I understand that in numenera players roll against an enemies difficulty level, but when using a cypher is that the same type of roll.
It makes sense for one time cyphers like an explosive grenade throw could be a speed or might dc check.
What about cyphers that are multiple rounds like the Overwatch Slayer that does level + 2 damage for level rounds. Does the player roll each round to hit the enemy against its DC and if so can they spend effort etc to hit? If they don't roll each round is the damage just automatic?
