Size Levels

A Size Level refers to the size of something. Area of Effect (AoE) unsurprisingly describes an area affected by an action.

General Information

Different things are different sizes and are affected differently because of it. Largely this relates to Area of Effect attacks and the cost of some abilities. The natural size level something works at is on the same scale as it, and it costs more energy to work outside of that comfortable range. When doing a spell you can go between the size levels by adding 2MP per level away from your normal scale. It is possible to change your natural scale at GM discretion.

When attacking this matters. Generally if you’re a size level out you divide the attack roll by 2, either because the force is spread out over too large an area or because it’s too small for them to care. However they will normally face a dodge/agility penalty against this roll, either because the attack is too large to escape or because they have a really big target to hit. Likewise, a smaller target will be harder to spot, giving a +1 to stealth checks for every size level smaller than the person trying to see them.

What are the size levels?

While this isn’t an exhaustive list, here’s a rough guideline, the usual size levels are:
Tiny: Mice, Gears in locks, individual droplets or body parts.
Small: Human size, a sinkful of water, a computer. This is the normal level for humans, you *might* be able to cover a small group… if they huddle together.
Large: Room size, or corridor size. If in the open it is a circle around 2-3 metre radius. This size level also includes things like lorries, but generally less than building size.
Massive: You see that huge space around you? This is building-scale size, most things in this category are godzilla-style monsters or giant robots. Or occasionally both.

Summary of Effect on rolls

  • Your natural size level is the category you fit in.
  • This can be changed at GM discretion.
  • You can always choose to affect a different size level, this is how AoE attacks work.
  • For each step difference of size level involved, your roll is halved. Eg. When casting on a large area it's /2, if dodging a massive attack it's /4.
  • For each step difference of size level involved, add 2MP to the cost of the spell. Eg, Unpicking a lock takes more effort than blasting the door.
  • When doing stealth checks, a +1 modifier to the check is given for each size level difference between you and the observer.
  • When rolling, differences in size levels apply for attacker and defender. This usually means you're screwed if you're fighting a mecha.
