Eldrich Blast is 1-10 force damage plus charisma bonus of +4 for 5-14, average of 9.5 per hit. You've got to actually hit, so maybe 6 damage per shot times 3 shots will be 18 damage. But it's FORCE damage, which is rarely resisted, it's at range, and it knocks back pretty hard. The shots can be made at different targets, too. That's one hell of a cantrip! (There's also a pair of gloves in Baldur's Gate that can turn a cantrip into a bonus action. I need to play around with that to see how much it might help.)
That's for warlocks, though. Other classes can't get the +4 or knockback. They need it, too, because the warlocks have VERY limited spell slots. Those arcane restoration things that restore a single spell are a big deal to a warlock. On the plus side, one short rest and the spell slots are all restored. (Still, Wyll has a LOT of scrolls in his inventory.)
I started playing again last night. As I've been wandering through town, I haven't needed a long rest in a while. It's been nice because my main character got a buff that adds 1-6 to all attack rolls and skill checks that will only last until a long rest. I've started exploring the Soo Ehr river lately, which has been leading to more battles, so I probably should get back to town proper.
Or chewed on by mind flayer worms! How many did you end up using? What was the final quick save count?
Guido was hosting, and I never remembered to ask him how many quicksaves we used. Nothing would really surprise me. We saved a ton. In my own game, there's no doubt I'm going to trounce you

I'm a quicksave machine. I can't stop.
In my solo game, I'm using all the classes I claimed were terrible, likely because I didn't know what I was talking about. I'm playing a bard. I'm going to have a party of 6. Right now I'm thinking of Bard, Warlock, Druid, Ranger and two Paladins.
Unfortunately the game is already too easy on Tactician, so I need to look up difficulty mods. The problem, I suspect, will be in finding a reasonable one. Modder: "Game is too easy. I'm going to give everyone...an extra 9000 health!" so I may end up making my own Tactician Plus. Honor Mode is apparently the same as Tactician but without saving. I didn't really look at the custom difficulty because you can't change it once you set it.
Worse comes to worse, I'll drop one of the Paladins, and if it's still too easy, I'll drop the Ranger, but I really, really want to have a party of 6, so I'll exhaust all the options first.
I've been thinking a little about a fallen Paladin playthrough with 4 Paladins. I've never actively tried to do an evil playthrough in anything, so I'm not sure how that will turn out. As with real life evil, I can probably think up justifications for my behavior.
