@JeremyECrawfordTrying to understand monster skill formula for creating new listings. Seems clear: attr bonus + prof (maybe expertise)….
However, Lich's arcana is Int + Prof… and then a mystery +6, for +18 total. Expertise would come to +19.

@JeremyECrawford Is it intended some monsters have weird bonuses like this… or were liches intended to have expertise, and it's off by 1?

Some monsters do have ad hoc modifiers. When making your own monster, applying such a modifier is not essential. https://t.co/XS854qWRYe

@JeremyECrawford Are natural weapons considered finesse weapons? A lot of them use dex for to-hit and damage, but I can't find a reference.

— Wiliam Kerney (@wkerney) June 5, 2015

No. A weapon has the finesse property only if its description says so, and using Dex. to hit doesn't equal finesse. https://t.co/8eZIyQnVKD

@Dvergr76 @ChrisPerkinsDnD Help. PC kills mummy lord, but not heart. Takes treasure. Is PC cursed when lord comes back to life? yes. I mean, no idea what rules say, but a curse is more fun

@Dvergr76 @ChrisPerkinsDnD MM says remove curse can work, but I’d imagine the items would be cursed so they’d have to kill heart to keep. sounds good – make 'me earn it!

— Mike Mearls (@mikemearls) June 8, 2015

I'd say yes. https://t.co/0HUMWMnQ8M

@ChrisPerkinsDnD Opinions on reskinning monsters? I always feel somewhat guilty when I find myself forced to do it.

— Niklas Wiklund (@MrVojjin) May 21, 2015

Don't. It's a great DM trick. https://t.co/yTwL3yRlnu

@ChrisPerkinsDnD What challenge rating would you give Cthulhu?

— シャドーセンス (@ShadowsenseEDM) May 21, 2015

I'm guessing he's a lesser god (under the 5E definition of the term), placing him somewhere in the mid- to high 20s. https://t.co/sxODDABVAK

— Christopher Perkins (@ChrisPerkinsDnD) May 21, 2015

@ChrisPerkinsDnD @ShadowsenseEDM He's referenced in the Warlock section of the PHB as a Great Old One. So perhaps higher?

— Friar Tuk (@ahbleecker) May 21, 2015

You can't fight greater gods in 5E, as they are bodiless metaphysical beings. I guess you could fight their avatars. https://t.co/9FL7AczPlt

@daedel @JeremyECrawfordDo souls still travel through shadowfell to their final destinations? DM's call – depends on your setting's lore. I don't think there's a non-world specific answer in the game

— Mike Mearls (@mikemearls) May 18, 2015

@seanbonneyHow do you run combat with naturally invisible creatures like Invisible Stalkers? Counter w/ active Perception? Always hidden? Passive Perception to notice it works fine; not always hidden, though it can hide at any time since it can't be seen.

— Rodney Thompson (@wotc_rodney) May 15, 2015

@seanbonneyBut even if perceived, it’s still invisible, so attacks against it always at disadvantage and its attacks always at advantage?
Yep.

@ChrisPerkinsDnD 4e Question: was comparing demons level 11-20 in Monster Builder, and attack damage seems small. Shouldn't it scale up?

— Swidhelm Rozendorf (@crankydwarf) May 14, 2015

In early 4E products, monster damage was often too low. We adjusted monster damage in later products. https://t.co/V4tPgUrh7c
