I am debating whether to use my CD Familiar Training potions on 'Checin, of the Dark' (Season 2 Ultra Rare) since it is Celestial and the only familiar to proc stealth (for stealth-required scout abilities - specifically beastlord primals) even though the stats are dated. Should I save my potions? What are the preferred or best familiar abilities, procs, or stats in the game? I hear the resurrect proc from 'Vyemm's Protector' is also very unique (but unobtainable). I also see the damage absorb buffs (e.g. Armored Dire Bear) as cool but I wonder if it's really that beneficial.
