Isnt dread ambusher first attack only?

 dread ambusher lets you make a bonus attack with extra damage if it hits.

With Mobile + Dash + Haste + Winged Boots, my character can have a 160 ft fly speed sometimes lol. Actually with Athlete with the climb speed and a racial swim speed, he can run, swim, and climb that fast too heh heh. 80ft when Haste isn’t available isn’t shabby either. 

Can I cast this, then immediately drop my concentration on it in the same turn to cause the target to lose its next turn?

if someone with an Extra Attack has haste then they have 4 attacks per turn. If they are able to use Action Surge then they could get 6 attack's that turn.  That the only good I see from this spell.

How to break game, boss style:

when facing a boss, make sure to plan beforehand with the players, so that they go along with the plan. Make extra sure NOT to have your DM there, because there's a good chance they'll ruin the fun by ruining your plan, and it's always fun to subvert expectations.

When you encounter the boss (which has to be sentient enough to understand what you're saying), assuming they have a reason to believe you, simply say "you know, I think I agree with this guy. I'm going to join him." Either you go along with the rest of the plan as follows, or follow up with "..... I'd like to roll deception."

If/when he accepts what seems to be a betrayal of the party, initiative will be rolled with the rest of the party now against both you and the boss. Cast this spell on said boss.

At literally any point that this spell is still up, drop concentration, ending the spell. The boss will not be able to take another action until the end of their next turn.

Since there's almost no way your DM planned for this, watch as their jaw drops to the floor and their boss is decimated because your party got a free bout of un-challenged damage.

You have now officially beaten D&D (or at least this single boss)

Then, on the next boss, you realize that they have a +20 to insight and you roll for deception... and fail to their impossibly high DC, because the DM is tired of your sh*t.

Or you could just use Command to do the same thing, which is a 1st level spell. They need to fail a Wis save but that seems just as / more likely than pulling off that obvious deception. And either way, not game-breaking.

when did they remove the speed double 

1 Action = 1 Attack round if you have multi-Attacks with that weapon you still get it?  this is badly worded. 

ok

You could cast this onto the the heart of something, then just end the spell, and whoopsies, they just got cardiac arrest as their hart simply refuses to beat for their next turn. If it doesn't kill them it will at least seriously mess them up and incapacitate them.

How do you track this if someone else casts it on you. If you're a barbarian or monk that usually doesn't use such spells, but a wizard casts it on you or you use an item, how do you add it to your character to track it?

 30 seconds is meant to be a round of turns. So it's easy you just have 2 turns with haste then miss a turn. 

It gives you just one weapon attack, independent of any other attack actions you may have, so you could use a multi attack follow up with that haste action to make one attack, then if you meet the necessary criteria (light weapon for two weapon fighting) make the bonus action attack as well. 

Hope that helps

- what is the bounds for a willing creature -

If i had the war caster feat, and i cast haste. then on my turn couldn't i end the casting of it ?

If i cast this as a reaction to someone moving out of my range then as long as they accept it, wouldnt the spell work ? 

would an anti magic field prevent the exhaustion part of the spell?

Get this, I multi-class paladin and rogue to get cunning action and the find steed spell, the party spell caster casts haste on me, I'm on my warhorse with 60 ft of movement now doubled to 120 ft, I take my movement, my action to dash, my haste action to dash, and my cunning action to dash, and boom I've traveled 480 ft in a single turn.

Absolutely! You would have to befriend your enemy so they are willing, cast haste on them and then drop concentration immediately (which can be dropped at any time) at the start of their turn. This will cost them two turns. RAW;

"When the spell ends, the target can't move or take actions until after its next turn, as a wave of lethargy sweeps over it."

Meaning the first turn has been cancelled and so has the next turn.

 Thanks! Ok, so would this work?

1. Charm, or otherwise make the target willing.
2. Hold my Action to cast Haste at the beginning of the target's next turn.
3. On the target's turn, cast Hate, and drop concentration immediately (when dropping concentration can happen seems to be a DM discretion thing, based on my Googling, but I'm curious what yall think).
4. The target loses the turn they were about to take, as well as their "Next" turn

That seems like the way to cost them two turns, but also seems like a really friction-y interpretation of the rules, haha.

Tooth haste

Ok just asking for clarification. I have a lvl 20 character that for the fun of it goes nearly 200m faster than the speed of sound. but am limited as i'm unsure if the range of haste needs to be constant or only when cast. can somebody please help?

This spell can be great for spellcaster Classes who want to have some martial viability, Use your main action to cast a spell. Then use your hasted action to attack with a melee weapon and then run away with double movement. Bonus points if you have mobile feat for no oppurtnity attacks.   

bard should get
