Its costs are concentration + (all the other spells you could have cast with that slot) + (all the other spells you could have learned instead of it) + (all the other things you could have done had you been anything other than a Bard/Cleric/Druid/Sorcerer/Wizard). But it'...
in part, says, "While concentrating, you can move the image within the range," and the 6th-level Sor/Wiz spell permanent image [illus] (PH 259), in part, says, "By concentrating, you can move the image within the limits of the range." Fortunately...
You are now also concentrating on the spell. If a cantrip is readied, a bonus action spell can be cast as long as it does not require concentration (as you are already concentrating on the readied spell). If a spell cast using a slot (i.e. a non-cantrip) is...
This'll be mostly concentration spells, or magical items and class effects that have a phrasing along the lines 'as if you were concentrating on a spell'. As a bonus action, you cast command, without expending a spell slot, and you take on an appearance of unearthly beauty for 1...

While I might not agree with it, you told us to assume you cast spells duplicated by wish, so I will. Empowered Evocation says you can add your Intelligence modifier to one damage roll of any wizard evocation spell you cast. Chaos Bolt is not a wizard evocation spell...
Using the grappling rules theory, I would say that every time the Animated Armor had an action it would have to either decide to continue grappling the PC, or make an attack. If it decided to continue to grapple that PC, it couldn't make any other attacks. If it wanted to attack anot...
I suspect that the rules about spells and targeting forgot to take the "cast-and-hold" of readied spells into account, and thus didn't clarify how it works. Sage Advice has said that you choose the target of a Readied Attack when you take the attack, so I don't s...
