Enspelled Staff casting stat

Something that came up last night.  One of the players (me) pulled out a  Enspelled Staff of healing word to save healer that had dropped in your part.  When it came time to heal we realized that the  Enspelled Staff does not tell you modifier from the stat.  For the moment we just did the 2d4 to keep the game going and figured we would look it up.  when I did they give you the DC or attack (for level 1 13dc or +5 attack) but not the stat.  It looks like it should be set at a +3 making the healing 2d4+3.  what do you all think?

I dont think it gets a bonus. I think its just 2d4 healing.

Crafting magic items rules dont say anything about the ability modifier of the person crafting an item goes into the item. You can build items in the dmg, it takes time and money based on rarity, and your spellcastinf modifier doesnt enter jnto the equations anywhere. The item does whatever the description says it does.

This really sucks for my artificer because i can make common and uncommon items, which have lousy tohit and save dc values, even though my int is 20 and intmod is +5.

I think technically the answer is that you fall back to the general rules on casting spells from items, which say that you use your own spellcasting ability if the item doesn't say otherwise (and if you don't have a spellcasting ability, the modifier is treated as +0). This rule is somewhat obscure, found only in the Treasure chapter of the Dungeon Master's Guide.

That said, that's not a very satisfying answer, and in practice one might want to house-rule something more sensible. One thing I've seen people suggest is to work backwards from the save DC and attack bonus that are specified from the item. These seem to be calculated based on taking the spell level, finding the class level a single-class full caster would have to be to cast spells of that level, and combining the typical spellcasting ability modifier one would have at that level with the proficiency bonus one would have at that level. With that assumption, one could then subtract the proficiency bonus from the provided attack bonus and get an ability modifier. This would end up with the following:
