It doesn't have a bonus to damage from any source, such as weapon attacks and some spells do.
Eldritch Blast deals 3d6 damage at first level, which averages out to about 10-11 damage.
A fighter with a Greataxe and 16 STR deals 1d12+3 damage, which averages out to about 9-10 damage. An elven fighter with a Longbow and 16 DEX deals 1d10+3 damage, which averages out to 8-9 damage. Both these attacks are made before without Deadly Strike, which adds about 3-4 damage on average.
The Wizard's Ray of Frost, also an at will power, may not be as powerful in terms of damage (6-7 on average), but it slows people down and he has access to spells that outdamage the warlock's eldritch blast that he can use a few times per day, such as Ray of Enfeeblement (14 damage on average, 7 on a miss AND minimizes damage of target).
I don't think 3d6 damage is too much at all, it just sounds good because of all the dice![]()
Good analysis, but it actually delivers me the opposite feeling... that Eldritch Blast is way too much at will.
Another good comparison is to a rogue (thief) with a shortbow. Basically every other round (at least) the rogue gets to attack with advantage and deal 3d6+Dex modifier on a hit. 7d6+Dex modifier at 5th level.
Wait a minute... there are a lot of concerns with Sneak Attack being too powerful itself, and should be toned down. If that is going to happen, then the comparison will not be very appropriate anymore.
I think the comparison with the Fighter is the most appropriate, because the Fighter is supposed to be the fighter of the group, the guy who hits harder and more reliably than anybody else. Also because he's always going to be the character with less to do besides fighting, while the Warlock already has other capabilities.
