First boss concept
High under the sky, there is a place, that has been long forgotten. Guarded by the hands of faith that will strike down whomever tries to enter their sanctuary.
This place marks the entrance of the "First Boss Temple", which will eventually lead to your first major fight.
You try to sneak through, but they know where you are. They smash and swing their palms, making it impossible to enter. But you are more determined than this, and you wish to show your power and might. You fight them with all your heart and manage to step inside the sacred temple.
Once inside, you follow the trail of candles that never seem to end. Room by room, you venture deeper into the mountain, and hack your way through the grotesque monstrosities that jump at you. Just when you think your journey would never end, you lay your eyes upon a large hall, filled with people who all seem to worship one soul of a peaceful man.
This is where it gets interesting. (Phase 1)
You walk closer and realize that these monks are long dead; only preserved in their last prayers. As you walk up the aisles, you get this odd feeling of not being right. Not a moment passes by, when the head of the monks opens their eyes and unleashes their horde on you. You immediately jump back and try to evade the attack of these guardian statues. They seem to fall easily, but the more you hunt down, the more stronger they get. Just before the last one falls, all the praying monks reanimate and take up arms.
(Phase 2 & 3)
While you are fighting for your life, their leader starts to chant. Rocks of all size and shape starts to fall, some hit close and some outright fly at you. But you manage to stay alive, and go after your prey. That is when they stand up and unleash all their wrath. The walls start to collapse, as you battle till death. The weaker they get, the more problems you encounter: the gate behind them slowly starts to open, whilst unleashing beasts from another world. You have no time to ponder about, and only focus on your target ahead.
(Phase 4-ish)
Finally, you sever their head and they fall to the ground. The gate is fully open now, and your energy is low: There are just way to many to deal with. You try to think of a solution, to close the gate for good. You grab a candle and lit the monks on fire, in order to keep those beasts away from you. Inadvertently, this frees their energy and destroys the gate. You feel tired and proud as you sit down on the cold stone. But as you take a breather, you hear a great rumble, from a distant world . . .
Afterthoughts
As you can see, this is just the very basics of a possible boss encounter. However, it is not without meaning. These gates hold the key to the world, and by destroying them, the player "unknowingly" creates a chain of events, which they will have to face later on.
[Would add that the environment would be more-or-less destructible, and either used to your advantage or against you--as in most of the game. And also The Sacred Monk might throw you around . . .]
Also, took some time over the weekend, and spruced up the logo for EOTH. At least it now looks a bit more authentic!
