Not gonna say much. Had an Idea for an item that could "suck" for a long time.
Ability: Pulls nearby enemies to the players position. Jump for 2-2.5 tiles. Fall down, similarly to golden hammer drop, dealing AoE damage with 10 piercing shots coming out of the player after landing down. 350-400 damage for each shot and 500 AoE damage can work.
Basic Attack: Not sure about this part. 2 slashes that inflict bleeding can fit this weapon. Would be reasonable for balancing by adding a shot after slashes that inflicts bleeding, but then weapon will be a copy of bloodletter daggers.
The reason why tekkos look different is because I tried making actual tekko-kagi (Might be wrong cause I did only quick research)
