Alright so Advantage/Disadvantage is roll 2d20 an take the high/low. The way its setup from the combat log seems like a 1d20 + a flat number added to your roll plus bonuses, is this correct? Besides this, there is currently from what it looks like 2 surprise rounds. Say I attack a creature, they get damage combat starts and surprise round goes I get another attack that is the official surprise round.
For sneak attacks, if I shoot from stealth or start my turn during a combat round go into stealth and attack, I'll get advantage but no sneak attack damage. I'm not sure if this is a bug or if something is off and I'm getting disadvantage also and advantage is still showing up in combat log for me.
Truthfully advantage/disadvantage seems more of a crap fest than anything I've ever read. If I have advantage on enemy i get to roll 2d20, if i have disadvantage i get to roll 2d20, if i have both nothing, if im a halfling i get another reroll on ones even if i have both. Why the hell isnt this just a flat +2/-2 from what i read the percent bonuses to the roll far far blow away any bonus from a spell. Bless why have it???
