An HP attack is when a hero gains enough energy (you see how much energy they have in a purple bar while attacking), then they use their special skill. If you have a lot, you can use them to upgrade your heroes HP attack.

Gelatinous Champion is a kind of essence that gives 3000 skill talent points.

They are also not as powerful as other heroes, even though it's a high level. It's more like an elite hero, one that has to go to the attacker completely and attack with something face-to-face.

A Paladin is some kind of knight hero, but it is not very effective.

You should also keep Gelatinous Champion essences so you can use them for skill talents. HOW TO EVOLVE YOUR HERO.I would like to take this opportunity to share to all CASTLE CLASH players about HOW TO EVOLVE YOUR HERO.1st. Without much doubt you can put Holy Conviction on basically any hero as it will give them more survivability and let them last on the battlefield longer. Keep all legendaries you get, except if they are a bad hero, such as a Paladin. There are some other ones that work on individual heroes better, please check the list below to see my personal recommendation for every hero in Castle Clash. Ordinary and elite heroes can be helpful, but some elite heroes are slow and they have to actually go right to the enemy to attack instead of attacking from far distances. Sell any heroes you don't want, such as ordinary ones. If you think that Heroes Evolved app has an issue, please post your issue using.
