@JeremyECrawford @mikemearls cats and tressyms both have +0 to hit with claws, but the calculations would imply that they should get +4?

Some critters, like cats and tressym, are designed to be unusually weak combatants. #DnD https://t.co/TkNs4y8Z8W

@JeremyECrawford does True Sight detect a hidden rogue, or is perception still required to see him/her? #dnd #5E

Truesight pierces invisibility, illusions, darkness, and false forms. It doesn't pierce total cover or make you hear better. #DnD https://t.co/VWKsJGFxqW

@JeremyECrawford What printing of the core books include errata, if any?

— Louie Brogdon (@glbrogdoniv) August 2, 2016

Corrections appear in the D&D core books as of their 3rd printings. #DnD https://t.co/avPSxtprDE

@JeremyECrawford Is Abjurer’s Arcane Ward 2*(Wizard Level+Int mod) or (2*wizard level)+Int Mod ?

— Matt Petruzzelli (@mpetruzz) August 17, 2016

Arcane Ward—its hit point maximum equals your Intelligence modifier plus twice your wizard level. #DnD https://t.co/RvMi3TKYGd

@JeremyECrawford A creature in the DMG is granted a +1 magic weapon. Do I rescale its CR? If it loses the weapon, do I scale it back? #dnd5e

— TheImagineer (@IAmTheImagineer) October 18, 2016

A +1 to hit and damage rarely affects a creature's CR, unless its CR is very low. I wouldn't bother changing the CR in play. #DnD https://t.co/7R5AFSY6QC

@RobertPascuttin @IAmTheImagineerShould a monster cr be recalculated if players have magic weapons to bypass monster resistance? No.

@RobertPascuttin @IAmTheImagineer Thx! Can u explain dmg; p277; para 3 then please? Seems 2 say having or not having magic weapon adjusts CR That's referring to things like spells or class features.

@JeremyECrawford If a druid wildshapes into a wolf and is then targeted with power word kill does the druid revert dead or alive?

— Bobby the Barbarian (@BobbyBarbarian) April 4, 2016

If you have 100 hp or fewer, power word kill causes you to die. Notice that it doesn’t say you drop to 0 hp. #DnD https://t.co/MnVjACCIml

— Jeremy Crawford (@JeremyECrawford) April 4, 2016

@JeremyECrawford So what is PHB pg. 66 “You automatically revert if…..drop to 0hp, *or Die* .” telling us? Form dies, Druid reverts, yes?

— Airatome118 (@Airatome) April 28, 2016

Beast form ends if the druid dies; things like power word kill can end you without reducing hit points. #DnD https://t.co/sxcd3shfP3

@JeremyECrawford Next question, can a player jump while holding a grappled creature or does doing so end the grapple?

— Ryan Bally (@Vo1kain) August 24, 2016

Jumping is a form of movement. See the rule on moving a grappled creature (PH, 195). #DnD https://t.co/eKUCRbTdqe
