Hello, everyone. Recently I've come up with the idea of having a new enemy, sort of like the Goblin King. Except this can be the Witch Queen or "Wiccan Queen"(means Queen of Witchcraft). What would happen is that at town hall 7 (Once you unlock Dark Elixir), You are suddenly attacked by a hoard of minions, hog riders, and a few other dark, troops, (Similar to the goblin attack in the tutorial). You lose no matter what, the troops are designed to be an infinite amount of health until your base is destroyed, but you don't lose any resources, and hero's do not need to regen. After the battle is over, the Witch Queen will appear, and she will give you some menacing speech about how the underworld is in her control, that she will conquer all the land, and that your base is only the beginning.
This will open up a new challenge for the player to enter a portal to the underworld, face new challenges such as bases to attack to loot dark elixir. (Note: the bases will only contain dark elixir). However, the nether portal can only be open for so long! They appear once a week, and last for 24 hours.
Should they destroy 5 out of X amount of bases, they will be awarded with a one-time 10 gem achievement. If they destroy half the bases, they get a one time 25 gem achievement. Should they destroy all the bases, they will be awarded a one time achievement of 50 gems, the Witch queen ad will appear and tell you that she will return, and then the credits will start rolling.
*This is a similar concept to Dr. Terror from Boom Beach, however you only get resources.
Thank you for reading, please leave your feedback and any ideas that you would think to improve this idea!
Idea list:
-A small chance to get a random spell from destroying a base. Spell is completely random, and you cannot get a spell you have not unlocked, nor can you get the spell if your factory is full.
-Nether bases can contain special defenses that are only available in the underworld, (similar to Boom Beach's Super Mortars).
-Nether bases can contain dark castles that contain random dark troops.
-At the beginning of the Witch Queen's attack, lighting spells will be dropped all around the player's base.
