Try surrounding the place with 6 TB’s in a hexagon – very powerful sacred geometric arrangement. They can be small TB’s – 2.5-3oz size. In 3’s is also pretty powerful – same for EP’s.
I’m not so sure the shape of the TB is super important. Its too small on its own to have a geometric variance cause any major difference I’d think. Keep it simple and where you need more “horsepower”, 3 in a triangle surrounding a target or 6 in a hexagon out a ways (couple blocks away from the target) to surround a bigger area. These arrangements of course would be for really nasty targets as 1 or 2 TB’s for even ugly death towers usually is sufficient.
6 TB’s in a hexagon with an EP dead center (within reason) is also pretty powerful.
In general though, these are special arrangements for special cases and not something normally used in gifting but on a rare occasion you come across something that just plain needs a lot more love and then, you have to ask the operators to show you the correct configuration. They will if you pay attention and believe them.
Where shape might cause differences could be when you start adding a coil inside the TB but now thats just plain too much work except for really special targets and in something this small, 3 in a triangle arrangement around the target may well be just as good and a lot simpler/quicker to make and then the chance of them finding them all gets pretty slim.
