@tjfalcon1Strength of the Grave DC 5+dmg taken is a huge benefit, easy at low level, loses effectiveness at higher level, intentional?
yes – it's good for dealing with weenies, not so good for heavy hitters

@stevey @frasmageTunnel Fighter in “Defensive Stance” might have max number of AoO set at Dex bonus? Unlimited seems wrong. (idea via @frasmage) we'll see how it bears out in play – it seems really good, but mitigated since enemies have to decide to activate it

Explorers!

Master Mike realesed a generous document about character options that you can have during your underdark expedition, here the list:

• 2 new fighting Styles: Close  Quarters  Shooter and Tunnel Fighter
• New Ranger Archetype: Deep Stalker!
• Sorcerous origin: Shadow
• Warlock Patron:  The  Undying  Light

You can download this stuff here:

Gourgeous, no?

@BarantorLove Runic magic but why not make different archetypes rather than a 5 level PrC? a prestige class is open to any character – other path requires strict class/flavor links. any class can master runes

@RChiesa07A question about the talent Dragonmark (UA) : If I already own the spell that the brand gives me I can choose another? #dnd5th I'd say yes

@gaaran00bwhat classes are allowed the Mariner FS? Could I give it to a Swashbuckler? it's for any character with access to the FS feature. For the swashbuckler, maybe replace one of its higher level abilities
