How I would change covenant signature abilities

[Sagenod]

I think it would be better if all four of the abilities were shared across the covenants, different thematically based on which covenant you're in. Below are some ideas for these ability variants. I've a couple ideas for alterations to the ability mechanics but the changes are otherwise little more than reskins and minor rewordings of the existing abilities. Let me know your thoughts!

Kyrian - Summon Steward Variants
The items the summoned NPC sells are unique based on the covenant. Each NPC has unique collectibles that are only unlocked after fulfilling certain requirements.

Night Fae - Summon Tender - Call on a Tender to bring you a Seed of Rebirth that can be consumed to restore 20% Health and remove all Curse, Disease, Poison, and Bleed effects. The Tender additionally offers access to a selection of useful amenities for 4 minutes.

Necrolord - Summon Apothecary - Call an Apothecary to bring you a Flask of Supremacy that can be consumed to restore 20% Health and remove all Curse, Disease, Poison, and Bleed effects. The Apothecary additionally offers access to a selection of useful amenities for 4 minutes.

Venthyr - Summon Dredger - Summon a Dredger to bring you a Vessel of Repentance that can be consumed to restore 20% Health and remove all Curse, Disease, Poison, and Bleed effects. The Dredger additionally offers access to a selection of useful amenities for 4 minutes.


Night Fae - Soulshape Variants
Different starting form model and particle effects based on covenant. The confirmed additional forms are available for each covenant, modified to fit the theme. Choosing the form of a flying creature allows you to fly freely for the duration of the spell's effect in outdoor areas, or permanently in rested areas.
