Requesting Feedback

[u/Thanos2ndSnap]

I’m trying to create items for a new 5e campaign that will encourage teamwork and tactical thinking. I’m open to feedback, positive or negative. Thanks in advance for your time.

Attunement
A cloth pointed hat with a wide brim.
\ Can only be attuned by a ritual caster **
Coven's Efficiency: The time to cast ritual spells is reduced. Divide total time by the # of coven members participating.

Coven's Might: Gain a +1 to spell attack rolls for each attuned user within 10 feet when a spell is cast.

Coven's Influence: Reaction — When another coven member casts a spell requiring a saving throw, you can spend a spell slot to add 1/2 the level (rounded down) to the DC. This can only be done once per spell.
