Hint 1: typically 2 DST's go on the pole thats there and the other 2 go next to them.
Hint 2: these go underneath the wood may have to kinda of "hide" them as sometimes when ogres come out of the door next to each they can throw a snot ball and hurt them.
Hint 3: This LT goes on the rock hanging of ledge under the wood.
Hint 4: Just for DU usage but ogres will throw snot at them sometimes instead of your other towers so they nice "distraction".
typically you can stay on your app to get max damage and if you have power gemstone that buffs 4 towers helps tons, but once last ogre in wave dies you should over to the Hint 2 LT's and let the gemstones work on them to help finish wave. works well also if u use monk with gem and tower buff. yes, you lose 33% damage but tower boost with gem kinda makes up for it. your choice either works. FYI standing on top of your DST warriors wont attack you.
