The Build shown is for Lower stat players ---> (if u still  got  problems use spider minions  behind the walls for double dmg passive  )

 --> The Hero Stats shown are kinda my stats and just are a reference for the higher stat build cases

u can decrease slow aura range a bit with - button if needed so it wont cut the spawns for faster run time 

Build Case 1 : saver version  ( with slow aura )

-->  skip all Hermit towers  instead add a reflect wall then stack LightningTowers on Buff beam   

----> also decrease the size of the slow aura to boost runtime ( u can do that by pressing - button)

--- > reflect wall is 1 du and placed  like i show with the black arrow string icon on the map or where the Lts are 

Build Case 2 : how i do it 

--> skip Hermit towers also skip slow and elektro aura  instead add a reflect wall then stack LightningTowers on Buff beam

i use 4 heros from start  (i also dont delete my splits on reset i just build and then stack lts with adept builder still on F4)

F2  Female upper adept to upgrade ----> ( i run a mana summoner to auto upgrade and avoid cooldown and bec  im lazy )

F3 Towerboost Monk 

F4 App Builder  for passive dmg bonus on LTS (i also run upping ab on her in the 1 round and just drop mana with mana summoner to upgrade a bit  )

F5  Summoner Booster with 2x app guard 

 the LT build case is inspired by Mortey aka Fat Fk
