Not only are brandishes underpowered, but also your friendly neighbor Gran Faust! Why?

In PvE, Gran Faust:
Cannot 1HKO Snarbolax
Cannot 1HKO Royal Jelly
Cannot 1HKO Roarmulus Twins
Cannot 1HKO Vanaduke
Cannot 1HKO Trojan
Cannot 1HKO Tortodrone
Cannot 1HKO Seerus
Cannot 1HKO a stone block
Cannot 1HKO an elevator

In PvP, Gran Faust:
Does not have 99.9% chance of cursing on first hit
Does not have 24 tiles range
Does not deal 3333 damage per hit
Does not drop hearts with every hit
Does not have a brandish charge
Does not have a FF speed
Does not have a WRH range

Most blasphemously:
GF is usable without ASI
ASI only makes GF swings faster, no other effects. How unfair to those who dumped $1000 for ASI VH

How to balance?

GF should be able to 1HKO any monster. If the monster is a boss, proceed to the prizebox area behind; get 10x token if the killing hit is scored a GF. If the monster is not a boss, show 9986 damage for every hit; sound effect becomes "It's super effective!"
GF ignore Trojan shield, Mecha Knight shield and Roarmulus Shield.
GF should 3x range and 3x damage

Give GF the following abilities in Lockdown:
Range
Passive: GF's range increases by 8/16/32/64/128 tiles every time it scores a second hit.
Active: GF does a 720 degree spin, knocking all enemies within 365 tiles range away, dealing 10 second of stun and 666/777/888/999/1111 shadow damage.
Cooldown: 8 seconds

Curse
Passive: GF's chance to curse increases by 49% every time it scores a first hit. Base chance is 50.99999%
Active: GF curses everyone within 365 tiles range; those cursed receive ASI VVVVVH bonus but must keep on attacking until their HP reaches -27 bars.
Cooldown: 16 seconds

For ASI VH GFs, add following skill:
Speed
Passive: GF's speed increases by 10/12/14/16/18% every time it hits with its first hit
Active: GF uses an insulin-boosted swipe, interrupting all enemy attacks for 10 seconds within 364 tiles range, and deals 6666/7777/8888/9999/11111 shadow damage.
Cooldown: 12 seconds
