Test each Space centre

Example: a written circular area has a 4m radius. In Tactical Mode that radius is 2 Spaces. Here only, the chosen point is at a Space centre.

1. Keep the effect’s written circular shape and 4m radius. Convert that radius to two Spaces, then draw the actual circle from the chosen point.
2. Test each Space centre. A centre inside the circle or exactly on its boundary is included.
3. A centre outside the circle is excluded even if the circle overlaps an edge or corner of that square.
4. The chosen point is at one Space centre for this example. Its thirteen included centres are a consequence of this placement, not a required template.

Result: A touched square with its centre outside is excluded. A centre on the boundary is included.

• The effect keeps its own origin, shape, extent, direction and eligible targets. Inclusion does not override barriers, cover, line of effect or target requirements.
• Do not replace a circle with a square based on shortest grid-step range. The general rule does not require the chosen point to be a Space centre.
