You touch a willing creature who isn't wearing armor, and a protective magical force surrounds it until the spell ends. The target's base AC becomes 13 + its Dexterity modifier. The spell ends if the target dons armor or if you dismiss the spell as an action.
* - (a piece of cured leather)
That rule only applies to armor you are not proficient with, and it only prevents the casting of spells, so if you were to cast the spell THEN equip the shield it wouldn't dismiss the spell, and any DM who says it would is a jackass for the record. "You are now holding a shield, and because of that your already casted spell that does not require concentration, something that armor doesn't affect anyway, is now dispelled."
You are just so wrong. A shield does not change your base AC, it adds +2 to it. If shields worked the way you say they do, then wearing armor would conflict with using a shield, because that changes your base AC. Shields: A Shield is made from wood or metal and is carried in one hand. Wielding a Shield increases your Armor Class by 2. You can benefit from only one Shield at a time. Mage Armor, Unarmored Defense, and normal Armor all change how you calculate your AC, but shields specifically increase your existing AC, just like the Shield Spell, which adds +5 to your AC. Also, even though you can't CAST Mage Armor while wearing a shield if you are not proficient with it, you can still cast the spell THEN equip the shield, and you can do the same with concentration spells too, because it only interferes with the casting of spells, not their duration or your concentration. You could easily cast Mage Armor and Shield of Faith and then equip a shield you are not proficient with with no consequences.
You could not in fact use that to lower their armor class, because the creature can choose which calculation they take. Nothing can stop you from casting Mage Armor on an enemy, but they choose their armor class calculation.
The enemy is unlikely to willingly let you cast on them. It requires a willing target. It could happen, but isn't likely.
In re-reading it, it's clear that the 'you 'in 'you choose' is with respect to the one whose AC calculation is being adjusted, so there is no percentage in tricking someone into willingly having mage armor cast on them to reduce their AC. TBH I wish this spell gave you a +1 regardless of your AC in cases where AC was already 13 or higher. It would increase the utility of the spell without breaking anything or stepping on the tank classes toes.
If I as a Sorcerer cast Mage Armor at a myself or another creature as a Metamagic Extended spell for a duration of 16 hours before a long rest. Does the spell expire during the rest or does it last for another 8 hours after the rest?
Though you need proficiency with shields first, of course. That +2 is nice, until it gives all attackers advantage against you, lol.
No it doesn't.
From Sage Advice:
"Can you use a shield with mage armor? Mage armor works with a shield. Shields are grouped with armor in the equipment rules in the Player’s Handbook, but various game features distinguish between the armor you wear and a shield you wield. Take a look at the monk’s Unarmored Defense feature and compare it to the barbarian’s version to see what I mean. In the monk’s version, you must both forgo wearing armor and forgo wielding a shield if you want to benefit from the feature, whereas a barbarian must only forgo wearing armor."
I'd suggest working with your DM so you just assume it's always active. Why wouldn't you? Since it doesn't use a slot. That way, just go into your armor class and modify the base to +3.
exactly why is it either or his armor is natural requires no skill cause no penalty to movement stealth or spell casting its not put on the barbarian and monk gives you bace ac tortle 10 natural armor 7 negate the dex add the con or wisdom
monk doesn’t lose his wisdom adjustment just because his dex is shit
How to Arm a Rebellion:
Mage Armor has a range of touch and doesn't require concentration. You can cast it on any unarmored person. If you have it with Spell Mastery, you can cast it on every unarmored person. With a duration of 8 hours and not requiring concentration, you can outfit the entirety of your ragtag army with decent armor.
This is not true in the player's handbook it is only specified that you can't stack unarmoured defense meaning if u are a barberian/monk u can chose between 10+con+Dex or 10+wis+Dex but mage armor does not count as unarmoured defense meaning that u can use this with unarmoured defense therefore ur AC with a monk with mage armor would be 13+wis+Dex

Player's handbook says if you've got multiple sources for calculating your AC you only get to choose ONE to use, with one being the operative word. The two ways you are calculating are as follows:
Unarmored Defense, straight outta the monk class description, and the description for the spell mage armor. Sorry but your DM is right (at least according to RAW) to limit you to one rather than the other! Plus 19 AC is crazy.. plus you have patient defense, deflect missiles, step of the wind, slow fall, evasion, diamond soul... TONS of survivability-related features. Add in optional quickened healing and subclass stuff like wholeness of body... phew bro, that's a dodge tank.
You wield a shield not wear, shield does not dismiss spell.
I'm curious for other's comment on this topic.
The way I interpret this spell, when used in conjunction with the Shield spell, is that they both STACK. Non magical armor and shields already normally stack in DND. You get AC buffed from both Armor and Shield combined. They are different categories of equipment, you can use one or the other or both. I see no difference why the magial armor and shield spells wouldn't work the same. If the game creators wanted to prevent that interpretation, they should have explicitly said so in the spell discriptions. The current descriptions of these spells says nothing to suggest that you can't use them at the same time. It only explicity says that this spell doesn't stack with AC you get from other Armor.
EXAMPLE:
A L1 Wizard with AC 12 casts Mage Armor during adventure. This consumes a L1 spell slot. Spell lasts 8 hours. It Changes BASE AC to 13 + Dex Mod. If original AC was 12 and Dex is +2, Mage Armor changes wizard's BASE AC from 12 to 15 for 8 hours.
Next, wizard enters combat within the 8 hour Mage Armor duration, on a monster's turn, it throws a 19 attack roll targeting wizard. Wizard elects to take Shield reaction in response to the tiggering attack adding +5 to AC. This consumes another L1 spell slot. The wizard's BASE AC was 15 from Mage Armor, and shield reaction now adds a +5 bonus, wizard's AC is now 20 against the triggering attack, Attack now fails. Wizard continues to have AC 20 until the start of its next turn providing protection against additional attackers.
As long as you don't mind chewing up spell slots, AC20 is pretty solid defense for a typically fragile L1 wizard.
Maybe if it was self only, but this can target noncasters.
