Perception: used to notice something with your senses. Investigation: used to deduce something. #DnD https://t.co/7yzG3SW40v

@JeremyECrawford @bedirthan So when you're trying to deduce something using your senses or methodically use your senses ("searching")…?

— James Fischl (@JdeFalconr) August 2, 2016

Deduction = Investigation. Perceiving something = Perception. Interpreting behavior = Insight. #DnD https://t.co/aAeU0XlX7U

@pukunui81Casting ‘wall of ice’ from a staff of frost only costs 4 charges. Is that on purpose? I would’ve thought it’d cost 6. It's on purpose.

— Jeremy Crawford (@JeremyECrawford) September 12, 2016

@pukunui81d OK. That seems to be the only one where the # of charges doesn’t = the spell’s level. The staff of frost is especially good at making ice.

@JeremyECrawford Fair enough! Thank you.

@JeremyECrawford Hope you're having a restful night. Speaking of rest, will participating in 1 round of combat break a short/long rest?

— Derek Gilmore (@dmgpunk) August 11, 2016

Any amount of fighting breaks a short rest. A long rest can withstand an interruption of up to 1 hour. #DnD https://t.co/MPnqN2eDE2

@JeremyECrawford @mikemearls Curious about intent of Holy Water creation ritual. Costs the same + spell slot over buying it for 25Gp. Why?

— Airatome118 (@Airatome) September 20, 2016

A typical temple doesn't try to make a profit by selling holy water. It's sold at cost to aid the fight against fiends and the undead. #DnD https://t.co/3B4PGrCyfH

@geeniusatwrokNot even a temple of Waukeen? 🙂 A DM is free to make a temple atypical.

@JeremyECrawford Evocation Wizards ability Overchannel, Can a wizard maximise damage on Cantrips all day long and not suffer the Nectrotic D

— Kevin G (@a1104477) August 2, 2016

Overchannel was changed in the PH errata; it doesn't work with cantrips: https://t.co/vzc7twThef #DnD https://t.co/CqPWkOKY1f

@JeremyECrawford Can a Beast Master Ranger's Companion act independently (cf. Mounted Combat rules) or does it sit bemused until commanded?

— Jon (@RunAGame) June 27, 2016

If you're present and not incapacitated, your beast companion awaits your command but uses its reaction freely. #DnD https://t.co/ZGDLnBoxqI

@JeremyECrawford when one disengages, do you disengage from a specific target or everyone?

— M. Daniel Cross (@TheCrossDM) September 21, 2016

Disengage isn't directed at a particular combatant. You take the action, and you gain the benefit. #DnD https://t.co/xx5qFRRq34
