Question for D&D twitter about abilities and resting. Do you like a mix of some classes getting stuff back with short vs. others needing a long rest, or would you prefer everyone and everything had the same schedule? In my experience, players only ever seem to go for Long Rests. Maybe I could do more to incentivize Short Rests though. Anybody have recommendations?

I’m very liberal with making space for them at low level. My 1 – 3 stuff tends to be dungeons that lack wandering monsters, episodic travel, or more event/timeline based adventures. Higher levels, character usually have abilities to handle the risk of pausing. https://t.co/eg9bX8M1ha

I’m a big fan of abilities with a number of uses based on their primary ability score, which are then replenished after a long rest. That way, it encourages players to maximize their main ability with ASIs and (slightly) controls the power afforded to those that multi-class. Admit I love that model

That was one of the other biggest problems with 4E: monster levels had to mostly match PC levels, meaning a specific monster “fell off” of the encounter charts. I like numbers going up for their own sake, but bounded accuracy definitely helps. That was definitely a big lesson for 5e, and another area where a different approach would’ve helped 4th tremendously

@JeremyECrawford Can a blinded monster choose to attack with disadvantage on an Attack of Opportunity? i.e. following MM rules, it can "choose from the options in the Actions section of its stat block or use one of the actions available to all creatures…as described in the PHB"

If you can't see, you can't make an opportunity attack. #DnD https://t.co/5THXIvKeN6

Would this be a similar case to attacking an invisible target since you can't see the target in that case as well? A creature moving away should make noise or give some other indications of departure I would think.

Opportunity attacks require sight. That's part of the rule. The "Opportunity Attacks" section in the "Player's Handbook" (p. 195) has all the details. #DnD https://t.co/g51iJPo3HX

Ok, two follow-up questions because this situation actually came up a few days ago:
1. the Sentinel feat says that you can react with an attack if someone in 5ft range attacks someone else. No mention of "Opportunity Attack" here. Does that mean it doesn't require sight?

If something isn't called an opportunity attack, it's not an opportunity attack. The rules aren't trying to play a fast one on you. #DnD https://t.co/DO1NY6CVCS

2. The Paladin used Divine Sense in this fight with a Poltergeist(who's invisible). Would that count as sight?

— Davos (@Davos234) July 24, 2018

Divine Sense tells you a location. It doesn't give you sight. If it gave you sight, its text would say so. #DnD https://t.co/JxKQmsai1u
