In need of a simple clicker bot

Hello. I am looking for a simple clicker bot for a game called Orna. I dont have any interest in GPS spoofing. I merely need a script to do something like this:

search for and click on 1 of the monsters that pop up. (on this game you never really run out of monsters to kill they just keep coming)

click a spell

click spell again if monster still living. 

when its dead click ok/continue

when my health / mana is low click auto heal

thats all I need it to do. 

The main trick is that there are a bunch of monsters. On the game's website there is a picture of every single monster. There are items you can use to only allow monsters at your tier and 1 tier lower to appear(ring of sacrifice, or affinity candles). There are 10 tiers in total. I am tier 7. 

So really I would need a script that would attack tier 6 & 7 monsters. 

Then I would need one for 7 & 8
 
then 9 & 10

So basically the same script could be used every time, I would just need to change the monsters it searches for. 

And obviously I do not expect you to do any of this for free lol. Please let me know what you think is fair, I am a reasonable person. Thank you for your time reading this XD
