors, depending on how often you attack with moves that utilize Labrys' axe (this includes blocked attacks). However, it will slowly decrease if you don't attack and decreases even more if you get hit or do not attack with a move that swings the axe. The levels are broken down into the following colors with 1 being the lowest, 5 being the highest: No Color/Gray > Blue > Green > Yellow > Red. The higher the level of the Axe Gauge is, the more damage she does. Once you reach her red axe level, she gains the following special properties in addition to extra damage: Under Red Axe, Labrys also does significantly more chip damage when in Resonance Blaze, through all of her normals and specials, including non-axe normals. These are the tips how to manage her levels increase and decrease and other factors to note when playing as Labrys.
At the start of each match, the axe gauge starts at level 3 (Green).
Getting hit will cause the axe meter to deplete, and can even go down to level 2(blue) and can completely empty out the gauge, bringing it to level 1 (gray)
The axe gauge will always drift to a level 3 (green) status, so even from maximum axe meter (glowing red axe bar) you will slowly lose axe meter until it gets to green as long as you're not hitting the opponent
Using certain special moves will build the gauge faster then normal moves such as Guillotine Axe.
Persona normals such as 2B and 5B will not build axe meter
Both of Labrys' supers will cause her axe gauge to deplete (except when she does the tag version of her super after her partner)
Labrys loses axe meter while tagged out, but this can be slowed by using her 4P and 5P, both of which build small amounts of axe meter on hit/block
Labrys' Axe management is not as much of an issue as it was in the Arena games. Labrys has several routes both with and without assists to go from green-to-red that also double as giving her air guillotine enders which allow her to also get good okizeme.
