Warden Adaptability

The warden should be able to resist certain types of damage as he is more exposed to them, to prevent most ways of cheesing him. For example, the first time you use use end crystals on him, it does 20 damage ( I don’t know what the actual number is) but when you do it again the second time, it does 15, so less than it did before. I think this could be applicable to multiple damage types, like explosions, lava/fire, potions like harming and poison, etc. this would make it necessary to bring a variety of tools to kill the warden, and make it a more unique and interesting fight, and make it stand out more than it already does. Also, as he becomes more resistant to these attacks, there could be some kind of visual indicator that he is more resistant. For example, when he is more exposed to explosions, he starts to develop some kind of obsidian armor around himself. I think it’s a pretty neat concept.
