Animals changing...
The world is changing from the powers coming from the portals... cows (among other animals are not immune) some will change to mooshrooms and convert the land beneath them to mycelium as they walk around.
Gear example Bow of the Destroyer
Not to be outdone by a sword, this godly bow tends to blow things up... like everything.
Gear example Helmet of the Lich
I mean, if killing everything around you and draining its life to be your own is your thing... then well we have you covered.
Gear Example True Immortality
Yeah, Totem's are nice... but this is nicer. upon death it takes you to a safe spot away from any chance of death, and it replaces itself! also... you can't even fall to death in the void.
Gear example Sword of Power
Truly it is a remarkable item. If you feel like the power 5 bow just isn't doing it for you, you are going to want this.
Armor stand with arms
There is a mechanic in this datapack to give your armor stand arms. The glowstone is to keep the phage at bay.
Gear example Boots of Speed
While I'm sure you like your horse... when a God gives you boots to run, best to leave the horse at home. (not safe to use around lava.... or cliffs...)
Here at the end
You may find yourself here at some point. if you do come prepared!
A large portal at night
Portals come in two flavors. large portals are harder to close. they are bigger and have fire in the center.
Gear example Chestplate of Healing
It does what it says on the tin! (regen 4 while wearing) oh and this one happens to work a weak light source while wearing it.
a portal and phage
a screen shot of a normal portal a few minutes after forming. the phage below it is consuming the land.
Gear example Leggings of the Unseen
Ever wanted to be invisible... alll the time? close a portal or two and maybe the loot chest will have these leggings for you.
Withers in the pillager base
At night on rare occasion the power the pillagers harnessed that caused this mess erupts forth from one of them and turns in to a wither. On rare occasion with their new found power the pillagers win, this was not one of those times.
Horses ... and skeleton horses
At night some animals change that don't in the day. alas these horses have turned in to skeleton horses and the one in the back is a rare version. they change the ground beneath them as they move bringing the nether with them.
Gear example Shield of the Steadfast
While this shield will act as a light source even in your inventory, you might want to use it as having absorption that auto renews every 8 seconds is very nice.
pig -> hoglin -> zoglin
At night some pigs will turn in to hoglins but hoglins cant survive in the overworld, so you end up with zoglins. Also at any time some pork left on the ground can reanimate as zoglins. It just goes from bad to worse. (pick that pork up before it changes!)
Gear example Helmet of the Blacksmith
While maybe not as shiny as some of the other God level items. This one is very practical. perpetual fire proof. Good for the nether and pesky skeletons with flame bows.
