The Horror Mansion Necrobloxicon — Sword Chase Staple

Necrobloxicon (also called Necrobloxian in older notes) is the chase-and-swing killer veterans use to teach the mansion’s joke: most threats still honor a desk. In The Horror Mansion by K1ir (place 522527978, released 2016-10-13), the 200+ roster mixes comedy props and unfair collision. This morph sits on the fair-ish chase side. Learn it before you attempt Limbless or ANGER44. Pair the profile with Killer Behaviors so you classify movement in the first two seconds of a wave.

Community documentation describes a pitched-black, semi-transparent figure wearing the classic Roblox hat The Necrobloxicon, Eyes of Crimsonwrath, and the Darkheart gear. Origin notes credit a catalog hat plus a free model associated with user theothervessel. The in-round audio bed is often a slowed Zero Project — Gothic stinger; laughter sells the chase. None of that is a patch note from K1ir. It is how survivors recognize the silhouette when 25 people are screaming in a tiny house.

What the round feels like

Necrobloxicon commits to the nearest survivor, swings the sword, and drains health until the lobby is empty, then idles. That is grounded pursuit, not a teleport skip across the main room. Forcefields can make it ignore you temporarily—useful if a teammate pops a defensive item, useless if you treat the bubble as a permanent camp. When the laugh track is loud and the model is still walking floors, you are in furniture territory.

The mistake is assuming every black book-headed morph is this kit. Sequel place 2739808800 (Original vs Sequel) leans unsettling; a lookalike can carry worse collision. Identify walk + swing, then climb. If the killer starts clipping desks or skipping hallways, you reclassified—leave the perch.

Opening seconds

1. Hear the laugh / gothic sting and glance at the hat-and-sword silhouette.
2. Face a known climb: computer-lab desks first, storage micro-ledges only if you already stick them. See Map Guide and Safe Zones.
3. Call “chase / Necro” so teammates do not stack three people on one pixel.
4. Do not hide in restrooms. Tight rooms help spinning comedy hitboxes; they trap you against a sword.
5. If two players die through walls immediately, you are not on this article’s kit. Swap to Limbless.

Counters that actually work

Lab desks and hallway props

Climb early, not in swing range. Grounded chase AI often stalls when you stand on desks and cabinets that lack invisible walls—the mansion’s signature exploit, detailed on Glitches. Stick the landing with forward momentum (Controls). If Necrobloxicon pathfinds onto the desktop, drop toward a second exit (lab ↔ hallway ↔ kitchen) instead of screenshotting the hat.

Doorframes and kiting

Use doorways to break swing timing, then remount vision. Do not run the same rectangle until panic eats the round. Change elevation when the chase tightens. How to Survive is the default loop; this page is the named example of “desks still work.”

Forcefields and team play

A temporary ignore is a rotate window, not a reason to AFK. With max 25 players and no VIP servers, public lobbies get messy. Use Join-on-profile from Friends & Servers if you want a coordinated desk assignment. Do not drag the sword through someone else’s only exit.

When to abandon the perch

Leave furniture if the hitbox clearly reaches the stand, if the killer noclips, or if adjacent climbers die in one swing. Then kite open hallways and accept the death if it is a different morph wearing similar merch. Rank honest failures on Hardest Killers; Necrobloxicon itself more often belongs near teachable chase threats on Beginner Threats relative to Limbless, not relative to a training dummy.

Common mistakes

• Treating Necrobloxicon like Limbless and sprinting open sightlines instead of climbing.
• Treating it like a comedy spinner and standing still for a clip.
• Climbing too late, then blaming the badge system when consecutive Badges reset.
• Installing ESP “to find the sword.” Scripts is a ban briefing.
• Farming a seasonal candy overlay that is not live as of August 2026. See Events.

Practice plan

Queue until you get a laugh-and-swing chase. Survive one wave on a lab desk, one wave on a kitchen counter, one wave kiting only. Write one sentence per death: furniture worked or not. Alternate with Umbra-style pursuit on Umbra so you feel quiet pressure versus sword pressure. New players should still read Getting Started before they call the killer “broken.”

There are no active codes to skip this homework (Codes). The classic description still says no named patch; the last universe timestamp noted on Changelog is 2026-08-02. Necrobloxicon does not need a patch blog to keep teaching the sit gag.
