How would you plan out a dungeon to keep it interesting?

“@DizzyKamil: How would you plan out a dungeon to keep it interesting?” Make it asymmetrical and nonlinear (many decision points).

I spoke with @JeremyECrawford about choosing precisely what ended up in the newest edition of Dungeons & Dragons #DND http://t.co/tXaRLXcs2x

@MikeLloyHey man, Arcane Archer feat removed before PHB release. Wondering if rebalance/update planned for future. Love the flavor. yeah, it's a nifty concept. definitely something that would be good to see in the game.

@WolfHunter83 I'd ask @wotc_rodneyWhen creating a monster, how should I determine the damage output from an area effect? Should I consider at least 2 hits? that one – he does a lot of our monster system stuff

@WolfHunter83 @mikemearlsHi! When creating a monster, how should I determine the damage output from an area effect? @mikemearls advised me to ask you. It heavily depends on the spell, but usually assume 2.5 targets for anything fireball-size or smaller.

@WolfHunter83Firearms with the “Burst Fire” property should be considered like area effect attacks (2.5 targets)? Thanks for your help!! Probably a reasonable assumption.

PHB p85 says Divine Smite max 5d8. Crit on level 1 smite vs fiend, 6d8 (2d8 + 1d8 fiend bonus, x2 since crit) or 5d8?

@MathPhDwhoplays a crit would ignore any caps imposed by the special ability. you can pump it up to its max, then let the crit add on

@Zarniasdoes the Magic Initiate feat add the 1st level spell to your spell list (or spells known)? Yes, believe it does.
