Trade search missing option on flask suffix.

I've been trying to search for enduring mana flasks with reduced mana cost of skills during flask effect. I can find them scrolling, but there is not a specific option to search for "reduced mana cost of skills during flask effect" in the search option. Maybe i'm stupid, but when you type it in exactly as it says you get no search results.

Is this suffix modifier missing from the search bar or am I not understanding how to search for it?

Kind regards.

Give a negative value for 'Increased mana cost of skills during flask effect'

trade site and ingame descriptions are different sadly,
you need to know some weird tricks to find some things.

Generally what will give you a result in most cases,
is to search with ~ and then the key words that you know should 100% be in it,
like ~mana skill flask

And if the only thing stated is increased or more,
then you're probably searching for negative values.

Once you know some modifiers are treated as the negative versions of the increases, you can find nearly everything.

It worked with increased.

So I had to put in "Increased mana cost of skills during flask effect" and in the [Max value] I put "-20" which gave me flasks with the mod decreased.

Thanks for all replies :)
