@Sleylock Does a character know it’s under the effect of a hex spell? Typically, a target doesn’t know it’s under the effect of a spell like hex until it experiences the spell’s effects.

@cityratDMG scroll rules: Can Arcane Trickster and Eldritch Wizard use wizard scroll spells level 5 and up? The intent is yes, the Arcane Trickster and the Eldritch Knight can use scrolls with wizard spells on them.

@dantedipasqualeBeen agonizing & rationalizing for too long. Thanks. So a spell can’t be concentrated on & used as a reaction on turn 1? A DM could allow that, but the intention is that Ready is for the second-by-second action of combat.

and I were discussing whether or not Bardic Inspiration could be used to assist in a Dispel Magic roll.

I think no, since the ability check is a component of the spell, like an attack is a component of Green Flame Blade not an attack action Bardic Inspiration can assist the ability check inside Dispel Magic. Bardic Inspiration is intentionally generous about being able to benefit ability checks of any sort.

@Sword_of_SpiritHoly symbol engraved shield counts as material component, but does holding the shield replace somatic component also? The intent is that the shield hand can be used for a somatic component if the holy shield is used to cast the spell.

@Sword_of_SpiritMinor detail, but this means you are moving your shield around to produce the somatic component, not that you are exempt? That’s correct. You still need use of the shield arm to move it while performing the somatic component.

@SlyFlourishDo some of the more unique magic items like Sword of Wounding also get a plus bonus or no? A magic item confers a bonus to attack and damage rolls only if its description says it does. @Wizards_DnD

@GunnerMcGrathHey Jeremy, love the game! Do the Defensive Duelist and Savage Attacker feats apply to a monk’s unarmed attacks? The Savage Attacker feat works with a monk's unarmed strikes. Defensive Duelist doesn't; they're not finesse weapons.

@mpetruzz Does a caster have to have LOS to their Spiritual Weapon for it to attack? If not, what if he can’t see target? The spell doesn't require you to see its target. It follows the normal rules for attacking a target you can't see. @mikemearls

@mpetruzz caster could leave the room and leave a spiritual weapon floating in the doorway for a minute w/ disadv to hit? Yes, assuming there's actually something there to hit. The weapon could be swinging at the air. @mikemearls
