The thing to keep in mind is that the purge swells based on the number of thralls you have defending your money bin.
Therefore the fewer the thralls the better. Not only will there be a smaller number of enemies, but it will also be a quicker process.
This one has never needed more than three Merc banners and Death Metal (Death Metal is the name of this oneâs Golem. Doesnât matter what it is made of, it is always Death Metal)
Then again, this one does not place their money bin in the open. There are a few lovely plateaus that have only one direction to approach from but many valid spots for bases to spawn at, most of which give a long run for you to harass them.
In this, we embrace the strategy of the bear.
The Salmon must swim up steam, we need only wait at the top of the most burdensome ascent to receive them.
Make the ascent more burdensome. Lay some spike walls out. Not blocking, but funnelling, enemy AI will touch it from time to time. This one likes to think it is because the Stygians are horrible masters and their soldier just want to die to be free of this horror.
Anyway, the banners have space which is fine. They are just there to slow and soften the enemy. Enemies already softened by running thru a trail littered with spikes and raining gas arrows.
Oh, always use poison gas. It is very rude not to poison Stygian guests. They are so used to it in their serpent haunted home that to not offer them poison is the height of bad manners and indicates one does not respect the Malevolence and Resilience of their guest, perhaps even implying Set doesnât favour them
Anyway, the Mercs sit outside the very basic rat maze.
Did you know Stygians love rat mazes? Serpents often eat small rodents, so by running thru the maze, they can emulate the hunting patterns of their patron god. Be certain to leave prizes in the maze, especially Stygiansâ favourite food, poison! Party favours like that can be in pressure plates, thrown as bottles of joy, or reined upon them with all the attention they deserve.
In the mid point of the maze-
Oh, make certain the maze isnât actually a maze, instead being three or so paths that all lead to the destination. We donât want anyone to feel left out, everyoneâs a winner today! 
In the mid point of the maze is disco floor and Death Metal. The Dance Dance Revolution Party Machine. It provides itâs own ambiance for the guests, and when they finish dancing, it has a spicy parting gift. Afterwards, the guests may be all tuckered out.
Let them sleep
This is important. To make the Stygians feel more at home, they need to be stepping over the fallen bodies of their camarades. Itâs how they do it in Khem, and we must be good hosts. Many will stop and admire the progress their predecessors make. They may even just stop and stare at people whom they had hoped to be the one to take out.
You can use Sorcery if you wantâŠ
But itâs not that useful.
See, if you talk to any Yoggites, you know, Stygians donât actually taste good. So undead donât really bite at them.
Also, they arenât afraid of the dark, so the turning off the lights doesnât matter.
About the only thing that they do notice is the Electric Bugaloo, and even then the lightning is just as likely to strike your money bin and atomize the party favors as it is to make it to guests.
Also, as a good host, you will be splitting your attention between raining party favors on the guests already in the club, and showering those still approaching so they find their way. Just kept the path full of green mist as much as possible so they know where to go.
If any of them survive to the actual main promenade, congratulations, you get to dance with them directly.
Unfortunately, a level 10 party, like many other such things, often overstays itâs welcome. What would be fun for about 5-10 minutes drags into the 20+, and everyone gets foul tempered, the party favours run out, the bouncers leave. But by then, the guests should also be just about spent.
Yes, this sort of celebration is expensive.
It has to be, the entire purpose is to flaunt wealth.
So donât be stingy.
Hire the best bouncers, stock up on more party favors than you need.
No one has fun at a miserâs party, least of all the miser.
This one hasnât successfully hosted a gospel party yet.
Everytime this one invites an Avatar to join, the game passes the cluck out. No Yog cleaning service to go chew up stragglers, no Jhebbal Taxis, no stomping parties with Mitra, no pole dancing Derketo, Canât even give them a taste of home with a still born snake god.
In fact, the last time this one attempted, it fully baked their PStato. The poor thing had the most horrific case of device asthma and got heat stroke soo bad they had to have a database rebuild.
Ultimately, itâs an unpolished subsystem, and due to the specifics of it, is not where Thralls could ever shine.
But then again, anyone who leaves a thrall to guard their base in PvP knows the slaves secretly hate their masters and will let anyone in.
