Hello I am Merastar and I am making this guide for those who wants to try something new to this old game! Tavern Siege Nightmare Pure strategy without auras and harpoons. I have tested this build 3 times so its a good set in stone wonder.

Ok you will need around 3k stat builders (for optimal comfort) and the following builders:
Apprentice
Huntress
EV
Summoner

ok for the huntress you will be needing gas traps and inferno placed at the Tavern exits and on each path of the outer crystal. the outer crystal is the only spot where gas traps are placed to slow those rush phases of orcs.

For the rest of the defense units you will build 7 buff beams (4 DU buffs in tavern and 2 5 DU buffs for the bridges and 1 6 DU buff behind the crystal) as shown in the images I will show for the end build.

You will be building a lot of apprentice towers which are the meat of your defense so you really do want to max out this builder as much as you can. you will have 1 Deadly striker 1 Lightning tower and 1 Fireball tower for the right exit of your tavern all placed on the back buff beam (as shown in image), you will have 1 Lightning tower for the upper exit to the right in the tavern, and you will have 2 lightning towers, 2 fireball towers, and 1 Deadly striker all lined on the 6 DU buff beam behind the outer crystal.

For the summoner this is where you want the 3k stats especially minion health because they will be acting as your walls in order to make this a comfortable run. you will need 2 mage minions and 4 archers for the the right exit of tavern, 1 mage and 3 archers on the left exit, and the outside crystal will have the most minions positioned as so on the buff beams : 2 archers,2 mages, 3 archers. you will have enough DU left to make 1 archer so put him to the far left of your 6 DU buff beam to protect against those pesky spiders that try to sneak on your Lightning towers.

Final finish for Right exit of Tavern:

Final finish of Left exit of Tavern:
Final finish of the Outer crystal set:

Now if you are hosting with 3 other players you can have 1 person on each side the tavern defenses and 2 for outer crystal set. and as you are building the mage towers if you need a reference of angles just zoom in on my photos I posted. if people are upgrading at a steady rate you should not have a need to repair defenses ever.

There you have it. My Tavern defense no repair pure strategy build. If I can make this guide any easier just give me the feedback as this is my very first guide I have ever made. Thank you and I hope you enjoy the build :).
