I was wondering about something in D&D 5e:
If my sorcerer casts a spell and rolls a natural 20 against a magic user (a normal NPC or a boss), can they counterspell it?
Or is this dependent on the DM’s house rules?
Let’s say my sorcerer crits with a 6th-level chain lightning spell against a lich. Would it be possible for the lich to just counterspell and on a success rob my character of the sweeet sweet taste of satisfaction, as the air starts smelling of crispy lich and singed phylactery?
About Legendary Resistance
Legendary resistance is about saving throws, not about whether my sorcerer’s spell attack is higher than the enemy’s AC...
If my sorcerer crits with a spell (that has a spell save) against a boss that has legendary resistance, can that boss still choose to just succeed their save? ... or is this depending on the DM’s rules?
- Let’s say the target is a dragon. It still has at least one legendary resistance left.
- My sorcerer crits while casting disintegrate.
- The spell attack is higher than the dragon’s AC - the spell hits...
- A successful Dex save means no damage.
But as it’s a crit... would the boss get to use the resistance? If rolling a 20 means a "guarantied hit", the boss shouldn’t get the spell save... right?
If my sorcerer has both disintegrate and chain lightning, and the boss hasn’t spent all legendary resistances, then in general I guess it would be smarter to use the chain lightning, because a successful save would still result in SOME damage. But I'm interested in the special case of nat. 20s
(I would state which spell and what level spell slot I will be using, before I roll my dice to see if I hit, so I wouldn't be able to change my choice of spell if I got a 20, but still...)
