Great idea, but what about the sword in the first image, that could be made into a heavy pierce sword too
Maybe with rocket hammer mechanics, so och isn't the only way to acquire a dashing sword

I feel the diver gear you portrayed really gove mes a steam gear element. So i was thinking if when ever the diver helm is worn, it would have periodic episodes where it releases a good amount of floating rising bubbles from around the back of it that would be similar to the bubble summer confetti. And the armor would have a wet feet aura where it leaves puddle feet marks on the ground as it walks. A player can purchase a wet aura to make the set complete hehheh.

Also that weapon really feels lile a drill lance. I feel that each lunge should spin the drill giving multiple hits in each attack and knockback at the end of the second attack at the end of the spin. It would be similar to the cutter or auto gun where it does multiple hits that flinches the enemy. On the charge attack, instead of being like a magnus where it pierces and goes though, it would act more like a sticky stick similar to the action of a graviton bomb where after it attacks an enemy, the target would get stick on the drill and take damage as long as the charge keeps going. The knight would carry anny stuck enemy with them as he/she charges. Every enemy that stuck onto the spinning drill would take damage, but the more enemies get stuck on the drill, the weaker the damage output becomes. And if the damage gets dropped to a certain point, the monsters would no longer flinched and can attack you while they are stuck on the drill. Now sense this is a heavy slow weapon, i suggest the player gets a flinch immunity on charge attack and second lunge/swipe. Also for the first version, i suggest a normal damage value and a poison or stun status chance infliction on second lunge/swipe and charge. Well awesome suggestion. Hope it's implemented.
