Critters III! Now also in 5e!

[Metastachydium]

Fur Angel

Let me tell you, this one's the creepiest of the whole lot (a monkey cat playing dress-up? [Shudders]).

Level Adjustment: --- (Improved Familiar)

What level does it become available at? I can't find where that's specified.

Manananggal

(…)

Deceptive Appearance (Su): The Manananggal appears perfectly human(oid) when not transformed, and spells that would normally reveal it's true nature must succeed in an Opposed Caster Level Check to work. Touching any item listed in it's vulnerabilities (except daggers or bright light) automatically reveals the Manananggal.

The thing doesn't have a native CL or SR and no DC is specified for the CL check. (On an unrelated note, any chance the EVIL birdy'll get stats of its own?)

Vampire Fruit

Heh. I've always liked these. Nice to see them written up.

Feats: Ability Focus (Harbinger of Doom!)

That should be marked as ^B: this thing is mindless.

Waraikumo (main form)

(…)

Skills: Bluff +20, Climb +17, Concentration +20, Diplomacy +20, Disguise +20, Hide +20, Intimidate +17, Jump +20, Knowledge (Arcana, History, Local, Religion, The Planes) +14, Listen +14, Move Silently +20, Perform +20, Search +14, Sense Motive +15, Spellcraft +14, Spot +14, Tumble +20, Use Magic Device +17

It seems to have 20 missing skill points (after accounting for synergies).

Spider

(…)

Attack: Bite +8 melee (1d3-3 plus Poison)
Full Attack: Bite +8 melee (1d3-3 plus Poison)

Damage should be 1d3-4 (from STR 3).
