Because obtaining magic items isn’t up to the thief. The power and flexibility of the Use Magic Device feature is entirely up to the DM. If the DM doesn’t give many (or any) useful items that the thief can take advantage of, then Use Magic Device is not going to be a particularly interesting feature. Use Magic Device is not overpowered because the player can’...

You can make a single weapon attack with Haste Let's look at your quoted text for Bladesinger: Starting at 6th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. Moreover, you can cast one of your cantrips in place of one of those attacks. This feature does NOT say you can cast a cantrip with any extra attack, ...

Darkvision Class Feature with Cold Resistant Race: Twilight Cleric 1st level (Always on, 300 feet) The Twilight Cleric feature Eyes of Night gives Darkvision: You can see through the deepest gloom. You have darkvision out to a range of 300 feet. In that radius, you can see in dim light as if it were bright light and in darkness as if it were dim light. ...

In order: Cast Booming Blade to attack a target 5 feet from me Yes. There's no issue here. Forego my second attack to cast Shocking Grasp This will not work. Per the rules on the Bladesinging wizard's Extra Attack feature (Tasha's Cauldron of Everything, pg. 76): Starting at 6th level, you can attack twice, instead of once, whenever you take the Attack ...

It makes no difference Let's look at two situations: You use the Attack action You choose to use one of your attacks to cast a cantrip, as you are allowed to. Now you can choose to make a second attack, but nobody forces you to do that: You can attack twice, instead of once, whenever you take the Attack action on your turn. You take the "Cast a Spell&...

Enemies attacking with advantage lowers the value of AC boosts, especially in the mid-ranges. It does not remove the value entirely. Zerohitpoints made a helpful graph of what the probabilities look like when rolling 2d20 and taking the highest. Most enemies have a decent attack bonus, with even CR 1 foes having +3 or more to hit. At higher levels AC does ...

Eldritch Cannon is not an artificer spell. This is pretty straightforward: the all-purpose tool increases the spell save DC for your artificer spells, and your Eldritch Cannon and all of its features are not artificer spells. So all-purpose tool will not affect the DC for your Eldritch Cannon. A feature can increase your spell save DC without specifying it ...

The temporary hit points would remain They would remain, as per the general rules for temporary hit points. These are given in chapter 9 of the Player’s Handbook and Basic Rules, at the end of the section on damage and healing. The very last paragraph about temporary hit points states: Unless a feature that grants you temporary hit points has a duration, ...

Yes, it’s still your pact weapon The weapon ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. None of those things happened? It’s still your pact weapon.

Specific Beats General: "One Weapon Attack Only" The Bladesinger is less specific because it is talking about any generic Attack action, be it the action of the turn or from an action surge (if multiclassed fighter) or what have you. The Bladesinger feature reads "whenever you take the Attack action on your turn." That is less specific ...

Yes, you can cast a cantrip (one that requires an attack roll!) From the echo's space in this situation. You hit the nail on the head by looking at that other question. As long as it doesn't say a specific type of attack, anything that requires an attack roll will qualify. And because an attack cantrip is an attack you make with the Attack action as a ...

The haste spell's additional action cannot be used to cast a spell or to use any bonus action The haste spell states: Choose a willing creature [...] it gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action. [...] The haste spell does not ...

Casting scrolls with UMD is likely to fail UMD lets you ignore "all class, race, and level requirements on the use of magic items", but don't forget there are often other requirements for magic items. You mention spell scrolls, for example they have the following rules: If the spell is on your class’s spell list, you can read the scroll and cast ...

When features require concentration or end when falling unconscious, this is explicitly stated Let's compare the Rune Knight's Runes to the Ring of Shooting Stars, the Draconic Sorcerer's Draconic Presence feature, and the Quasit's Invisibility action: [...] The spheres last as long as you concentrate (as if concentrating on a spell), up to 1 minute. [...] ...

No. It isn't the size of the cannon that counts... it is how you use it. The cannon has 3 types of activation and the one you are probably thinking of is Force Ballista, which says: Make a ranged spell attack ... A ranged spell attack does not qualify for sneak attack. The other types of activation are even more obviously disqualified from sneak attack.

TLDR; I kinda screwed up. Yes, it is always true that AC points are less interesting if you're being hit with advantage. I have posted an earlier answer that I want to correct. While the maths in it are correct, they are not actually taking into account what is most relevant for the game mechanics (I want to remind that I am not a dnd player). I will in this ...

If your DM allows, you could swap Tiefling fire resist for cold resist, like Jester on Critical Role. (The backstory reason was the mix of her father's traits with her mother's standard-Tiefling traits.) Her Hellish Rebuke also deals cold damage. Tieflings have darkvision built-in. This is of course not strictly RAW, essentially homebrewing a Tiefling ...

Excellent answers. I just want to leave this here as a quick perspective The entire magic item system itself is balanced by several points - attunement slots, uses per day, charge consumption, and rarity. Doing away with class restrictions only bypasses one point of balance (and does so at the cost of an alternative subclass feature). Say you have an uber-...

An Artillerist Cannon is not a weapon, hence it does not qualify for Sneak Attack. The rules for Sneak Attack says (emphasis mine): Beginning at 1st level, you know how to strike subtly and exploit a foe’s distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack ...

The weak case for no For the record, I agree with the answers stating that a broken pact weapon is still your pact weapon until you do one of the three specific things that ends that status. That is certainly RAW. However, as in any enterprise where the categories are imaginary, D&D has a general 'Ship of Theseus' problem. Would it still be your pact ...

You just have to be holding the Infused Item Enhanced Arcane Focus says: Item: A rod, staff or wand (requires attunement) . . . While holding this item, a creature gains +1 bonus to spell attack rolls. It doesn't require you to cast spells through it, in fact the rod, staff or ward doesn't even need to be an Arcane Focus, just that you've infused an item ...

Neither rule is more specific than the other. The restriction "one weapon attack only" is written on a specific spell. The option "cast one of your cantrips in place of one of those attacks" is written on a specific class feature. There is no written guidance about the interaction. I think we are in rulings territory, and I would rule on ...


4

You are not forced to make the two attacks I would interpret the rules the same way as you. While based on the way the feature is written, both readings seem possible, the one when you are forced to actually make two attacks in order to cast a cantrip seems unnecessarily restrictive. If anyone would insist on the "hardline interpretation", I ...

You can make attacks with a cantrip from that space: but other features of the cantrip may not work First of all, great question! It's a very clever reading of the rules, and an interesting edge case. As you stated, the rules for an echo knight state: When you take the Attack action on your turn, any attack you make with that action can originate from your ...

Enhanced Arcane Focus cannot be used in conjunction with Alchemical Savant The simple fact is that the Alchemical Savant feature requires the Artificer to be using their Alchemy Supplies as the spellcasting focus in order to gain the healing/damage bonus, but the Enhanced Arcane Focus infusion cannot be applied to Alchemy Supplies. So unless there exists a ...

Yes, unfortunately As part of the Pact of the Blade feature: The weapon ceases being your pact weapon if you die, if you perform the 1-hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. Breaking is not a disqualifier. If you break your phone, it does not cease to be your phone. But there's more to the story You used ...

I'd say that, for RAW, this is a case of specific beats general rule. All Bladesinging Wizards of 6th level can attack twice instead of once when taking the Attack action and can replace one attack with a cantrip. But only Bladesinging Wizards under the effect of Haste spell may take another action that can be an Attack action, limited to one weapon attack. ...

Existing answers have done a good job explaining why Extra Attack only works with the Attack action, not casting spells, and that you can't cast a spell with Haste. So what can you do? With your action Attack, using your Extra Attack feature to cast Booming Blade in place of one of your attacks. With your Haste action Attack, and use your Extra Attack ...

Many abilities/spells grant temporary bonuses which might qualify, so for the sake of this post I am only included abilities which can be maintained indefinitely or are simply passive bonuses. Keep in mind the artificer infusions are also just magical items, so you could find those, but that's usually not up to the players. Gaining Darkvision: Devil's Sight -...

No, you cannot cast all three You can't cast all three cantrips in the same turn. Not because there is a rule against casting multiple cantrips in a round; there is no such rule. However, casting Booming Blade is an action that allows you to make an attack. It is not an Attack action, so your Bladesinging wizard's Extra Attack feature would not apply. You ...
