@SymphFanFor 2weapon fighting, do you get at most 1 bonus hit a turn even if you have Extra Attacks from the fighter? (Uses Bonus action) that's correct. Since it uses your onus action, you can only use it once

@blackwarder @wotc_rodneyif a stonskined wizard is taking damage should he make a concentration check? yes, unless spell says otherwise

@blackwarder @wotc_rodneyso is it intended to be cast on the fighter and not on the wizard? that's probably your best use for it

@DarthJerodif a creature/pc has Resistance and then makes a saving throw against said resistance it is Half of Half correct? #DnD5e yes

@bandofjenkins @minipete @MerricBso how will concentration spells work as potions ? #dnd5e same way – effect ends if you lose concentration

@MerricBConcentration mechanic is really interesting – lots of effects I wasn’t initially aware of. Want to see it in play! #dnd5e I have to admit it's my favorite new rule. Cleans up stacking, makes lockdown effects and buffs much trickier to manage

@PlaguescarredWhen you crit, do you also roll all extra damage like Sneak Attack/Divine Strike again as well? Can seems like a lot yes – reroll all

— Mike Mearls (@mikemearls) July 8, 2014

@PlaguescarredCan a rogue sneak attack with a net even if it deals no damage? No, sneak attack is additional damage.

@Hadan_AshcroftWhy? This rule only limits players into just attacking. I can use a net for 0 damage or my bow for d8+5d6.. er I attack a sneak attack is *extra* damage, needs initial damage to sit on top of. DM can rule otherwise, but that's intent

@PlaguescarredThings like caltrop/ball bearings ref to moving at half speed how do you do that? Treating each 5′ as 10 like difficult terain? yes, essentially pay an extra 1' per 1' moved

@PlaguescarredDoffing armor says it can take half time with help, could a shield be doffed as a bonus action rather than an action with help? Don't see why not – that'd be more of a DM ruling thing, though
