In this question: Do the effects of spells granted by items require concentration? I asked about items that grant named spell effects, not casting spells from items or items that give a spell-like effect without a spell involved.
The linked duplicate question: Do magic item spells require concentration? only answers items that directly cast spells from them, or grant a spell-like effect without casting a spell at all. It does not answer the question I proposed which is when an item gives a named spells effect without directly casting that spell. Neither this question, nor answer are related to what I asked and are not helpful.
I would like to change the linked answer to this question: Do potions use concentration for their effects? which does address the question I asked, albeit it was only answered after I asked my question.
