Ideas for Secondary Effects

Hello fellow MCreator fans.

I'm looking for some ideas (and if you know how, procedures) for some secondary attacks to add to my mod using my spellcasting system. Example: I currently have the rapier weapon class have a simple dash. Here is a list of weapons that I want to add secondary attacks to: Swords, Axes, Maces (working very different from the vanilla mace), Daggers, Bows. Crossbows, Spears (including other polearms, like a halberd) Flails, and Whips. I still haven't decided if I want different tiers of materials to cast different spells yet, so if you have an opinion on that, feel free to share!
