The find familiar spell description states:
When you cast a spell with a range of touch, your familiar can deliver the spell as if it had cast the spell. Your familiar must be within 100 feet o f you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll."
It says I use my attack modifier from my character, but what about the abilities of the familiar? For instance, vultures have the Pack Tactics trait:
Pack Tactics. The vulture has advantage on an attack roll against a creature if at least one of the vulture's allies is within 5 feet of the creature and the ally isn't incapacitated.
If I cast a spell with an attack roll and a range of Touch, and use my vulture familiar to deliver the spell, is the attack made with advantage thanks to the vulture's Pack Tactics trait?
