I have a few ideas, written down on a paper somewhere.
Exotic sword
Lightsaber
Flavour text: ok I forgor but it was really cool I think
Exotic perk: blocking deflects all projectiles that directly hit the swords guard to where you are facing. Deflected bullets have decreased damage by 25%. (really low guard length however)
Intrinsic perk: getting kills with reflected bullets extends duration.
Catalyst: this weapon has a perk based on subclass (arc: voltshot. Solar: incandescent. Void: volatile rounds (idk tbh). Stasis: kills spread slow to nearby targets. Strand: I'm not sure.)
Also, the sabers colour is whatever subclass ur using, so goes really well with the solstice sets.
I forgor the lore as well it was really good I think...
Tl-50 heavy repeater
Machine gun
Flavour text: a veist remake of a weapon found in a distant galaxy.
[spoiler]from star wars battlefront[/spoiler]
Exotic perk: this weapon fires projectiles that are not hit scan. Charging this weapon up (533 ms) fires a slow moving projectile (similar to grand overture one but double the damage). After firing the projectile, the gun needs to be cooled down for a second. You can press X at the right time to finish the cooldown instantaneously (which gets harder each time) but if you miss the cooldown will restart.
Intrinsic perk: firing line
Catalyst: decreases cool down time to 0.67 seconds.
900 rpm
It's a craftable weapon like osteo striga.
