WARNING - LONG POST

As the title says, this would be a special badge that one wears to signify their specialization toward a specific or all weapons. There would be 4 different badges; Swordsman, Gunslinger, Bomber, All Rounder. Each of with enhance a player's ability with said weapon by giving it an ability/skill (or a small advantage with all weapons in the all rounder's case). However, each badge cannot be upgraded and you must complete a special quest in order to receive the badge. (Gotta earn it, not buy it). Only 1 badge can be worn at a time. Also one does not have to be using 4 swords to wear the sword badge, however, 4 swords is needed to earn the badge in the first place.

Here are my ideas on how they'd work,

Swordsman Badge
Skill acquired: Sheath block (Passive) - As most swords have a sheath this would give a knight the "chance" of blocking incoming attacks. The would obviously be a cooldown that prevent's successive blocks. But I feel that is is a reasonable thing for swordies since they're up close and personal most of the time. Only works if a sword is the current item is use.

How to get: Complete FSC from the beginning of depth 24 to the core with an arsenal of 4 Five-star swords.

Gunslinger Badge
Skill acquired: Silencer (Passive)- Bullets become slightly silenced leaving them unnoticeable to enemies. Basically no more dodging wolvers/fiends. Only useable with guns, swords don't get silenced.

How to get: Same as sword badge but with guns

Bomber Badge
Skill acquired: Remote detonation (Active)- While charging, with a special action key is pressed then the remote detonator will be set with your bomb. This gives bombs the ability to be detonated from afar. Fuse times will still apply as the bomb cannot be detonated until after the fuse (or maybe we can make it so that when the detonate button is pushed, then fuse starts). Downside is that no other bomb can be placed while there is a undetonated bomb on the field, leaving knights vulnerable (Shielding, however, is still permitted).

How to get: You can probably guess the pattern.

All Rounder Badge
Skill acquired: Advantage shift (Passive - Able to toggle) - With this badge equipped players will receive an extra elemental/pierce/shadow/norm damage UV to all weapons. The same UV will be applied to all weapons in the current arsenal. However, a player can change the damage type to any that he/she sees fit at a arsenal station.

How to get: Dauntless Delve (depth 0 - core with no deaths) with a arsenal consisting of at least 1 sword, 1 gun, 1 bomb. All of which must be 5 star.

The reason I want this idea is because it gives a bonus to players who specialize with certain weapons. It, in a way, mimics having a job class, but not really.
Feel free to comment and leave your ideas as I know there could be ways that things could be improved/abused. Like how its unfair that bombers get an active skill while others get passive, etc. I also understand that since you hold a shield, you can also hold a sheath... I couldn't come up with another idea. LOL its only a suggestion :/
