It’s been a while since the new boss card system entered in the Korean server.
But i cant find any video or feedback about what happened since then.
Someone tested or seen tests of the following effects?:
These 3 cards are really broken in pvp?
Templeshooter Card: Missile attacks have a [card count]% chance to silence for 5 seconds.

Kubas Card : Magic attacks have a [card count]% chance to sleep for 4 seconds.

Minotaur Card :When dealing physical damage, there’s a [★]% chance to inflict the stun debuff for 3 seconds.
This card effect works while you have the summoning skill from Sorcerer active?

Spector M (?) Card : When defeating a dark property monster, there’s a [★]% chance to recover 10% of your SP.
