So I had a pretty ridiculous idea, which I can totally see as being too difficult to pull off or unwanted for a number of reasons, but here goes.
What if there were Fiona rewards for bonding with every familiar in a holiday series? I wouldn't expect it to include retired familiars, but for instance, achieving Awakened with every one of the
goblin familiars gets you a brand new (new lineart and pose--not a recolour) non-elemental goblin (or a rainbow goblin? :D). Or bonding with all of the
gem guardians gets you a little guardian who hoards all the gems!
Of course, even with the familiars not being retired, I can see how there being so many and much harder to obtain, this would be an obnoxious idea for new players. Maybe the familiars can be replaced by Joxar's recolours, instead, since those are consistently obtainable? Imagine bonding with all
nymph familiars (Joxar's sprite recolours) and receiving a brand new sprite/nymph (though I may be biased because I love the sprites so much)!
I specify a brand new familiar rather than a recolour simply because reaching Awakened status with 11 familiars that are released over a staggered period of time isn't a simple feat--plus, the holiday familiars in a set aren't recolours of
each other. So it would be a really big and cool reward for people, plus the familiars already follow a theme so it mostly means making a neutral aligned familiar of the same set.
I'm also waiting to see how we'll be getting a Capricorn familiar to go with our zodiac set (I was expecting it was going to be an item from last year's NotN), but this would be a perfect way of doing so if they don't already have one planned! That, or bonding with all 12 zodiac familiars gives you an
Ophiuchus familiar. :D
