So I decided to watch the new weapons vid in slow-motion and caught a few abilities.

Sword Draw: Flash Strike - Dash forward and create an AoE behind you.
Sword Draw: Mirrored River - Flash Strike but worse hitbox + longer cooldown for some reason.
At least it looks cooler. Does an arc slash above you.
Knocking Blitz - Dashgrab that multi-hits then sends them forward or backward/nowhere if it bugs
Striking Gale - Slash that sends forward a tornado which explodes on impact.
Flying Slash - Sends a big diagonal slash forwards.
Twin Crescents - Flying Slash but it sends 2 smaller/less damaging projectiles instead of 1.
Piercing Gale - Spin in a circle and send a projectile made from a jet of air forwards, can deal knockback.
Rising Tide - WoM Rising Tide except angleable and can apply Soaked.
Appparently I’m completely missing a projectile attack that’s short ranged and travels in a line. Also leaves behind something somewhat like a railgun from halo. I can’t find the name for som reason
Sword Draw:MIrrored River- you dash forward and swing the swords above your head in an arc, you don’t travel in an arc
Knocking Blitz- basically what you said, last hit applies knockback, onslaught has a similar thing
Striking Gale- Summons a FUCKING TORNADO above the slash, that is all
Twin Crecents-basically that, Mim was too close to the ground to see what the projectiles looked like, but they seem to be just small slashes.
Sword Draw: Flash Strike- We’ve seen this one before, basically you dash forward and leave a slash in the air
Piercing Gale- Staff move, does a 360 and releases effectively a beam attack, similar to Exiled’s armor piercer
Flying Slash- Sends out 1-3? slash-like projectiles
Rising Tide- Basically Rising Tide from WoM but better, can now clash with other weapons and also applies soaked
That is all it seems
