The middle buff beam that is outside of the Tavern needs to be placed on the two small barrels that lay next to the outside wall. The position of this beam means no enemies will aggro to the towers themselves, with the exception of wasps. 

The reflect beam extends from the small barrel out onto another barrel. 

4 LTs and 5 DSTs are used. 

The DSTs are faced: 
North
North East
North West
South East
South West
The arrows on the map also indicate DST direction. 

Depending on how healthy your minions are, you can use Orcs instead of Ogres, or add support minions like spiders and mages. 
DO NOT place support minions on the buff beams, especially mages, as their ranged attacks can aggro Ogres to them. In this case, the mage dies quickly and so does the buff beam. 

The inside core on the Tavern is actually further south, however the template used for this is the regular Tavern Defense map. Keep note of this. 

The North Eastern strength drain is only there to make the runs safer. It will diminish the damage of the Turkey's stomp attack.
