At level 28 there is not really anything you can farm as far as companions go.
you need to be a level 5 mage and a level 5 knight and then you travel to the paladin order on the map
You can either level up or if example paladin or side paladin armors you will need a paladin coin thing.
Paladins have access to two class mounts, and both are ground mounts. The first mount is the level 20 mount. This is learnable from your paladin trainer and all you need to do is learn the spell, you will also learn Apprentice Riding along with it. This mount is a 60% speed mount. Meaning it is 60% faster than running speed. The second mount at level 40, is the epic version of the level 20 mount. Also learnable from your paladin trainer, this requires you to learn Journeyman Riding first. This mount is a 100% mount. NOTE: Dranei and Tauren will receive racial alternatives to the mount that Humans, Blood Elves and Dwarves receive. This means that Tauren will receive a Variation of the Kodo and Dranei will receive a variation of the Elek. All other paladins will receive War Horses and Chargers.
You have to be a level 5 knight and mage, then go to Paladin Order
Paladin armor is for free and member. There is a cheat you can do. You also have to be level 10 warrior and healer to use it.
For a Paladin to be able to wear plate armor, they need to train for it at their trainer when they reach level 40. Before level 40, they can not wear plate.
It is available to characters who have completed the paladin flag quest after attending level 30 with at least one job
You don't have to have a certain level. You have to have all the moves on both paladin and necromancer.
You have to have level 10 healer and level 10 warrior. Hope this helped.
You cannot go past rank 10 in ANY of the classes, but when you reach level 10 in warrior class and level 10 in healers class you can become a paladin, just go to artix in the inn inside of sword haven, becoming a paladin will unlock his shop, and there will be enhancements for paladin class.
Level 10 Warrior (or Warlcok), Level 10 Healer (or Acolyte), and Membership. After, go to Swordhaven and enter the Inn there. Talk to Artix and begin his quests. Finish the last quest and he will give you Paladin.
I suggest going to UC and search for quests ur lvl their
