There is no Bard class. There will be no Bard class. The new skill schools were chosen by the Kickstarter backers months and months ago. Maybe in D:OS 3. But I'll put that aside.
No one would ever use such an overpriced and underpowered school.
- That Memory cost is insane. It is way too high to be useful.
- Needing three turns to prepare a song is equally insane, that is way too much prep time.
- You are also having the song start out as weak too?
- What the heck game do you think this is, The Last Remnant? Combat does not usually last for 20 turns.
- Moving or taking any action cancels it? To repeat myself, that is insane. How, exactly, would a Bard beat the first encounter in the game? It also prohibits any hybrids. I have my doubts that you have played this game at all, if you did, you would know that the combat system includes lots of surface creation and moving.
- So... what the fuck does the Bard player supposed to do, exactly, when their turn comes around? They cannot move, they cannot attack, they cannot use skills. You have designed a player character whose job it is to literally spend the entire game pressing "Skip Turn".
- Your regen song is insanely weak. 10 armor a turn will be negligible by level 4-5. Oh wait, I have to CUT IT IN HALF IN COMBAT. Make that useless by level 2.
- You definitely have not played this game at all, because outside of combat armor regenerates to full immediately, and a bedroll does the same for health.
- Oh and Bards also become the biggest targets in any combat and being hard CC'ed ends a song. Of course I would expect hard CC would end a song, but drawing aggro from all enemies means the bard will be focused down and killed on Turn 1, which is easy because several enemies attacking one character is enough to kill them. And the Bard is not allowed to move or to do anything else.
Take this idea, crumple it up and throw it in the trash. Go back to the drawing board.
