Illustrative reconstruction: frames, palettes and effect timings come from the ROM. Part placement and drawing speed are choices of this viewer.

Outcome and status application are selected for the demonstration; they are not a battle roll.

The scene uses the game’s map 046 to show the terrain the spell acts on. The overlay appears on the same tick as in the game, inside its circle and with the tiles the game picks from the neighbouring cells. The spot on the map and the animation phase are choices of this view.

At the start the ground around the target is already changed (Turns quicksand into swamp). This view sets it up so you can see what the spell removes.

The terrain change (Dries swamp into sand) lasts 20 s, longer than the scene: it stays on the map when the scene ends.

Terrain: Dries swamp into sand

Terrain it paints

A circle of 80 px, for 20 s. The 8 × 8 px cells whose centre is inside are painted.

It paints nothing visible: the surface it would change is on no map.

Inside its circle it removes sand turned to swamp, even when another spell put it, while it lasts.

It appears at once and, when it ends, vanishes with no animation: the game has no entry or exit animation. The 3 frames loop the whole time. It is only the picture: the terrain status gives the effect on units. The layer’s 32 tiles with the game’s palette and frame timing; not a screenshot.
