Teblats appear in a part of Rebuilding Brangmar, and they will probably show up again.
Teblats can take the form of any tiny creature. The creature itself isn’t the teblat, instead the teblat is a parasite that gives the animal protection but also causes the animal to be more aggressive and appear to have a blue aura. This aura grows stronger when they have more temporary hit points and is very dim when they have none.
Sentient creatures cannot be affected by a teblat infestation.
When a creature that is infected by a teblat is killed it turns into Blue Ash. The ash can be used as a healing powder. Rubbing Blue Ash into a wound or mixing it with water and drinking it recovers 1d4 HP.
The following is an example of a cat infected with a teblat infestation.
Tiny Beast, Unaligned
12 Natural Armor
40ft., climb 30ft.
STR 12 (+1)
DEX 15 (+2)
CON 10 (+0)
INT 3 (-4)
WIS 12 (+1)
CHA 7 (-2)
[removed stealth because of the glowing aura]
Passive Perception 13
The teblat has advantage on Wisdom (Perception) checks that rely on smell.
The teblat has advantage on Wisdom (Perception) checks that rely on sight. [Added in place of stealth.]
When the teblat deals damage to a creature it gains half the damage dealt (rounded down) as temporary hit points. Temporary hit points gained this way cannot exceed half the maximum HP of the teblat (rounded down).
Claws – Melee Weapon Attack: +1 to hit, reach 5 ft., one target. Hit: 1d6 slashing damage.
To modify a creature you usually just need to add Aura Shield, but with creatures that have the stealth skill listed reduce that skill bonus by 3 but not below zero. If this completely removes stealth then add a minor ability to the creature. After those changes, increase the Challenge Rating of the creature by .5 rounded up.
