No. Medium armor proficiency is not the same thing as the Moderately Armored feat.
If you take the Moderately Armored feat, you gain medium armor proficiency, shield proficiency, and +1 to Strength or Dexterity.
If you merely happen to have medium armor proficiency from your character class, all that happens is you have medium armor proficiency. That's not ...
When you start with an armor proficiency you do not automatically have the Feat. Feats are optional if the DM allows it. Human Variants get a Feat at level 1 and all classes can take a feat instead of an Ability Score Improvement if Feats are allowed.
The basic rule for armor states:
Anyone can put on a suit of armor or strap a shield to an arm. Only those proficient in the armor's use know how to wear it effectively, however. [...] If you wear armor that you lack proficiency with, you have disadvantage on any ability check, saving throw, or attack roll that involves Strength or Dexterity, and you can'...
Both the shield and creature take 8 damage.
You and the shield each take any remaining damage, possibly breaking or destroying the shield.
could be interpreted in a couple ways, but one is far more likely than the other; the words "each take" are used instead of "split" or similar language. Both the shield and creature take any amount of ...
Both capacities stack
The Crippling Critical ability states that:
When you confirm a critical hit using a light or one-handed piercing weapong, you can apply one of the following penalties [...list of possible penalties...]
These penalties last for 1 minute, except for the ability damage, which must be healed normally, and bleed damage, which ...
It is DM Discretion
But personally I lean towards no, because being a human is not listed as being a racial feature of being human.
You retain the benefit of any features from your class, race, or other source and can use them, provided that your new form is physically capable of doing so. (the spell shapechange)
so logically when you shapechange you ...
Gives one additional casting of the spell per long rest.
The feat provides for one casting per long rest at the spell's lowest level. No mention of consuming spell slots, so this casting doesn't.
You learn that spell and can cast it at its lowest level. Once you cast it, you must finish a long rest before you can cast it again using this feat.
Unless the source of your advantage is dependent on something that doesn't apply to attacks of opportunity (like taking the "Attack Action"), you can absolutely get advantage on an attack of opportunity.
In the case of your specific example, the Mounted Combatant Feat states that (PHB, p. 168):
You have advantage on melee attack rolls against any ...
You have to take the Moderately Armored feat to get Shield proficiency
It doesn’t matter that you have Medium Armor proficiency from your race; proficiency with Shields is a different proficiency and the Moderately Armored feat is the only way to get it without multiclassing.
This is not an oversight. The designers wrote it that way in plain English so ...
For the purposes of the Two-Weapon Defense feat in particular,
Two-Weapon Defense [General]
Benefit: When wielding a double weapon [...] you gain a +1 shield bonus to your AC.
It doesn’t get any more explicit than that.
Ambidexterity was a feat in 3e, which was removed from the game in 3.5e. It is no longer necessary at all; its benefits ...
Your problem is the order, not the feats
As already pointed out by another answer, feats have no such limitations, the only limits you are faced with are the limits on actions, bonus actions and object interactions.
I assume you're talking about a hand-crossbow and not a normal crossbow, else it becomes even less possible, but:
Action: attack knight #2 ...
Feats aside, The second crossbow attack is not possible due to the ammunition property. You couldn't have reloaded while also using your shortsword because there was no free hand.
The mobile feat has no mention of actions required to work. It is a passive feature that can be used any time you attempt a melee(homebrew: any) attack.
No, the Least True Dragonmark, Lesser True Dragonmark, and Greater True Dragonmark feats, as well as the Siberys mark ability of the heir of Siberys, do not affect, and are not affected by, sorcerer spellcasting. Those spell-like abilities are completely independent. This was equally-true of their original 3.5e counterparts.
However, in Dragon magazine vol. ...
Servo Crafting also upgrades your find familiar
While Quicksmithing lets you take find familiar as one of the spell, it does not do anything to alter that spell. Servocrafting does three things to it:
The familiar is a Servo instead of a normal familiar form (Servos can be found on page 32 of Plane Shift: Kaladesh)
The telepathy is extended from within 100 ...
The Servo Crafting feat enhances find familiar, the Quicksmithing feat does not
It is true that you could pick find familiar as one of your ritual spells via Quicksmithing:
When you choose this feat, you master two magical
effects, each of which recreates the effect of a 1st-level
spell that has the ritual tag. These spells can come from
any class ...
Prepare incarnation of evil
Spells That Have Come Before, in part, says "For the purpose of adjudicating effects that apply to polymorph spells, any spell whose effect is based on either alter self or polymorph should be considered to have the polymorph subschool" (Player's Handbook II (May 2006) 96 and here).
This means that a cleric can prepare the 5th-...
You can't use the bonus action attack after an opportunity attack.
The extra butt-strike attack that you can make with the Polearm Mastery feat has several requirements that you can't meet in this situation. Lets look at the relevant part of the Feat's rules (from the PHB, page 168):
When you take the Attack action and attack with only a glaive, halberd, ...
Polearm Master reads as follows (emphasis mine):
"When you take the Attack action and attack ..."
Since opportunity attacks are not "taking the attack action", Polearm Master does not apply. You make only the regular attack as your opportunity attack.
Regardless of what either Crawford or Mearls has said, I note that this question is often misrepresented. The text of Crossbow Expert is not:
When you use the Attack action and attack with a one-handed weapon, you can use a bonus action to attack with a hand crossbow you are holding.
When you use the Attack action and attack with a one-handed ...
The Charger feat description reads, in part:
When you use your action to Dash, you can use a bonus action to make
one melee weapon attack or to shove a creature.
—Player's Handbook ch. 6
Booming blade is a cantrip (a spell). Its spell description states, in part:
Casting time: 1 action
As part of the action used to cast this spell, you must ...
The feat Convincing Persona is useful not only to those who possess the extraordinary ability dual identity (a level 1 vigilante class feature) but also to those who've undergone the ritual of creating a masked persona, an "option available to all classes."
However, the Convincing Persona feat is pretty much useless if a creature doesn't possess the ...
The second bullet of the ritual caster feat outlines the costs of the process, and those rules are unchanged for Adventurers' League. The AL Player's Guide (on page 3 in v9.1, current at the time of this post) talks about how many hours you can spend in each downtime day copying spells.
The first part of the second bullet is probably the part you're ...
D&D doesn't account for equipment wear
D&D 5e does not have any general rules (outside of things like Rust Monster) for equipment wearing out or being damaged. The feat neither introduces such a mechanic nor negates it.
If you (or your DM) would like to add such rules, you are into house rules territory. As with all house rules, make sure to ...
Ask Your GM.
There are debates on the subject here and here with no clear consensus, and AFAIK there's no official ruling.
It might depend on where your fast healing comes from. If it's from a spell like infernal healing, you could definitely argue that it counts as "magical healing." (Fast healing is in no way considered "resting," since it works even in ...
