| effect | id | | size | what it does |
|---|---|---|---|---|
| Arrow shot | `moves/arrow-shot` | one-shot 1.9s | 300×74 | He raises the bow, draws to his cheek, holds his breath and looses: the string snaps forward, the arrow crosses the floor and thuds home. |
| Dash strike | `moves/dash-strike` | one-shot 2.3s | 372×156 | A crouch, then he's across the floor in a blur of after-images and already cutting: a critical hit, a beat, and he hops back to where he started. |
| Earth stomp | `moves/earth-stomp` | one-shot 3.46s | 290×142 | A knee comes up, the boot slams down, the floor heaves under the target and a stone spike rams up through it. |
| Fireball throw | `moves/fireball-throw` | one-shot 6.81s | 356×244 | He gathers fire in his hand, leans back and hurls it: the ball flies, the target takes it in a blast and comes out charred. |
| Ground pound | `moves/ground-pound` | one-shot 3.82s | 304×204 | He coils, leaps out of frame height, hangs, and comes down like a rock: the floor cracks, shock waves race out and throw the target about as they pass. |
| Holy smite | `moves/holy-smite` | one-shot 2.8s | 252×182 | Both hands go up and a glint marks the target; he brings them down and a bolt of light drops like a hammer, leaving the target blanched. |
| Ice lance throw | `moves/ice-lance-throw` | one-shot 4.34s | 310×136 | Frost gathers into a spear in his hand, he throws it like a javelin, and the target ices over in a burst of snowflakes and shivers. |
| Lightning call | `moves/lightning-call` | one-shot 3s | 290×266 | An arm goes up, a sigil lights under the target, and on the downswing a thick bolt comes down on it; the target jolts through the aftershocks. |
| Meteor call | `moves/meteor-call` | one-shot 6.43s | 380×240 | A long chant: a circle draws itself round him, it flares, he points, and a burning rock comes down on the target and flattens the scene. |
| Pistol shots | `moves/pistol-shots` | one-shot 2.6s | 378×76 | Three aimed shots: the gun kicks up each time and settles, tracers cross the floor, and the target staggers under each hit. |
| Rocket launcher | `moves/rocket-launcher` | one-shot 6.56s | 480×244 | He drops to one knee, shoulders the tube and fires: the kick shoves him back along the floor, the rocket crawls out on its jet and the target goes up. |

splashes, falls, fountains, waves.

| effect | id | | size | what it does |
|---|---|---|---|---|
| Bubbles | `water/bubbles` | loop 4s | 104×112 | Bubbles stream up from a vent of pebbles, wobbling and swelling as they rise, flare as they cross shafts of light from the surface, then dome up and pop there. |

| Shatter wipe | `transitions/shatter-wipe` | one-shot 2.8s | 320×180 | A dark glass pane drops over the screen and bounces; cracks race out from an impact with a flash, then it bursts into tumbling glass shards with lit edges that fall away. |
| Slash wipe | `transitions/slash-wipe` | one-shot 1.7s | 320×180 | A white-hot blade edge slices across the screen, light ahead of it and sparks spraying back over the cover; a second cut flashes through and the cover splits apart. |
| Star iris | `transitions/star-iris` | one-shot 2.2s | 320×180 | A five-point star iris spins shut on the middle of the screen, its gold rim lit and its tips twinkling and shedding motes; it closes on a glint and spins open again from a flash. |

| effect | id | | size | what it does |
|---|---|---|---|---|
| Bat | `critters/bat` | loop 2.4s | 112×80 | A bat flaps in four snappy wing frames along a figure-eight, its body lifting on each downbeat, moonlight on its wing bones, red eyes glowing and glinting. |
| Bird | `critters/bird` | loop 2.4s | 112×80 | A songbird flies in place: bursts of wingbeats that lift its body on each downstroke, a glide on spread wings, its tail fanning, a loose feather drifting away. |
| Butterfly | `critters/butterfly` | loop 3.2s | 128×88 | An iridescent butterfly wanders a loop in bursts of quick wingbeats and open-winged glides, its veined, spotted wings shedding a twinkling trail of glowing dust. |
| Eyeball | `critters/eyeball` | loop 3.2s | 96×108 | A bloodshot eyeball floats in its fleshy lids: its glowing iris snaps from one look to the next, it blinks, and its nerve sways behind it as it bobs. |
| Fish school | `critters/fish-school` | loop 4.8s | 136×80 | A school of fish holds station in two depth rows: bodies wag into swinging tails, one darts ahead now and then, bubbles rise and caustic light ripples over them. |
| Flying skull | `critters/flying-skull` | loop 2.4s | 96×132 | A cracked bone skull bobs in the air, jaw chattering, eyes burning, a fire roaring off its crown that sheds flame puffs, embers and smoke and throws warm light. |
| Frog | `critters/frog` | loop 2.6s | 112×88 | A frog puffs its throat, blinks, crouches and leaps to snap a buzzing fly out of the air, then lands with a squash and a puff of dust, gulps and settles. |
| Ghost | `critters/ghost` | loop 2.4s | 96×100 | A sheet ghost bobs over the floor: its scalloped hem ripples and trails its drift, little arms flutter, it glances about and blinks, motes trickle off its hem. |
| Jellyfish | `critters/jellyfish` | loop 3.2s | 96×120 | A see-through jellyfish pulses: its bell squeezes to shove it up and relaxes as it sinks, frilled arms and long tentacles trailing, a glow inside, bubbles drifting by. |
| Slime | `critters/slime` | loop 1.8s | 112×88 | A glossy slime hops in place: it squashes to wind up, stretches into the jump, rounds out in the air, splats down flinging droplets that creep back, then wobbles and blinks. |
| Snake | `critters/snake` | loop 2.4s | 136×56 | A snake slithers along the floor, head raised: humps rise and roll back down its patterned body to the tail, dust puffs where it touches down, its forked tongue flicks. |
| Wisp | `critters/wisp` | loop 3.2s | 128×104 | A will-o'-the-wisp loops a figure-eight over the floor: a little soul-flame with a face, its flame tail licking up and streaming behind, shedding puffs and sparks. |
