5e Monster Mash: Blood Ooze

My players encountered their second custom monster in my 5e game. Again, they didn't actually fight it. Thanks to a mind controlled cultist, they were able to get around it without a fight. So, here's the Blood Ooze:

Blood Ooze

Created by the Cult of The Leech God from demonic blood and foul magics, they are frequently left around their haunts to devour intruders (and the occasional unwary acolyte). This monster's main means of attack is to wait until someone is right beside it, then strike with it's thin, blood draining pseudopod.

Amorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing

Fetid Blood. If hit with a slashing weapon, everyone in a 5ft radius must make a DC 13 Constitution Saving Throw or be Poisoned for 1 hour.

False Appearance. While the ooze remains motionless, it is indistinguishable from an ordinary pool of blood.

Actions

Pseudopod. Melee Weapon Attack: +3 to hit, reach 5ft., one target.

Hit: 4 (1d6 + 1) piercing damage plus the target loses 5 (1d4+3) hit points due to blood loss. The ooze then recovers hit points equal to half of the hit point loss.

Not much to say about this one. Again, mostly a monster of convenience. Also, it's pretty similar, stat-wise, to a Gray Ooze. I do particularly like the image of this ooze's pseudopod being a bloodsucking proboscis instead of an acidic bludgeon
