There's one thing I'm imagining

That would probably be too OP on a melee weapon user, but I'm still hoping that one day a legendary dagger with this effect will be released.

It sounds pretty silly, in more ways than one.

Think about a blade tome bow.

I don’t think it would be unreasonable since most units have higher Defence on average than Resistance, so it would technically be weaker than it’s existing counterpart, not to mention it’s competition with Brave Bows. However, it would probably be a legendary weapon, just like Nidhogg.

Imagine INTSYS putting a effect like that on a staff for shits and giggles.
