I created two new magical items. Stil trying to finetune the prices. Any feedback would be welcome. I have posted the description of the items in the post and you can vind the files atthe bottom of the post.

Scroll of translation

Category: Scroll

Caster Level: 0
Market Price: 500gp
Weight: 0.1lbs
Cost to create: 400gp

Reference:

The scroll of translation is an uncommon magic item. it is created by using the tongues spell on an empty scroll  fur 1 week.

To the casual observer the scroll looks like a mainly  blank scroll. The scroll is divided in two parts by a thin giled line. at the top of the scroll the words "ad unum omnes linguis" are written in curly letters. Thos made by the original inventors also carry their names on either side of this phrase: Kragmire and Gerwoltz.

The scroll has the following properties. The scroll can translate any language written on it and creates a written output into the target language. In order for this the writter must know both the name of the unknown language and the target language and write them on top of the scroll divided by the gilded line.  The scroll works for thirty minutes a day and will regain it's charges after a long rest. If you fail to correctly identify the languge used to write on the scroll, the scroll wil go in overdrive and lose all it's remaining charges for that day.

Staff of the windwaker

The tops are inscribed with air runes. The weapon deals 1d8 bludgeoning damage. being attuned to the staf gives  you a +2 bonus on initiative rolls. Additionally the staff has 1d4 charges. A charge can be used to extend the reach of an attack by 5 feet by creating a gust of cutting wind. Players are allowed to use several charges at once to extend their attacks by a maximum of 20 feet. An attack dealt by using this ability will cause 1d8+dex modifier slashing damage. After a long rest the staff regains 1d4 charges.
