@JeremyECrawford is initiative a contested ability check v.s. everyone in the combat, or an ability check that determines your relative turn

The initiative roll is a Dexterity check. It's not a contest. #DnD https://t.co/jsHnlTZkZS

@JeremyECrawford followup on Initiative. Is it proficiency bonus + DEX by RAW?

— Dave Clark (@bedirthan) February 4, 2016

Initiative, like any ability check, uses your prof. bonus only if you have a feature that grants prof. in it. #DnD https://t.co/mNJkEnfIHQ

@Tsyclops @JeremyECrawford doesn't that only had to skill and tool checks?

— Dave Clark (@bedirthan) February 4, 2016

Jack of All Trades applies to any ability check that doesn't use your proficiency bonus. #DnD https://t.co/3NysYxx4vr

@ChrisPerkinsDnD the Monster stats in the Mines of Madness are different then the MM, if I'm using 5e chars, should I use MM versions?

You can use the Monster Manual stats or those in the adventure. (The players won't be able to tell the difference.) https://t.co/7cQrtEnOyk

@Anhthai_TranDo I add damage modifier to bonus action attacks (as in Crossbow Master or Polearm Master Feat?) yes, add the damage unless the attack specifically says otherwise

@JeremyECrawford Does the "Pass Without Trace" spell provide ability to make stealth check even if there is no other cover from observers…

— Kato Katonian (@KatoKatonian) February 2, 2016

Pass without trace doesn't remove the need to hide behind something or in an obscured area. #DnD https://t.co/jcWk5p6BGL
