No, proficiency bonuses never stack.
According to the rules (PHB pg. 187), you can train in the proficiency of a tool or a language by spending 1 gold per day of downtime for 250 days of downtime to train that proficiency. Technically, skills aren't allowed on that list, but talking to your DM might not hurt.
It doesnt stack. Your proficiency bonus can't be added to a single die roll or other number more than once. For example, if two different rules say you can add your proficiency bonus to a Wisdom saving throw, you nevertheless add the bonus only once when you make the save.
You can take each feat only once, unless the feat's description says otherwise. The Magic Initiate feat does not list an exception to that rule which means you can only take it once.
You get 3 skill proficiencies of your choice (he picks Intimidation, Stealth, and Sleight of Hand) and 3 musical instrument proficiencies. For your race, pick Half-elf: You get 2 skill proficiencies of your choice (Insight and Survival).
They do NOT stack.If you have Expertise, taking a Feat to allow you to add double your proficiency bonus does not let you quadruple your Proficiency Bonus. Jeremy Crawford (Sage Advice) answered this specifically.
In addition, every character's Proficiency Bonus increases at certain levels. Each time you gain a level, you gain 1 additional Hit Die. Alternatively, you can use the fixed value shown in your class entry, which is the average result of the die roll (rounded up).
Skills. Each ability covers a broad range of capabilities, including skills that a character or a monster can be proficient in. A skill represents a specific aspect of an ability score, and an individual's proficiency in a skill demonstrates a focus on that aspect.
Proficiency is generally not added to damage rolls unless some feature expressly says it should. Additionally, it is important to remember that with Finesse weapons, the fighter has the choice of which modifier to use, but they have to use the same modifier for both attack and defense.
Proficiency bonus is the bonus added to checks you are proficient in (skills, saves, weapon amd spell attacks, and DC for spells and skills). The character sheet on DDB adds it automatically to these modifiers and values, so you don't have to worry about that.
At first level, you calculate your hit points by adding your constitution modifier to the highest possible total of your class's assigned hit die. (E.g. if you're a level one cleric with a constitution modifier of +3, then your hit point maximum with be 11.)
Proficiencies are determined by class, background, and in some cases race. There are times when a proficiency bonus can be modified- doubled or halved- but it is only applied once to a single die roll.
Re: Double Proficiency vs ExpertiseExpertise + double prof = 3x. You're not doubling expertise, you're doubling your proficiency bonus. Rather, that they stack additively, not multiplicatively.
Expertise is a class ability that allows a character to double their proficiency bonus on a skill. As one of the few class abilities that lets you transcend the 5e's soft bonus cap of +10, it is incredibly useful, and in a few cases it's worth multiclassing solely for this skill.
The feature "extra attack" doesn't stack. If you were a 5th level fighter and got extra attack, then took 5 barbarian levels, you wouldn't have three attacks. Just the "extra attack" for one more attack.
The 5e rules for multiclassing (PHB p. 164) state that your spells known and prepared are based on your class level for each class, but your spell slots are based on your combined levels, which may result in you having spell slots of higher level than any of the spells you know.
There's no hard limit on how many times you can multiclass in 5e. As long as you can still gain levels and you meet the pre-requisites, you can gain a level in a new class. You could gain a level in every class if you really wanted to, though it wouldn't be a good idea.
By the rules you cannot. The rules for multiclassing state: With this rule, you have the option of gaining a level in a new class whenever you advance in level, instead of gaining a level in your current class. A subclass is not a new class.
If you have both the spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the spellcasting class feature, and you can use the spell slots you gain from the
Yes. A Bard 4 / Cleric 4 can cast four first level spells and three second level spells per day (and a few higher level spells). Note that multiclass characters will often have spell slots whose level is higher than any spell that character can prepare.
Druids have a taboo against wearing metal armor and wielding a metal shield. Druids don't lack the ability to wear metal armor. They choose not to wear it. This choice is part of their identity as a mystical order.
Artificers are only half casters, and of the three subclasses, only the Battle Smith is a real standout. The infusions require a lot of work to remember, which is hard because… Second. It's in a different book.
