Ice Goddess

Rune 1 of 2

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.

In the game, each effect family decides when it is removed. This spell’s family is not decoded yet: the scene removes it 2 s after the impact.

The scene uses the game’s map 016 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 (Freezes water) lasts 20 s, longer than the scene: it stays on the map when the scene ends.

Some part or sound assignments still need verification.

Inside its circle it removes melted ice, 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 water creatures a little instead of hurting them (1/16 of its power) and does ×1.5 to fire ones. Against the rest, normal damage.

Water creatures: Undine, Runedine, Blue Shog, Death Fish, Death Fang, Hydra, Hydro Hound, Hydro Dragon, Water Mage, Popokura

Fire creatures (×1.5): Salamander, Runemander, Red Shog, Flare Hound, Ruby Golem, Phoenix, Dagon, Flare Dragon, Fire Mage, Christiva

Power at cast

Before the target’s element and defenses. Each value is the game’s own formula.
