Wands and Staves - Potential Mechanics for Arcane Foci

[Zalakoth]

Will brainstorm, and update if I come up with something.

Just a little bit of an Idea I came up with:


Staves:
Add Spellcasting modifier to the damage of each damaging spell you cast.**
Increase your spell save DC by 1
Doubles as a melee weapon

Wands:
May cast a spell in place of an opportunity attack
All Cantrips that have a casting time of 1 action, have a new casting time of 1 bonus action.
Cantrips may be cast in succession with any other spell. when being used in this way with another damaging spell, the user does not add their proficiency bonus to the Cantrip's attack roll.*
Very small and Concealable



*For Example:*

Casting Misty Step, and then Firebolt = Proficiency bonus for Firebolt
Casting Fireball (at 3rd level) and then Chill Touch = No Proficiency bonus for Chill Touch

Casting multiple spells in combat takes a lot of concentration and I believe that this is a way to mirror that.

**This effect does stack with the bonus granted by School of Evocation Wizard Class**




The removal of the Proficiency for fast casting Wands, and the Large, Obviousness of staves I think are a good way to balance the bonuses out. Thoughts?




Like I said, I am very confident that this will work for my group; Every group, however, is different.



On top of that, I am a Huge fan of Narrative gameplay, so for my group - Verbal components are also negated by the use of a Focus.
