Sir Kay is a King Arthur hero and 20,000 Prestige is required to unlock him.

Sir Kay is a spell caster, this means his attacks cannot be dodged or blocked. However, like all spell casters, he has a base chance to fail that can be improved by using the Cluster formation.

Sir Kay's strength is that he heals for an amount equal to the damage he deals. He sounds incredibly strong, but he is held back by some less visible weaknesses.

• His Magic Stat is a modest 78. 78 Magic is comparable to about 65-68 tactics or bravery.
• His innate fail rate. With cluster formation, you might land between 70% and 80% of his attacks.
• His tactics stat, it isn't high enough to grant him enough gambit defense to tank a gambit user that manages to launch a gambit attack each turn (Charlemagne & Marcus).
• Good (epic or better) Enchanted Items are hard to come by as a non-gold buying player.

Overall he is a great hero, he is very beatable and his greatest strength is in the campaign.
