For the paladin skills, I haven’t seen the information about their skills, but i seen how those paladins use them.
When the paladin is casting a magic, they’re probably using a Calm Down skill, when its sucessfully cast, i think it deals you 1-10+ damage and it depletes All the rage you have just earned, so make sure you interrupt his/her casting time (Stomp, Charge, or Kick will do) asap.
They also can heal themselves, almost like the healing potion effect, called Healing Touch (Costs 20 rage i think), when he used both his healing touch and a health potion, you might not be able to reach-kill him down either a basic attacks or any attack skills. unless he used it below 50 health.
Lastly they can also use the defensive stance too even if they’re level 10+ i believe. just look at Skywheel’s info about it.
Thats what all i seen from the paladins i faced in every other battles.
