[MIRROR] Adds the Ectoplasmic Outburst, a rare ghost-centric anomaly event [MDB IGNORE] (#19292)
* Adds the Ectoplasmic Outburst, a rare ghost-centric anomaly event (#73024) ## About The Pull Request This PR description might be a bit rushed because I accidentally submitted the PR and want to bang out a quick explanation of what this is before people start asking questions. Adds a new, rare, ghost-themed anomaly event -- The Ectoplasmic Outburst.  This event increases in power as more ghosts orbit it, with three important thresholds to meet. If 10% or more of all active observers are orbiting the anomaly, an effect will occur in the nearby area akin to the revenant's defile spell, damaging flooring, windows, and making a mess. If 35% or more are orbiting the anomaly, nearby objects in the effect radius have a chance to become haunted, and will fling themselves at anyone nearby for a bit. Spooky! Now, at 50% or more participation, things get serious. Ghosts orbiting the anomaly will be polled to be brought back into the world for a brief period as a vengeful spirit, anchored to a SUPER spooky ghost portal. The portal closes after two minutes (alternatively, smash it with a toolbox) and deletes all of the ghosts it spawned. Vengeful spirits are mostly just meant to smash stuff and be a nuisance while they can. It's a wonderful opportunity to let deadchat desalinate a little.  Oh, also, the anomaly is deadchat controlled. With enough ghosts, you could theoretically outrun anyone trying to neutralize it! The associated reactive armor has an effect similar to the anomaly, haunting nearby objects for a time when the wearer is struck. Not particularly outstanding, but it can introduce an element of chaos into a fight that your opponent might not expect. ## Why It's Good For The Game Anomaly events are great for ghosts. Why not make one tailored just for them! Gives admins something to spawn when a wizard has killed half of the crew but it's not quiiiite time for an ERT. It's a bit of a silly event with a novelty reward, but I think it's rare enough not to be a huge issue. ## Changelog 🆑 Rhials add: Ectoplasmic Outburst anomaly event add: Reactive Ectoplasm Armor /🆑 * Adds the Ectoplasmic Outburst, a rare ghost-centric anomaly event --------- Co-authored-by: Rhials <Datguy33456@gmail.com> Co-authored-by: lessthanthree <83487515+lessthnthree@users.noreply.github.com>
