After my first combat playing D&D 5E, I noticed how much trouble spellcasters can get into when making ranged spell attacks, vs ranged spells:
Aiming a ranged attack is more difficult when a foe is next to you. When you make a ranged attack with a weapon, a spell, or some other means, you have disadvantage on the attack roll if you are within 5 feet of a hostile creature who can see you and who isn’t incapacitated. (BD&D p73)
I've long since heard that the go to 'solution' is to get the feat Crossbow Expert because of this effect:
Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls.
Which covers ranged spell attacks.
But it feels like a real waste of a feat to get that when I don't plan on using crossbows, hand or otherwise, ever, with this character. And I'm doing my level best to keep this character out of close-combat.
I came across Feint Attack from the Battlemaster class:
You can expend one superiority die and use a bonus action on your turn to feint, choosing one creature within 5 feet of you as your target. You have advantage on your next attack roll against that creature this turn. If that attack hits, add the superiority die to the attack’s damage roll.
So the advantage granted would cancel out the disadvantage, and potentially add a small amount of damage. It also looks like it would work with a ranged spell attack, as this maneuver does not specify weapon attack like many of the other options.
I could hypothetically get this via a feat (Martial Adept) or a (3 level!) multiclass dip.
Assuming I have access to this maneuver, and ignoring any other benefits of either ability (like crossbow reloading, or the other maneuver(s) granted by feats and multiclassing, or making melee attacks instead of my planned spell usage), do they function the same when I'm 5ft away from an enemy and cast a ranged spell attack (like eldritch blast)?
