No, you can’t cast a spell with your extra action from haste.
Can Hallow be dispelled?
A dispel magic fixed to a hallow or unhallow spell can be treated only as an area dispel, not as a targeted dispel or a counterspell.
Can you dispel wish?
According to the rules as written, the addition of a timer to the effect of Wish does NOT mean that the effect continues to be magical. Wish CANNOT be affected by Dispel Magic; there’s no ongoing magic to dispel.
Can two people cast Haste on the same target?
If they’re cast in the same round, it’s a tossup on which one has it. If one casts on a following round, then THAT one takes over because it has greater duration. Arguably, the DM could rule that it means the old haste stopped and make the person be exhausted for the round, but nothing in RAW enforces that.
What happens at the end of a Haste spell?
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.
What happens when you use haste on a creature?
Choose a willing creature that you can see within range. Until the spell ends, the target’s speed is doubled, it gains a +2 bonus to AC, it has advantage on Dexterity saving throws, and it gains an additional action on each of its turns.
What happens when a spell ends in RuneScape?
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. Could the target still use a reaction (to, say, throw up a Shield spell if needed) or is a reaction considered a type of action?
What happens to the target when haste ends?
Since the spell depends on concentration, it could end unexpectedly if the caster loses concentration on it, leaving the target in a perilous situation. Jeremy Crawford confirms this on Twitter. @JeremyECrawford After Haste ends, PHB says target can’t move or take actions. Does this include reactions? Advantage to hit target?
