Aion KTZ bot question

[Xwave]

I hope this is a right place to post it -)

So my question is:
How do i force my bot to use healing pots AND protection scrolls?
It looks like it should just work but in reality it doesnt for some reason.

My settings are:
HP < 60% Use item Major Life Potion
HP < 25% Use item Major Anti-Shock Scroll

The reasoning is obviously that i want to use Anti-Shock in Emergency when potion healing isnt enough. However it doesnt work like this — i pull 3 mobs, my hp start going down fast, i drink a pot, my hp i still going down fast it cross 25% > 20% > 15% > 10% line ... and nothing happens :/

Note: If i disable use of life pot then Anti-Shock triggers just fine but 2 of those simple doesnt work together.
Any ideas?

Ty.
