Water
Procell
Shape: Female Humanoid Shadow
Skills:
Level 1: Cross Slash (physical+2)
Level 15: Mind Blast (wisdom-20%)
Level 30: (Death+3)
Level 40: Greater Cunning (wisdom+20%)
Level 50: Self Destruct
Level 70: Cunning & Haste (Wisdom and Agility + 10%)
Comments: Death skills. I heard it is another skill like the buffs that can never be learned from stones. It also does not deal any damage so it is either a kill or 0 damage. JP Wiki skill recommendation: 3, 4, 5 or 3, 4, 6 or 3, 5, 6. Personally, I'll go for 3, 4, 6.

Blizzard Phoenix (I learned from Requiem Banshee and Serenade Banshee naming change!)
Shape: Bird Shadow
Skills:
Level 1: Revive
Level 15: Aqua Shot (water+2)
Level 30: Quick Strike
Level 40: Double Impact (physical+3)
Level 50: Aqua Blast (water+3)
Level 70: Cunning & Haste (Wisdom and Agility + 10%)
Comments: Revive guardians don't normally get +4 skills and the trend continues here. It takes back the throne of Fastest Bird guardian from Stymphalian Bird but is now behind Sphinx Empress. Quick Strike chained after Last Stand is a good combo (Credits to Haruno). JP Wiki is recommending skills: 1, 3, 5 or 1, 5, 6
Thunder
Thor
Shape: ?
Skills:
Level 1: Call Lighning (thunder+3)
Level 15: Storm Impact (physical+4)
Level 30: Greater Protect (defence+20%)
Level 40: Greater Might (attack+20%)
Level 50: Last Stand
Level 70: Might & Protect (Attack and Defence +20%)
Comments: Marvel one looks nicer in my opinion. A 5* version of Golem with high overall stats, especially high wisdom. I will use Skills: 2, 4, 5.
Death
Morrigan
Shape: Female Humanoid Shadow
Skills:
Level 1: Hard Slash (physical+3)
Level 15: Dark Psalm (darkness+3)
Level 30: Greater Might (attack+20%)
Level 40: Thousand Slash (physical+4)
Level 50: Quick Strike
Level 70: Last Stand
Comments: First time I encountered a Quick Strike that can One Hit Kill Guardians! This is one of the highest overall stat guardians that now have Last Stand after rebirth. She is, in my opinion, one of the best 5* in the game. Skills: 3, 4, 5 until rebirth, replacing 3 with 6.
