So a fighter/druid could use his action surge to multiattack twice in a round, given that character has assumed a form with multiattack capabilities, such as a bear?
Sure why not a single class Fighter with multiattack can use action surge to make the attack action twice in a round, gaining double the normal number of attacks. All those attacks happen on the characters turn.
Hmm. It depends. I'm not exactly sure what you are describing. Here is how it works.
Initiative Count
Round 1
18 Orcs' turns: Orcs move towards the players but have not yet moved through the door.
16 Elgweth's turn: Elgweth uses his Action to ready an attack "When an orc comes through the door, I fire an arrow."
15- Other characters act.
Round 2
18 Orcs' turns: Orcs continue moving towards the players, passing through the door. As soon as the first one does, Elgweth uses his Reaction to fire an arrow at it. The orcs continue their turns.
16 Elgweth's turn: Elgweth regains the use of his Reaction, and now acts normally. In this case, there are more orcs, so he starts shooting arrows at them.
15- Other characters act.
Here is how it doesn't work:
Initiative Count
Round 1
18 Orcs' turns: Orcs move towards the players and pass through the door. Elgweth takes an action to shoot them. Wrong: He can't do this because his turn hasn't come up yet (assuming this is the start of combat and there wasn't already a previous round), and readying an action is an Action you take on your own turn.
16 Elgweth's turn: Elgweth moves but doesn't act because he already used his Action to shoot the orc. Wrong: Even if this were round 2 so that Elgweth could have had his shot readied, shooting an orc with a readied attack would use a Reaction rather than his Action.
Hope that helps.
Just a reminder sometimes words like "pinned" or "restrained" don't translate to the game effects well.
Oh hey! Good call! So there is a version of pin in 5E. Basically you just need to grapple a target, then on your next turn use the shove action to knock them prone. On their turn they can't stand from prone as they have 0 speed from the grapple, and if they attack you they have Disadvantage. As they are prone, all of your attacks will have Advantage against them. Only way for them to get away from you is to successfully make a Strength (Athletics) or Dexterity (Acrobatics) check as an Action.
That is a cool find emdw45.
This is true, but as a tactical note: you can't stand up from being Prone when your speed is zero, so grapple/prone will tilt the combat decisively in your favor, at the opportunity cost of two attacks (or more) which you sacrifice to make the grapple/push prone.
We've been doing this completely wrong then. Old mindset i guess. So readying also does not change your initiative at all. You just use a reaction?
Was there rulings anywhere what happened with forms and extra attack?
Ah, you mean in exchange for it being harder to disrupt a caster initially, 5E has made it easier to recover from harmful effects without outside aid? If that's the case, I definitely agree. I have heard some people complain about the ease with which characters and monsters are able to recover from these effects, however. It's a new paradigm that we're all still getting used to. As you said, it used to be that when a spell took hold, you could be reasonably sure you'd just affected a target for a good length of time. Now, many spells are quite a bit more powerful than before, but they only last a fraction of the time (usually only a single round or two). This means we need to re-calibrate our expectations of how magic impacts a fight. Instead of being crippled all fight long, but still capable of action, nowadays many spells make it so you're out of commission for a round or two, unable to do anything, but you recover from it before a fight ends.
It remains to see how the community as a whole will come to feel about the change as we get further into 5E.
