I think you misunderstand what I'm saying. I'm not saying your character will be the tank. I'm saying the other groups will probably be pick on your character first if she is the knight. A knight is the one going for the offensive plays. Rooks can do that and tank yes but they're more limited in what they can do when compared to the knight. I could be wrong but here's what the wiki says about both classes:
While rooks are more valued they're also more of the piece that can be used for defense or offensive. They're as you say the wall. But they're not a standing castle wall they're more of a pikeman if you would let me reference ancient greece. They're hard to take down from the front and they essentially are prime targets for knights. Therefore we will need a capable knight who is capable of handling speedy but highly talented and powerful opponents. Granted my Queen NPC will be a complete badass in his own right but what I'm trying to get through is that the knight position is best filled by a skilled combatant that can handle a big enemy or at least keep them busy while the other pieces do their work. You will essentially be taking on any quicker enemy the rooks won't be able to handle. Especially other knights and priests/Exorcists/Paladins who I intend to be rather big threats in roleplay. If you believe your character can fit that role I'll give it too you I just want to make sure we got the pieces in the right places as unlike the church I don't have the luxury of just allowing everyone into their own class at will.
Well that is perfect. As a ninja/assassin (reason i keep doing this is because i dont know what culture we will be in) She benefits greatly from the speed.
Here is my idea:
Female who wields a short katana and a giant shuriken on her back which is attached to a really really really thin wire. Her ability is pretty simple. She can manipulate the energy from vibration and waves in molecules (mostly through sound). Though she cannot produce the energy to create vibrations out of nothing yet, she has enhanced hearing and along as she can hear or feel it, she can manipulate it. Now granted because she is use to manipulating sound, she struggles when dealing with vibrations and waves in the ground. Also her hearing is so good that if you were whispering from across the room, it would be like screaming in her ear. Thus she has to wear noise canceling headphones to limit her hearing
What can she do with this energy:
She can absorb the energy from sound waves.
Create weapons from the sound wave energy.
She can use this energy to block attacks but because it wastes so much energy, she can only keep it up for a second (flash barrier)
And her ultimate attack is Mute (her trump card)
-She slowly collects all the molecule energy(sound, air moving, heat, ect) in a small area, orb with 7 meter radius, to the area surrounding the orb. The more energy she collects from people talking (why its call mute), moving around, ect the bigger the orb gets. The space inside the orb becomes like a thick fluid slowing down everything inside of it and preventing sound from forming (since it is absorbed into the outer sphere). When she runs out of energy or feels she has collected enough energy, All that energy storms to the center of the orb battering around everything inside.
Now as a ninja/assassin she has one more ability. Substitution. She can switch places with any of her shurikens as long as she has a wire (or sound wire) on it and she could physically get to that space by trailing the wire. (meaning she cannot use this ability to get pass iron bars
Though i will let you be the overall judge (i am willing to remove mute if you want...)
