Brandishes-
-Normal hits deal pure normal damage equal to leviathan blade
-Charged hit deals pure normal damage equal to leviathan blade charge
-Charged explosions deal elemental or shadow
Divine avenger / Gran Faust would follow suit
-Normal hits deal normal damage
-Normal charge hit
-Elemental or shadow charge projectiles
Fang of Vog
-all attacks are pure elemental
Flourishes-
-First hit (the swipe) deals normal damage
Why we think this would be healthy for the game
When the game first came out the meta was basically leviathan blade and divine avenger/gran faust.
This was because there were no arsenal stations, so leviathan blade hit hard on status stratums, where a sword like final flourish might encounter an entire depth of construct rendering it useless. Divine Avenger/Gran Faust on the other hand had split damage, allowing them to deal good damage against most things and incredible damage when powered up.
The brandishes entered the scene later when their charge was buffed to be reliable- instead of doing 2-5 charges they just always did 5. Meanwhile, divine avenger's charge got hit with a nerf, making it get stuck on everything nearby and dissipating to avoid cheesing levels like FSC.
These were all good changes, though they took away from what the game originally was about- preparing for a wide variety of situations. Zeddy's suggested changes hope to address this concern and reel back on the power that split damage presents.
Personally I like these changes because of how strong swords are for how little effort they take to use when starting out. When swords deal normal they become more of a utility and less of a crutch. You can still rely on them, they still do their job, but they aren't so powerful that you give up on crafting a variety of weapons just to have a brandish/flourish going.
Yo, not everybody plays a charge oriented gameplay, people actually use the normal attacks on swords in case you didn't know. I find this suggestion interesting yet very horrible. A better idea would be to make two thirds normal damage and one third the other type but the explosions/projectiles would be pure non-normal, except for the flourishes which would stay piercing on all attacks, a lot of people use this sword for ONLY the first swipe. Fang of Vog would still have normal damage as well, making it pure elemental doesn't make sense. This would make swords better at what they do while making guns and bombs more viable due to their pure damage. Also a buff to Levinthian blade to match up to Acheron's damage would be so good to make it actually have a use since after these changes Acheron would just be way better at dealing damage to everything except slimes and gremlins. Although I'm a fan of using regular attacks, combos and rarely use charges except with Voltedge and I think this would hurt my playstyle, it's what should be done for the game balance IMO. But of that was to be done it can actually hurt lockdown amd forcing it into a pure Final Flourish and gum meta without using split damage swords at all since they'd do very little damage compared to before, some people would use Warmaster Rocket Hammer instead but not all people have luck rolling om it which can be somewhat unfair. And believe me when I say you DON'T want a whole lockdown lobby using Warmaster Rocket Hammer. It'd just be too annoying especially for the newer/higher-ping players. So yeah your suggestion is looking into making the whole sword role in PvE is using charge attacks while making them near completely useless in lockdown while my suggestion is looking into making them a bit more charge oriented without hurting them much but they'll also suffer in lockdown. So I propose another third suggestion, keep them as they are, this wouldn't make PvP solely charge-oriented and people wouldn't just use guns everywhere instead of swords and lockdown people will still use split damage swords. Sorry for the long post and thank you for reading it to the end. You should think about what you write before posting it and how it would affect the game and the players, your playstyle isn't the only one or other people's you know there is still a lot to learn.
