I want to auto my Ice Golem farming but there is an issue that makes auto perform very badly. My Athel (who deals the main damage in all my combinations) only attacks with her first skill, never uses the second (Divine blades) and she uses the third skill (which gives attack boost and extra turn) wrong. 

Well, she actually uses Divine blades in the first waves before the boss. But she never ever uses it again on Ice Golem and his teo bodyguards. 

Maybe the AI makes a mistake, mistakingly thinking that there aren't multiple enemies (while there are 3)

The second and not such a big deal problem is that she uses third skill whenever possible. Considering she isn't using divine blades ever, this move is such a waste. Because she loses one turn of sweet attack and shield buffs which other champs kindly placed. 

Maybe it could be coded (I'm not an expert, just thinking) in a way that she use the third skill in two situations only: 1-she needs the attack buff (so she shouldn't have it already), 2-divine blades is on cooldown (so it would benefit her through cooldown reduction) 

Thanks for reading
