DnD 5.5 Divine Intervention & Glyph of Warding

Hi,

I would like to know if it would be possible to use Divine Intervention to upcast Glyph of Warding to store Spirit Guardians as a 5th level spell. After having triggered the glyph, does the cleric need to concentrate on Spirit Guardians? My interpretation is that the cleric does not need to concentrate on it.

Thanks for any input 

As written, Divine Intervention does not allow upcasting spells. Upcasting requires the use of a spell slot of a higher level than the spell's level; spells cast without using a spell slot are cast at the spell's minimum level unless whatever is allowing the casting explicitly says otherwise, which Divine Intervention doesn't.

A Concentration spell cast via Glyph of Warding always lasts until the end of its full duration without needing Concentration to maintain.

ok thanks. So I can use DI > GoW > SG as 3rd level spell and then use SG without Concentration

I think using Spirit Guardians with Glyph of Warding technically works as written, but be aware that some DMs might reject it as it seems to be well outside the spirit of what Glyph of Warding is for, especially if the intent is just to use it to dodge the Concentration requirement on another spell.

Note that glyphs are immobile, so no use in adventuring (unless you go the demiplane route) so fine to rig up defenses for your haven/bastion.

My high level wizard is looking at glyphs of Fly, Invisibility, Dimension Door, Non Detection for his daughters in case they need to flee the Bastion. Dim door straight up 500 feet, go invisible, fly and be unscryable to escape. A bit of gold to set up, and good reasonable paranoid wizarding.
