No. Per Jeremy Crawford: “The intent is that you can’t willingly end your move—any part of it—in another creature’s space (PH, 191).” A player could also ready an action to attack when an enemy is adjacent, and then perform their move.
What does the reach property do?
Increasing Reach Weapons with the Reach property have a melee reach of 2 instead of 1. Therefore you can make melee attacks against enemies that are 2 squares away from you as well as against adjacent enemies.
What does reach 5 ft mean?
147 says that a reach weapon adds 5 feet to your reach when you attack with it, which can be interpreted to mean that, if an enemy is 10 feet away on his turn, he isn’t actually in your reach (since you aren’t attacking with the weapon yet) so you don’t get an Opportunity Attack.
Can 2 small creatures occupy the same space 5E?
The rules do not state a limit of the number of creatures in a space, because 5e rules are not a physics engine. There are currently not specific rules about the number of creatures that can occupy a space. The provision is that they can’t willingly do so in combat.
Is booming blade a spell?
Booming Blade is a great cantrip for anyone who can add damage onto a single attack, can cast it as a bonus action (Quickened Spell metamagic) or reaction (Warcaster feat), or has enhanced mobility to skirmish (e.g. the Mobile feat).
How tall does a creature have to be to make a melee attack?
Most creatures have a 5-foot reach and can thus attack targets within 5 feet of them when making a melee attack. Certain creatures (typically those larger than Medium) have melee attacks with a greater reach than 5 feet, as noted in their descriptions.
Can a hero be affected by a monster attack?
A: No. Unless otherwise specified, anything treated as a hero (and therefore not actually a hero) can only be affected by monster attacks, hero abilities, and Overlord cards that target a hero. (1)
Can you force an enemy to move out of reach?
Yes, but only if the ability forces the enemy to move out of reach using their movement, action, or reaction. The rules state that only when the enemy uses their movement, action, or reaction to move out of your reach will they provoke an Opportunity Attack from you. From the PHB:
When does a creature provoke an opportunity attack?
A creature doesn’t provoke an opportunity attack if it is moved without the use of its movement, its action, or its reaction. For example, the effect of the antipathy/sympathy spell requires the target to use its movement, meaning that it would provoke opportunity attacks when it does so.
