Demons attack with a magical projectile for moderate damage, moving in for a 2-hit melee attack for critical hits. They also use the skill Fear (畏怖), which causes Critical Damage Down. Demons can act up to 3 times per round.
It takes 5 ticks to fill up a Demon's Noble Phantasm. Its Noble Phantasm, Demon's Seal (デモンズシール), does ~500% damage to one Servant and causes NP Seal (宝具封印) for 3 turns.
Demons have high HP and hit hard for their levels. Because they can execute 3 normal attacks in a row, be loose with defensive skills when you are mid-low on HP. When facing a Demon prior to boss floors, watch out for its Noble Phantasm, which, if your Servant survives, locks your own Noble Phantasm for 3 turns; the damage can be evaded, but the debuff is harder to deal with. This can throw off NP chains against bosses, forcing you to sandbag until the debuff falls off.
