My party keeps dying, and every time I go to use a healing potion on one of my creatures, I am unable to go to the next phase of the battle and it keeps me stuck.
So you select a move for one sylesti and then it automatically goes to the next sylesti in order to select a move there and then you have the ability to end your turn, however with me I select the item that I want to use on my sylesti to heal him, it turns yellow which means its selected but then its completely stuck and no matter where I click I cannot proceed to the next step, making it impossible for me to use said item on my creature to heal him.
I really need to figure this out cuz Im a noob and have like 10k gold and cant keep wasting gold on reviving and healing them when they die

You have to click on the item /and/ the pet you want to use it on. It should turn green. Also, you can use an item on any pet at any time in your turn - it's not dependent on which pet's "turn" it is.

(Do keep in mind, also, that only elixirs can be used in battle; potions cannot.)

It wont highlight green it gets stuck on yellow, and the item is showing up so I know I can use it. Is it my browser?

To clarify, you are clicking on the item and then on the pet you want to use it on?

Clicking on a healing item in the Manage Party area should automatically swap it to a pet selection where you click a pet to use it on.

Yes I am

i'm sure i might be interpreting this wrong, but is it that you are unable to end turn? after selecting the elixir and pet, you must choose an attack the pet will use.

I think if it is yellow it's because you don't choice wich pet will be heal.

You click on item and when the window of the pets come, you click on the pet you want heal before close this little window. And after in th batle party it will appear green, and you choice you attack.
I think the potion is used before the attack, but not sur, sorry.

The other problem is that you have a cooldown, one tour without using potion, but for that you receive message.

Are you playing on a mobile device?

I don't know for DJSeizure, but yes for me. I play on mobile only. My advise is good for mobile but perhaps useless on computer. Sorry about it.
