you can wait until December 25th and be able to just do the ONE Divine tree, correct?? Because I only want Sagittarius, I don't need anything else. If I start out with enough ornaments to decorate the Divine tree of Sagittarius, I can just wait until December 25th?? So what I am getting at is that you can decorate 15 trees(and maybe using the decorations needed for the divine trees) and after completing those trees you can unlock the divine tree before the 25th. But, if you wait and save your decorations, the 25th is when it will be opened to the public, even if you didn't decorate the other 15 trees. Am I correct?

my decorations for the divine(s)

All Divine trees require the same amount of Decorations:

6 Tinsel
4 Baubles
26 Hanging Ornaments

The Divines you can get (and what they do) - and the tree they come from are:

1. Snow;
Snow is a Divine horse built for competition. Each Snow has his name written in a color that characterizes his specialty.

Blue indicates a specialist in cross-country.
Red is for show jumping specialists.
Green designates trotters.
Purple is for horses specialized in gallop.
Orange indicates a barrel-racing expert.
The white one is a dressage expert

This horse cannot be sold. (Of the Water Divines, his skills are the worst, but he can breed with Mist to produce Ocean)

2. Frost;
Frost is a divine mare that has the ability to switch her skills around.

Her skills change every day:

One day she is great at galloping, the next day she has great stamina...

She can breed once with Ocean, giving birth to a unique foal:

Snowflake.

You can defrost Frost every day through her public page for a chance to win a Hypnos' Blanket.

On the first day of the month, when the website is updated, Frost is given to one of the players who defrosted her during the previous month.

This mare cannot be sold. (She's good for competitions, and you get two Divines for the price of one as you can use a Public Covering from an Ocean to get Snowflake)

3. Winter;
Winter is part of the Season divine horses.

Each day of Winter, win:

30 skill points you can apply to Winter as you wish
5 000 equus upon first daily login

Game:
Equus every Winter day in game
VIP:
Filter competitions one of your horses is already entered in.

This horse cannot be sold. (He gives you 35,000e a month, and since you can choose how to distribute his skill points, he can become quite a good competition horse.)

4. Sagittarius;
Sagittarius is one of the horses of the Zodiac.

If you were born under this sign, Sagittarius will give you 1 x The 5th Element every year, on your birthday, if you log in on that day.

She can breed with Scorpio to give birth to Capricorn.

By collecting all 12 horses of the Zodiac, you will get the horse, Serpentarius

This mare cannot be sold. (Unless you are a Sagittarius, she is useless to you. However - she does give you two Divines for the price of one. If you are a Capricorn - you'll benefit from her foal *who has the same perk - 1x 5th element on your birthday*)

5. Snowy Balios;
Balios is an especially generous divine horse.

On the 19th of every month, at the site's update time, it will give its owner a Nyx Pack, but only if the owner logged in the day before.

If the owner wasn't also its breeder, it gives them a Nyx Pack on the 19th of January, April, July and October only (as long as the owner logged in the day before).

Plus, its skills increase a little every day...

This horse can be sold. (Snowy is just the coat type - he's the same as any other Balios.)

As to which one is best to get - that's going to depend on what you want out of the Divine (If it was me - Sagittarius or Balios is best (Balios because of his perk - Sagittarius because I need her to get my Sign)

However, it seems that Balios might now be the hardest Divine to get (as now his tree seems to require a ton of decorations that classify as Super Rare - while the other four need a mixture of the 4 decoration rarities *still hunting for more information on if this is an intended change or a glitch)*
~*~

As for what breed(s) to use to get trees...we're still working on figuring out what works best (so far, it seems foals actually work the best - as recently when I went for trees in the Divine forest:

Friesian Unicorn - 445.08 skills - 356.16 gp
Friesian Unicorn - 384.02 skills - 353.17 gp
Time Taken = 5 Days

Donkey Foal - 90.06 skills - 306.02 gp
Donkey Foal - 90.06 skills - 306.02 gp
Time Taken = 3 days

Ocean Divine - 8569.20 skills - 700 gp
Geyser Divine - 8420.30 skills - 700.00 gp
Time Taken = 5 Days

I know that it is better to have young horses with low(er) skills to bring back the trees, but do BMIs account for it as well? I am about to get a Winged Unicorn, 5 years old, with 120 skills. Does the unicorn and wings affect the time it would take to get the tree back?
