Amputator
Known as the Normal damage type Brandish it has a unique property to flinch enemies with the charged attack's AoE strikes, something that no other Brandish in the game can do. It's rather unique, most people who use Brandishes such as Acheron, Obsidian Edge, Combuster, Glacius or Voltedge do not typically expect the AoE attacks to flinch enemies. However it suffers from a feature which has left a decade in the past, which is its Family Bonus. This results in it dealing less damage overall while failing to even specialize against the family it has a hypothetical advantage against which are Jellies.
To tackle this problem, the simple solution would be to remove the Damage VS Jelly: High and compensate with additional base attack. This will simply make the Sword stronger than before without it attempting to specialize against a super-specific enemy type (which it should) on top of keeping its identity as the "Normal damage Brandish".
Flourishes
I know I made a point before about them already, however I want to address Flourishes once more with the recent Weapon Adjustment Round on the horizon. Currently, post-preview Wild Hunting Blade outperforms Flourishes by a long shot to the point where the competition is not even remotely close. Wild Hunting Blade is simply miles stronger, as it mows down enemies like no tomorrow.
For Flourishes, their actions should be quickened across the board. The recovery should be cut by a few frames for their third Basic Attack and their Charged Attack. Start-up should be decently reduced on Charged Attack and its charge time required should be changed so its equal to Dread Venom Striker's. Knockback on first Basic Attack should be halved to allow easier follow-ups. Piercing damage should be greatly increased so it is not outdamaged by Swords such as Acheron within Tier 3. Hitbox on second, third Basic Attacks should be extended horizontally to allow the weapons to reach enemies without relying on Auto-Target's inconsistent targetting. This will make the Flourishes worthy of their title as a fast Sword and while not able to dish out the same damage-per-second as Wild Hunting Blade they will serve as a safer, more reliable option to use in order to engage enemies with.
Fang Of Vog
Probably one of the most unique weapons in the game, Fang of Vog (FoV) is a weapon which has a Basic Attack similar to a Calibur/Brandish but is slower and can inflict Strong Fire with its Charged Attack and its Basic Attacks. Its Charged Attack is near identical to a Calibur too, as it performs a 360 degree spin and hits up to four times unlike three of Calibur while having the potential chance to set your character on Fire. Its potential is incredible... unfortunately a majority of the time it's preferable not to bring it with you as its self-Fire (much like Gran Faust's self Curse) can be a massive liability for the one using it. On top of that, it's safer to bring a Combuster as it has near-identical offensive performance, while also with the benefit of not setting you on Strong Fire.
Much like Gran Faust, the reward should be raised for the risk you are taking. Increase the damage dealt by the Charged Attack by 100%, doing so will make it a more reliable option for dealing extreme amounts of damage in a quick burst, ensuring the wielder takes down most enemies with a single Charge Attack. Additionally, its increased damage will make its bursts more reliable in parties and reach damage thresholds it could not before.
