Magic Item Creation Adding Plus to Certain Ability Checks

[Dax Doomslayer]

Hi Folks,
A really dumb question. I'm trying to have an item that would add +2 to all Wisdom Skill rolls. Is there a way to do this. I see advantage/disadvantage but not seeing anything for a specific numerical plus.

Also, while I'm asking, is there a way to code: "temporary hit points equal to your level + your Wisdom modifier"

Thanks!

For the first one SKILL: 2, wisdom. For the second see the graphic attached.

Thanks Dr. Z. I was using a semi-colon (why I don't know) for the skill and that would be the reason why. I appreciate your help!!
