@JeremyECrawford Last sage adv don't cover when villain tries to cast suggestion and you succeed the save. Do you notice he cast something?

— Leonardo Raele (@LeonardoRaele) September 20, 2016

Do you notice a spell being cast? The answer is based on whether you noticed any of the spellcasting components: V, S, or M. #DnD https://t.co/pGdLbivnTm

@JeremyECrawford I hear rumors that you are a rules sage! Does the fighter style Dueling work with weapon in one hand & shield in the other?

— Faye Polson (@REactionFaye) September 20, 2016

On Dueling and shields, take a look at the Sage Advice Compendium, a collection of some of my past answers: https://t.co/dh02JRnEH8 #DnD https://t.co/Q1kiVWwdPr

@JKFWEBDoes Guardian of Faith, which is adjacent to the enemy and PC, attack an enemy who is attacking the PC but not moving? Guardian of faith is triggered only by movement.

@JeremyECrawford if I cast contagion on a dragon and he use legendary resistance does he pass on all 3 saves at once or just that one save

— JAck (@alicenlok) August 2, 2016

A use of Legendary Resistance causes success on one save. #DnD https://t.co/RYyjuvfjeG

@mikemearls @JeremyECrawford is the minotaur's perception of +7 correct? prof bonus +2, Wis +3, shouldn't it be +5?

— Mike K (@Jabbedxorz) October 11, 2016

@DnDPaladin @Jabbedxorz @JeremyECrawfordmonsters have expertise like rogues do ! yes, assume expertise or a bonus based on creature type #wotcstaff

Calculating a monster's skill bonus? See "Skills" in the Monster Manual (p. 8). Minotaur's Perception = Wis. mod. + (prof. bonus x 2). #DnD https://t.co/xkyxHDrPAL

@JeremyECrawford Does 'it is proficient in' qualifier apply to Beastmaster companion saves & skills or just skills? Can read either way.

— Edward Krusling (@EdKruze) June 23, 2016

Ranger's Companion: if your beast has proficiency in a skill or save, you add your proficiency bonus to it. #DnD https://t.co/bUiFB1IlyC

@JeremyECrawford What if I'm dual-wielding a dagger and a whip, can I use the dagger when someone leaves my 5' but stays w/in 10'?

— Patrick (@jd2319) October 26, 2016

If you want to make an opportunity attack with X, the attack is triggered when a foe leaves the reach of X. X = weapon you want to use #DnD https://t.co/MUcJpn4Vvr

— Jeremy Crawford (@JeremyECrawford) October 26, 2016

@JeremyECrawford Awesome! So does that mean you can always make a 5ft unarmed Opportunity Attack, IE if holding a two handed weapon?

— David (@thethain) October 26, 2016

Unless a feature tells you otherwise, you have a 5 ft. reach with your unarmed strikes, and you can make opportunity attacks with them. #DnD https://t.co/ezYaayMNuo

@JeremyECrawford One of my player is using polymorph at himself to be a TyrannosaurusRex.Isnt he abusing?Is that the intention of the spell?

— Enrique Delgado Torr (@enrikisinger) February 27, 2016

You can cast polymorph on yourself, provided you can see yourself. #DnD https://t.co/MQ0FzPkrYX

— Jeremy Crawford (@JeremyECrawford) February 27, 2016

@JeremyECrawford You can always see your hand, for example, Do you mean you need to see the whole body in order the spell to work?

— Enrique Delgado Torr (@enrikisinger) February 27, 2016

To see yourself, just look down. Something like blindness or darkness can prevent it. #DnD https://t.co/gfyXUwMhhi
