If you have the ability to make multiple attacks in a round, they can be against the same target or another target unless the specific ability prohibits it. You can move between attacks, as mentioned on page 190 of the PHB.
How does multi attack work?
Multiattack is just a special action a monster has that does what it says and otherwise follows all other normal rules. If it lists 3 weapon attacks, it makes each of those attacks separately with their own attack and damage rolls as normal and can attack different targets and move between attacks.
Can you split up extra attack?
Yes, you can! Yes, you are able to move in between your attacks. From the basic rules (emphasis added): If you take an action that includes more than one weapon attack, you can break up your movement even further by moving between those attacks.
Can a spell have more than one target?
Some spells can have multiple targets, like eldritch blast (at higher levels) or scorching ray. Eldritch blast (PHB, pg. 237) says: The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones.
What happens when you grapple with more than one creature?
Creatures that are one or more size categories smaller than you count for half, creatures that are one size category larger than you count double, and creatures two or more size categories larger count quadruple. When you are grappling with multiple opponents, you choose one opponent to make an opposed check against.
How many opponents can you grapple in one round?
Up to four combatants can grapple a single opponent in a given round. Creatures that are one or more size categories smaller than you count for half, creatures that are one size category larger than you count double, and creatures two or more size categories larger count quadruple.
When do you get more than one beam in RuneScape?
