can you have 2 beams of eldritch blast of you are multiclass 5th level total, 2nd level warlock?

Quote from Michaelaeus >>

So, if a warlock has Advantage and uses it to cast Eldritch Blast at a level where it has multiple beams, do the individual attack rolls for each beam get to be rolled twice or just one of them?

 no attack rolls needed for eldritch blast mate

Why bother multiclassing?  Just take Spell Sniper at 4th or as a Variant Human...  By fifth level you can shoot two rays an action, or four rays twice a day; by 11th its three per casting and you can cast six per action five times a day... congrats you have more ranged attacks per than straight fighter or ranger.

 Lol what?  " Make a ranged spell attack against the target" and "Make a separate attack roll for each beam.".  But to answer OP question, it depends on the type of advantage.  Some types provide advantage for the first attack after the triggering effect and others provide a blanket advantage to all attacks.

Example of one time advantage is Distracting Strike from the Fighter's Battlemaster subclass:

Distracting Strike

 When you hit a creature with a weapon attack, you can expend one superiority die to distract the creature, giving your allies an opening. You add the superiority die to the attack’s damage roll. The next attack roll against the target by an attacker other than you has advantage if the attack is made before the start of your next turn

Example of blanket advantage is from the Crusher feat: 

• When you score a critical hit that deals bludgeoning damage to a creature, attack rolls against that creature are made with advantage until the start of your next turn.

This spell states "Available for Warlock"

Eldritch Blast is an evocation spell and in theory an evocation Wizard would by default be able to take this cantrip because it is an evocation cantrip,....correct?

No, sorry. If you read the 'Spellcasting' part on creating a Wizard, it specifies Wizard spell list and Wizard cantrips.  There's nothing in the School of Evocation that specifically allows you to learn Evocation spells outside of the Wizard spell list.  It's the same reason Evocation Wizards can't pick up Faerie Fire or Healing Word.

Cantrips

At 1st level, you know three cantrips of your choice from the wizard spell list. You learn additional wizard cantrips of your choice at higher levels, as shown in the Cantrips Known column of the Wizard table.

Spellbook

At 1st level, you have a spellbook containing six 1st-level wizard spells of your choice. Your spellbook is the repository of the wizard spells you know, except your cantrips, which are fixed in your mind.

You can, however, pick up Eldritch Blast with the 'Magic Initiate' Feat.

"Choose a class: bard, cleric, druid, sorcerer, warlock, or wizard. You learn two cantrips of your choice from that class's spell list."

I would expect a DM to impose Disadvantage at that range, or something similarly penalizing. That's almost 2 full football fields. Perspective is thrown off. Now if it was an auto hit, or save to avoid, sure. You are still making a ranged attack roll though with EB.

 

Well, that would be wrong to do.  Both the Eldritch Spear invocation and the Spellsniper feat are designed to allow you to attack over long range, and spells don't have a Short/Long range.  Imposing disadvantage on that is a huge, and rude, nerf.  If a player wants to spend an entire Feat and Invocation on increasing the range of Eldritch Blast, they should be allowed to do so.

 

I would personally say that it would depend on how the player actually gets this feat and the type of campaign being run. If this is just a one and done, not RP heavy, or similar type of campaign, then who cares, bam they level up and can do it. If it's a more RP heavy campaign though, I fully expect the player to actually be doing something like training every day as a morning routine for a while to hit things at that range, and because of that the feat actually has meaning to it. You could still twist something to make it work with a variant human that starts with the spellsniper feat and gets the invocation later, but personally I don't think I know many people that wouldn't get something like Warcaster as their starting feat instead.

Side note, for the people wondering, DMG has a section mentioning visibility outdoors. You can see up to 2 miles (over 10k ft) on a clear day so long as your vision isn't obscured by terrain. So yeah you can see 600 ft and even 1200 ft no problem.

 Yes, you can see this far

But it would still be difficult to hit something specific from 600 ft

 

 

See it like this

A normal bullet from a revolver could travel easily 600 ft

But trying to hit something with a bullet in 600 ft distance is something else

 I think the issue here is that you're trying to apply real world senses to a fantasy setting.  One of the best ways to get a sense of how different a D&D character is from a normal person is to read the "Trained for Danger" bit at the beginning of fighter.  A member of a royal army is undoubtedly a better swordsman than I am, and those individuals are trivial compared to a level 1 Fighter.  D&D adventurers are super-human heroes (or villains) capable of trekking through arctic tundras or poison swamps carrying hundreds of pounds of gear and still walking the same speed as the 'average human' for 8 hours. If we're going to get into distances of things, take the Eagle totem Barbarian's level 6 path feature:

Eagle

 You gain the eyesight of an eagle. You can see up to 1 mile away with no difficulty, able to discern even fine details as though looking at something no more than 100 feet away from you.

This means that RAW, any D&D adventurer can discern fine details at a 100ft distance. If you apply this to the real-world scale of 20/20 vision, the average level 1 D&D adventurer can see 5x further than a real-world person with 'perfect vision'.  Now let's try and apply this to real-world archery.  Olympic archery targets are set @ 70 meters for recurve bows.  Multiply that by five and you have a D&D adventurer who can theoretically hit a target @ 350 meters.  350 meters converted into feet is 1148.29 so it's 100% conceivable that someone focusing on long range attacking could hit a target 1200 feet away with a spell.

If you're going to apply hyper-realism and apply normal real-world things to your table, then a whole slew of game rules change.

I don't know what my players should roll for a save, (the bbeg's acoliyes had eldritch blast amulets for one beam) is it like magic missile and always hits? I had the cleric roll dexterity to dodge but I have no idea. (New Dm) Please help.

 Eldritch Blast is is an attack roll so just like a Longbow but magical, if it helps you could make a lv 1 warlock with eldritch blast to work as a way to auto run the roll and damage for ease.

so like, this can detect mimics?

try to shoot the chest and:

A- it doesn't work and nothing happens

2- the chest gets shot, so you better get to stabbing

Ah, another to add to my collection!

no its pertaining to the level of warlock you are not your total level

If you're a warlock and don't get this spell, you should just eat your character sheet.

 That's true.

The spell description doesn't state you have to see the target

I was playing the campaign of a friends, I'm in a shop and down the street it's freaking civil war and the party are trying to kill each other, i go over to try and help oswald, he aims to hit Zane with an eldritch blast and accidentally hits me. At this point I'm a level one wood elf with 12 hp. I get hit, take 6hp of damage from the blast and another 5 for rolling down sharp stones in a crater. Oswald I was trying to help you. AND YOU GOT ME DOWN TO 1 HP!!!!!
