The most powerful warrior.

2 Fireball
1. At the first level, among those who can guard neutral mines, the upgraded dryads are simply terrifying. Thanks to their swarm ability, they can quickly eliminate your units, especially when you're playing as the Dungeon faction....
In combination with golems, gremlins are indispensable, especially against neutral creatures.

5. At the fifth level, you forgot about nightmares; they have a good aura, they can run across the entire map, and they can attack without taking damage in return.

Inquisitors should only be used in attacks with control, to tie up enemies in combat or to absorb damage, as they are incredibly durable.

They are only effective against those who summon, and they are indispensable against Phoenix Lords and Undead, even in relatively small numbers.

In tactics involving mass attacks and mass haste, the Emerald Dragon can be more useful than its competitors, as it can attack together with dryads and dancers, potentially eliminating 4-5 units at a time, and then teleporting the trees there.

Titans (before patch 1.3, when the cost of upgrading their building was reduced) were completely useless due to their high cost; now I don't know, I need to test them again (I don't build them out of habit yet).
