It's not out in the UK until the 15th so hopefully late next week.
What monsters would you like? I can scribble off the basics from a few of them from it.
Here's the Ghoul (Med Undead CE):
AC 12 HP 22 (5d8) Spd 30'
Abilities 13/15/10/7/10/6
Immune Poison & Charm
Darkvision, Passive Perc 10
CR 1 (200xp)
Melee Bite +2; 9 (2d8+3) piercing
OR Claws +4; 7 (2d4+2) slashing & the target (not elf or undead) must make a DC 10 con save or be paralyzed for 1 min. (Can repeat the save each turn to end it early)
And Skeleton (med undead LE)
AC 13 HP 13 (2d8+4) Spd 30'
Abilities 10/14/15/6/8/5
Vulnerable Bludgeoning
Immune Poison
Darkvision, PPerc 9

Immune Poison
Darkvision, Pperc 8

roll a con save vs DC of 5 + damage taken. On a success, zombie has 1 hp.)
Slam +3; 4 (1d6+1) bludgeoning
There. Now you can fight some undead.
