When struck by a Basic Attack while Unstoppable, or when Shocked, Frank gains a non-stacking Rage Debuff for -1 seconds. With Rage, Frank’s Basic Attack hits Passively convert a flat 10.0% more Adrenaline to Health.

Frank does not idle after Dodging back, and gains an Unstoppable Passive for 0.7 seconds when he starts to run. This will not re-trigger while active, and is paused while running, charging Heavy Attacks, or attacking.
Frank’s Unstoppable also grants him +30.0% Combat Adrenaline, and it prevents incoming Basic Attacks from resetting his Combo Meter. As an Attacker, it also grants him Stun Immunity.
As an Attacker, Frank also gains his Unstoppable when he is struck by a Basic Attack immediately after Dodging back. He also gains it, plus the ability to run immediately, after Blocking the final hit of the Opponent’s Special Attacks.
This Unstoppable is immediately removed at the end of Frank’s Heavy or Special Attacks, and when the Opponent activates a Special Attack.

CRUSHING BLOWS — DURING FRANK'S UNSTOPPABLE▾

On hit or on Block as an Attacker, Frank’s second Basic Attack inflicts an indefinite Crush Passive until his Unstoppable expires.
When Frank’s Crush ends after being used to Break a Block, it goes on cooldown for 20 seconds, or until he gains 100.0 of his Berserk Passives.

EXTERNAL COMBUSTION — HEAVY ATTACK▾

On hit, Frank’s Heavy Attack inflicts an Incinerate Debuff that deals 70.0 Energy Damage over 20 seconds, paused during his Special Attacks. Max stacks: -1.
On hit or Block, Frank’s Heavy Attack also adds 400.0 hits to his Combo Meter.

SPECIAL ATTACK 2▾

The first -1 hits each grant Frank a personal Berserk Passive.
The final hit refreshes all of Frank’s Incinerates, and then inflicts -1 Incinerate Debuffs that each deal 70.0 Energy Damage over 30 seconds, paused during his Special Attacks. Max stacks: -1.

SPECIAL ATTACK 3▾

Frank gains 15.0% of missing Health as Adrenaline, and Passively Stuns the Opponent for -1 seconds.
