@JeremyECrawford @mikemearls Can you be wearing heavy armor and still benefit from the Barbarian totem benefits?

A barbarian in heavy armor can benefit from a totem feature if the feature doesn't prohibit such armor or doesn't rely on Rage. #DnD https://t.co/JOz9wfEkAR

@JeremyECrawford @leonegron037 @mikemearls does that mean bear, eagle and wolf can't be used with heavy, though only eagle specifies it?

The 3rd-level totem features rely on Rage and therefore don't work with heavy armor. The 6th-level features don't rely on Rage. #DnD https://t.co/xu1sCeAGD3

@JeremyECrawford Seems like you can rage in armor with no effect as written on PHB 48, so I thought bear would work. Am I reading it wrong?

Rage. RAW: you can activate it in heavy armor and get nothing from the Rage feature. RAI: Rage and heavy armor don't mix. #DnD https://t.co/4GmHuwuxKl

@JeremyECrawford @mikemearls Does the magic weapon spell work on natural weapons (thinking about beast master rangers specifically)? #dnd

— James Introcaso (@JamesIntrocaso) May 31, 2016

The magic weapon spell targets weapons (PH 146–49), not body parts. A DM can rule otherwise and not break it. #DnD https://t.co/JeMdHcg6z4

@ofthemagi @JamesIntrocaso @mikemearlswait! this would undo every fighter / druid. beast natural atks are melee weapon attacks (q.v.) See the druid's Primal Strike feature.

— Jeremy Crawford (@JeremyECrawford) June 4, 2016

@ofthemagi @JamesIntrocaso @mikemearlsyes, of course, but any precedent that says beast natural is not a weapon has breaking reach. Their attacks count as weapon attacks, but the system doesn't consider their body parts weapons.

@ofthemagi @JamesIntrocaso @mikemearlswouldn’t that mean every ftr type / drd multiclass is undone, unable 2 use ‘weapon’ abilities? Many fighter abilities rely on a weapon attack or a melee attack. Natural weapons qualify for both.

— Jeremy Crawford (@JeremyECrawford) June 5, 2016

@LexStarwalker ok. I’m still confused on when a natural weapon is considered a weapon by the rules & when not. Most of the system only cares whether an attack is a weapon attack, not whether the thing used is a weapon.

Can a barbarian hit himself to keep his rage going?

@Clint_CranfordCan a barbarian hit himself to keep his rage going? No.

— Jeremy Crawford (@JeremyECrawford) February 3, 2016

@PhoenixNorg @Clint_CranfordBut Rage continues if he takes damage? That’s correct.

— Jeremy Crawford (@JeremyECrawford) July 21, 2016

@JeremyECrawford @Clint_Cranford Then a barbarian COULD indeed hurt themselves to keep rage going. So “yes” to the original question?

— Juan Aviles (@aviles316) September 23, 2016

Barbarians can’t keep Rage going by simply attacking themselves (must be a hostile creature), but they can deal damage to themselves. #DnD https://t.co/jRUDHTBl4O

@fmacanadaguy @JeremyECrawford I've run it as yes

— Mike Mearls (@mikemearls) April 28, 2016

@G0DL1K3D3V1LSorry if this is a late question, but if said character also has Warcaster, can he cast a Warcaster legal spell? War Caster does, indeed, work with opportunity attacks, as specified in its third benefit.
