can hexproof creatures be enchanted?

A permanent with hexproof can still be the target of spells or abilities controlled by that permanent's controller or that player's teammates. The same is true for a player with hexproof. Aura spells target a permanent or player. You can't cast an Aura spell targeting an opponent's permanent with hexproof.

So yes. For school of magic based enchantments, they stack additively with each other, but multiplicatively with the mastery perk. For example wearing 4 items (ring/robe/necklace/circlet) with 25% Destruction Magicka Reduction will allow you to cast unlimited destruction spells even without any mastery perk.

According to the Minecraft wiki: Horse armor cannot be enchanted in survival mode, but you can use an anvil in creative mode. Enchanted horse armor will not have any effects on the horse. So no, enchantments to horse armor will not have any affect on a horse.

Fishing rods can now be enchanted with Unbreaking using enchanted books. Fishing rods now have 2 new enchantments: Lure and Luck of the Sea. Fishing rods can now be enchanted in an enchantment table. Enchanted fishing rods can now be obtained as a "treasure" item from fishing, and unenchanted ones as a "junk" item.

A young or older dragon can innately cast a number of spells equal to its Charisma modifier. Each spell can be cast once per day, requiring no material components, and the spell's level can be no higher than one-third the dragon's challenge rating (rounded down).

She buys them/gets them forged. Anyone can “use” magic armor but some need a certain level of magical power to be activated and mastered properly and Erza has a natural talent for it.

Planeswalker abilities at instant speed. Yup. You can activate them once per turn, any time you could cast an instant.

Warforged are termed "living constructs" because they supposedly have properties of both constructs and living creatures. In 3e they were immune to poison but vulnerable to certain spells. In 4e they were NOT immune to poison, but they had bonuses to resist conditions like poison.

According to the wiki, books may only have one enchantment. This can be tested by giving yourself a bunch of books and enchanting them, then throwing them into lava or whatever you wish to do with them.

No, you cannot eBug superior items, but you can eBug any old Ethereal Great Hauberk. Also, the item cannot have sockets either. So if you have an Eth 1os Great Hauberk, you wouldn't be able to eBug the armor.

No, tapping an artifact doesn't do anything (anymore). Tapping an enchantment does nothing. There was a time (until 6th edition rules IIRC) when you could tap artifacts with a passive or triggered ability which then was switched off.

It's far more likely to dependably do some damage with four rolls rather than one all-or-nothing roll. This is the same effect that make fighters, for example, such reliable damage dealers in combat. An Eldritch Blast above level 5 is a more reliable attack than any other cantrip.

No, you can't see the creature's aura, but you can detect if there's magic within 30 feet of you, including magic items he might be carrying, though you can't determine the nature of the items. From the text of Detect Magic: ... You cannot pinpoint an invisible creature or object's location with Detect Magic alone.

When it is an Aura the Creature it is attached to is the "Enchanted Creature", it is never an "Enchanted Creature" if it is not attached to anything and is just an Enchantment Creature.

You can only use this effect of [its own name] once per turn. The strategy consists in the "Danger!" monsters revealing themselves in their owner's hand to activate their effects, then "hiding" in the hand again, making the opponent randomly discard a card from their opponent's hand.

"A multi-classed wizard can freely combine the powers of the wizard with any other class allowed, although the wearing of armor is restricted. Elves wearing elven chain can cast spells in armor, as magic is part of the nature of elves."
