Yes, familiar can be used for gaining advantage for allies. From Find Familiar spell description (PHB, p240), emphasis mine: Your familiar acts independently of you, but it always obeys your commands. In combat, it rolls its own initiative and acts on its own turn.
Can beholders see invisibility?
They can just move their antimagic cone first though. Worth noting a beholder’s main eye will remove invisibility (by suppression, but not ending the spell) but also make the eye rays fail. So invisibility, particularly greater invisibility, is a really potent power against beholders.
Is it good to have an invisible familiar on your turn?
It’s still good, especially if you only HAVE one attack on your turn. The invisible familiars are particularly good in ranged parties containing Rogues. Sit it next to the enemy 5ft above its head and you fulfilled the criteria for Sneak Attack.
What does the find familiar spell do for a creature?
The Find Familiar spell gives you a creature that rolls its own initiative. It can’t attack* but can take other actions as normal. One of those actions can be Help. This action gives advantage to the skill check of a creature, or can be used in combat to give Advantage to an attack.
How does a spell get delivered by a familiar?
Then on the wizard’s turn, the wizard casts the spell and it is delivered by the familiar via its reaction. On the wizard’s turn, he readies the spell and says the trigger is the familiar getting into melee range of the target.
What’s the best response to a Familiar Spell?
#1 is the correct answer IMO, and yes, that makes the familiar bait for attacks. The best response for this should be based on the intelligence of the target. A low Int creature is likely to ignore the familiar for the more dangerous opponents, at least until after the familiar drops a spell on them.
