Metatoy System: Monster

Adventurers are bound to find creatures or monster during their adventure. These monsters are usually there to fight, eat and even tricking their victim a.k.a the adventurers. Some monster is nicer to adventurer. Below are stats for the monster in Metatoy System. I opted to use OSR term so that you can make the monster easily.

HD: HD is numbers of d6 in hit points. Often with a modifier to increase or decrease the total by the amount (e.g. HD 2+1 would be 2d6+1).
Defence (DEF): The TN when attacking this monster.
Attack (damage): Name of the attack with damage value in bracket. Some monster can attack twice or more, it will be indicated in their description.

When creature attacks or makes attribute roll (unless mentioned), it rolls 2d6 plus half of its HD, rounded up. The creature also roll make Save Roll normally (see Save Roll). Table below makes for easier reference:

1 to 2
3 to 4
5 to 6
7 to 8
9 to 10

I give an example with the famous Rust Monster and Displacer Beast below:

Rust Monster: HD 5, DEF 10, Attack: Bite (1d6), Antennae (special)

The rust monster was described as "inoffensive" but "the bane of metal with ferrous content". The creature was attracted to the smell of iron-based metals, and any such object touched by the creature instantly turned to rust, which the rust monster would then consume.

Rust monster attack twice with either bite, antennae or both. If its Antennae 'attack' connected, target's weapon or shield which made from metal will rust and corrode. It's a timid creature and only attempt to fight back when being cornered.

Displacer Beast: HD 6, DEF 9, Attack: Tentacles (1d6+1)

This beast uses a magical displacement ability, a form of illusion which causes it to appear to be a few feet away from where it actually is. This makes the creature hard to hit, while it attacks with its long tentacles. The displacer beast is the natural enemy of the blink dog.

Displacer Beast attacks twice with its tentacles. It also creates magic illusion which confuses its victim, causing attack rolls against it to have Disadvantage.

If the displacer beast is subjected to an effect that allows it to make a save roll to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.


  1. I really like how this is coming together, very interested in how "Advanced" Mutants & Machine-Guns will turn out!

    I think it is a wise decision to make it easy to line up OSR-style monster statblocks with Metatoy. Do you have a rough conversion template?

    1. I did have a table or two but mostly for attribute number and AC. Might post this in the future
