Hello, thank you for your purchase <3
About the issue, most likely you changed the template conditions for the boss events, which is causing this issue, please check the template original events and watch how we set the conditions correctly, the boss shooting events can be found here:
Game scene events → Bosses mechanics → Fire wizard boss → Movements → Shoot fireball.
Boss keep firing bullets more than 3, means the object variable (NumberOfShotBullets) is not being increased, check the boss events:
Game scene events → Bosses mechanics → Fire wizard boss → Movements → Shoot fireball.
This condition and action are the one making the wizard shoots 3 bullets only, make sure you have them
As for boss not teleporting if his health got to 70 or lower means the object timer "StandStill" is stuck, double-check your events:
Game scene events → Bosses mechanics → Fire wizard boss → Movements → Shoot fireball → make sure the start timer "StandStill" action is in the event.
I recommend copy-paste the boss events to your project to avoid all kind of bugs.
