Kaelo's Content

A second boss, and he is the opposite of the first one

Kaelo is a duel: you read him and you answer, and everything that happens happens between the two of you. The Void Elemental is the other half of that idea. He barely fights you — the room does.

He cannot be hurt while a rift is open. Not "resistant": five percent of your damage gets through, enough to hear that your weapon works and to understand that this is a rule rather than a bug. Attacking him is not how you win.

You win by leaving him alone and going somewhere unpleasant. He tears rifts open eight to twenty-four blocks out. Each one drags everything nearby toward it and burns whatever stands in it, and closing one means standing inside it for three seconds while it does. Shut the last one and his core opens: a guaranteed eight-second window in which he takes everything you have. Then it starts again.

The window is guaranteed on purpose. If he could open a rift the instant the last one shut, the fight would have no rhythm at all — only a boss who is permanently immune and a player who never finds out why.

He only strikes while he cannot be struck. Core bare, he is defenceless and silent. That single line is the whole fight.

And his two moves are aimed by behaviour, not by distance. A player standing at a rift is doing the work, and he leaves them entirely alone; the moves exist for the player who is not.

• Repulse — for standing on him. A ring races outward from his feet at a visible speed, and it hits you when it reaches you. Run and it passes behind you.
• The Gaze — for ignoring the rifts from a distance. A shard flies at the one person not working. It does not home, so a step to the side clears it — which means the player who dodges it is the player who was already moving toward a rift.

Different shapes in the wind-up, because two demands that look alike are not two demands. A ring on the ground around him means the ground around him is about to be dangerous; a line drawn from him to one player means that player is.

Time is the currency. Every open rift heals him, so closing them slowly undoes your own damage. And a rift left open for twenty seconds stops being a local problem — it starts draining everyone in the arena, wherever they stand. A mechanic you are allowed to ignore is not a mechanic.

No single blow takes more than a fortieth of him. He is only vulnerable for eight seconds at a time, and without a cap the heaviest blade in the mod ended the fight in four windows. The cost is worth stating plainly: past about twenty base damage, every weapon feels the same against him.

Three phases, at 70% and 35%, and what escalates is the number of rifts rather than his numbers. In the last act they open faster than they can be closed, and the answer is no longer to close them all — it is to make the window.

Calling him

The Rift Anchor — drive it into open ground and the air gives way; something arrives to hold open what you opened. Crafted from three Void Shards, a Runic Shard and a Valthera Ingot. Nothing in the recipe is gated behind the End, because he is meant to be the first boss of the void chain rather than the reward at the end of it.

It refuses to place him under a ceiling, or where his rifts would have nowhere to land — underground the surface they snap to is a cave roof a hundred blocks up, and the fight would silently have no rifts in it. One Elemental at a time within ninety-six blocks: four of him is twelve rifts, which is not a harder fight but a different and much worse one.

What he pays out is the rungs of the void ladder, not the top of it: three to six Void Crystals and six to twelve Void Shards every time — the shards are also what the next anchor costs — and a Void Core on roughly two kills in five. He feeds the crafting chain instead of replacing it.

He looks like what he does

A core wearing three crossing rings, laid out by formula rather than placed by hand. The rings throw themselves open the instant his core is bare, and the material under them goes from dead stone to lit — the same fact said twice, on the thing you are already aiming at, plus a third time in a glow that survives nightfall and thirty blocks of distance.

The rings shed pieces as he loses health. By the last act half of each one is missing, and when he dies they come apart and fly, over three seconds rather than the vanilla one.

The rifts are jagged slits of black with light bleeding out of the edges, crossed so there is no angle they disappear from, sealing from the ends inward as you close them. The pit under each one marks exactly the radius you have to stand in — a boundary that used to be invisible and found by feel.

Everything else

• Two new particles of the mod's own — void_mote and void_collapse — replacing the End's borrowed ones. The motes fall inward: everything else that hangs in the air rises, and the one thing this fight has to teach is that a rift takes.
• Three new sounds: the rift opening (played at each rift, so it tells you where as well as what), his arrival, and his death. Open rifts hum, so the one behind you is findable by ear.
• Two-handed swings had the wrong sound. Better Combat fills in a missing sound from the parent preset by attack index, not by meaning. The Oathwarden's four-attack combo sat on a three-attack parent, so its third blow — the thrust — was playing the parent's third sound, the overhead slam. The Tidespear's parent has one attack against its two. Every attack now names its own sound, and the generator refuses to build a weapon that has forgotten one.
