Spell drawing
Earth Explode
This unit uses its idle pose for chanting or casting.
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.
As in the game, clouds, drops and splashes vanish together 1.05 s after the impact, when the effect is deleted. Until then the drops dim and brighten again, and each splash holds still until the next one.
The scene uses the game’s map 006 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.
The terrain change (Turns the ground into magma) lasts 20 s, longer than the scene: it stays on the map when the scene ends.

Terrain it paints
A circle of 100 px, for 20 s. The 8 × 8 px cells whose centre is inside are painted.
Inside its circle it removes hardened magma and frozen water, 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.
Against creatures
It heals fire creatures a little instead of hurting them (1/16 of its power) and does ×1.5 to water ones. Against the rest, normal damage.
Fire creatures: Salamander, Runemander, Red Shog, Flare Hound, Ruby Golem, Phoenix, Dagon, Flare Dragon, Fire Mage, Christiva
Water creatures (×1.5): Undine, Runedine, Blue Shog, Death Fish, Death Fang, Hydra, Hydro Hound, Hydro Dragon, Water Mage, Popokura
Power at cast
Before the target’s element and defenses. Each value is the game’s own formula.
