Blood Rage

Blood Rage is a new gameplay system in God Eater 2 Rage Burst for the Protagonist (God Eater 2) only, the system is a "final power-up mode" superior to even the Level 3 Link-Burst. As a result, this powerup can only be used once or twice in certain missions, after a certain percentage of an "Enemy Meter" from fighting against an Aragami is filled to 100%. The player can then access a touch-screen menu of blade-shaped tabs that list a certain weapon damage percentage increase. They can select one or more of several specific conditions that must be chosen and fufilled in order to gain a specific weapon damage increase and the activation of the Blood Rage power-up. Should one of the tab options be chosen, that condition, and any other condition selected, must be fulfilled within 30 seconds in order to gain that chosen tab's damage increase percentage and for the successful activation of Blood Rage. Failure to complete the selected conditions will eat 100% of the meter. The Blood Rage build-up meter can store up to 400% (in four stacks of 100%) and can be used for future missions. The meter can be filled by attacking Aragami (does not work with dead Aragami but the meter will fill up slowly by it's own).

When Blood Rage activates, it will last 30 seconds (the power-up's remaining time is shown at the bottom left corner of the screen). Aesthetic changes in Blood Rage include a yellow semi-circle wing with spiky structure on the player character's back, leaving a black and yellow stream of (presumably) Oracle Cells. When idle, the stream circles around the player's back and when moving around, it trails them. Also, a new song titled "Blood Rage" starts immediately when Blood Rage is activated. These effects, including the damage increase, disappear by the end of Blood Rage's duration.

Blood Rage lasts for a short time and while it does, certain effects are applied to the player character. The main aspect of Blood Rage is the significant increase in damage that can be gained, with a potential 400% increase being possible. Additionally, while in Blood Rage, the player character is impervious to enemy attacks, can shoot regular Oracle bullets infinitely (recovery bullets do consume OP normally), can ground-step/roll infinitely without delay, and devouring speed is increased as well (not to be mistaken for the charge-up time, which is already affected by a separate skill, but whenever a Devour Attack connects).

With the Short Blade equipped in Blood Rage, one can also air-dash 3 times in a row. Blood Rage can be activated in both Gun form and Blade form, and sometimes the Blood Rage activation conditions can contain a restriction on usage of a certain form's regular attacks (ex: all Blade form attacks except shield-cancel Devour attack are unusable until Blood Rage is activated).

Miscellaneous

 * Burst can be active at the same time as Blood Rage.
 * Blood Rage does not stop your Burst meter.
 * Your teammates can help you fulfill the conditions.
 * It's much easier to fulfill the condition when other players have achieved Blood Rage.
 * All Stamina-using actions won't consume any Stamina while in Blood Rage.
 * Blood Rage also grants additional reduction for OP consumption. The more vows you take, adding to the modifiers' total percentage, the less OP a bullet requires to shoot once you activate Blood Rage.
 * If the Blood Rage end during Boost Rush, you can continue doing it without needing to activate Boost again.
 * If you use a Blood Art that consume the whole Stamina, you will not enter "out of breath" state.
