Apex Arcana: Tides — T.O Magic 'n Extras Addon

Apex Arcana: Tides adds one ultimate to the aqua school that T.O Magic 'n Extras brings to Iron's Spells 'n Spellbooks — built as part of the Apex Arcana set, at the same scale and under the same rules.

Parting of the Sea

A path seventy-two blocks long opens down your aim, and on either side of it the sea comes up out of the ground: two walls of water sixty-four blocks high, sheer on the path's side and falling away outside like the edge of a sea heaped up, rising one stretch after another away from you.

For four and a half seconds the sea stands parted. Light coming through the walls ripples across the floor of the path and over everything standing in it, water runs down their faces, spray blows off their crests. Then both walls surge in, meet over the middle of the path, and come down on it.

• Thrown in. Whatever stood where a wall rose is thrown into the path.
• No way out through the sea. Anything hostile that tries to leave through a wall is thrown back out of it, choking, and loses its air while it is in the water.
• The sea lets its own through. You and your allies swim through the walls freely, with water breathing while you are inside them.
• The sea closes. Everything hostile in the path takes 3.4× spell power, is driven into the ground and slowed, and the flood runs out across the floor.

T.O's aqua school throws water, calls a wave, a vortex, a rainstorm and creatures from the sea. Nothing in it opens the sea and holds it open. This does — and the wave you would normally have to run from is the one you trap the enemy under.

How it is drawn

The walls are not blocks and not a model. They are ray-marched: real refraction of whatever lies behind them, light that gets darker the deeper it goes into the water, and true depth, so anything standing in the path is in front of them and anything behind them is hidden. The light on the floor of the path is laid onto the actual terrain and the creatures standing on it.

With a shader pack (Oculus) the walls are drawn as ordinary geometry instead and the light on the path's floor is left out; everything else, and all of the gameplay, is the same.

Part of the Apex Arcana set

• Counts as an Apex Arcana ultimate for the one-ultimate-per-book rule — and goes with its switches: general.onePerBook in Apex Arcana's config, or /gamerule grandsigilOnePerBook false.
• Uses Apex Arcana's damageMultiplier and maxTargets config.
• Two advancements, a damage type with its own death message, English and Korean.
