In my case mermaids did not work(gob just ran through their freeze blasts), so i took witches and kicked the goblin with a timed phoenix behind my army ^^ the slow fast spawning zombies kept him away from my castle ;)
Cave of Trials 5 easy going with.
Dwarven, Goblins, Black Knights, Green Witches, Centaur archers and Zombies. You can also switch zombies with Taurus, but i did not have enough mana left.
Spells :
Heroic Strengh, Heal, Phoenix, Freeze
Just mass swarm units and support them at castle.
Other way to win is.
Dwarven, Centaur, Taurus/Shadow Lord, Meremaid, Succubus, Witches-
Just stand back, then rush with whole army to the enemy castle
looool rofl it was so easy atomrofl...
for cave lvl 5 a hero with 2900 mana.
Max lvl these cards :
Monsters :
Goblins(fast canon foder for enemy bombs)
Centaur archers (ranged bomb killers)
Zombies (slow melee boss blockers)
Dark Knights (Fast dps unit)
Green Witches (stun/knock back units)
Dwarf (dont know had no mana left^^)
Spells :
Freeze
Lightning bolt
Heal
Hero Strengh
Phoenix
Maybe there are more usefull cards, still got only 25/30.
Just push forward button all time, hit Phoenix spell tactical so the Boss is kicked over your frontal line... they will destroy the castle, while you support them max with spells. Dont try to kill the goblin. Its imho impossible. Just keep hitting the forward button ... fast spawning slow zombies +dwarves + goblins will slow down the enemy boss from reaching your castle ^^
Your hero lvls up automatically... so you dont need to do anything about this point. At different lvls you get new cards ... sometimes it works, sometimes not :P
If you complete the game once you get a second campaign option named New game Plus Cave of Trials. CoTs are extremly hard fights. When you have won an CoT you get the Boss you have fought against as a new card :D
And something that game needs, is an forced attack button 4 example the blue dragon does not attack unless he reached his target destination -.- he just fly's through the enemys....
Whats an extra space good for, if you dont have enough mana. Take the one with most mana, get 2 powerfull aoe spells + Hero Strengh + Heal in your deck. imho Phoenix rocks. Get some melee blockers and ranged. Maybe the fire demon cause he is invul while attacking.. so just move left if the enemy boss attacks right, move right side if he goes to attack the left side... and meanwhile kill him from distance...
