Whether you're striking with a melee weapon, firing a weapon at range, or making an attack roll as part of a spell, an attack has a simple structure.
...
If the d20 roll for an attack is a 20..the attack is a critical hit...
Yea there is no attack roll for fireball so you cant crit, they are rolling a saving throw to avoid the damage.
Fire Bolt is a single target ranged spell attack with an attack roll, so you can crit that, and it works like any crit (role double damage).
Okay! Awesome, so I did make the right call. I can't even begin to explain how much I love this magic system. It's vancian but much more free, also the "slots" don't actually feel like slots at all, more like MP per level. I never even really thought of doing it this way. I think it works because the absolute best part is that many spells can be used at higher levels. It just cuts down on the bloat. AH it's so awesome. Also cantrips got a bit of a buff which provided the 4e aspect that my wizard can still doeven though he ran out of spells. Love that bounded accuracy forced the developers to handle stuff like mage armor differently yet still getting the purpose and feel across. I just... I didn't expect to like this system as much as I do. I was completely 'meh' about it after using 13th age, but man... I think they actually did it, they made the best version of D&D they possibly could. I can't wait for the PHB, it's killing me haha.
We did the first part of the starter and cleared the cave. Anyway one thing that came up. Do spells benefit from crits? For instance I was casting firebolt and I critted. I was the DM (as well as running a wizard) and I ruled that it did.
Can you give some comments on how the session went?
Playing with new or veteran players?
Also, I was wondering the following when I watched the livestream
Spoiler:
In the livestream they captured a goblin to lead them to the cave.
How do you find the cave if you kill all of them?
