to parry or strike since things will pass right thru it will the
arrows go thru armor and hit the target or do they impact the
armor first
and would giving the arrows more damage every other level be
to over powering like level 1-1D4 , level 2-2D4 , level 4-3D4
ect thoughts on this would be great
Greetings and Salutations. No, that limitation is of the Psi-Bow. It would do no damage if used to strike, passing through armor and body. The Psi-Arrows, even though they are psychic energy, still hit armor then body, attacking the physical plane. Consider it akin to firing a laser, but psychic energy instead of light (just something to compare it to). Light is light, and you can pass through it, but if focused it can do damage (like a laser beam). No, I didn't think of it as light when I wrote it, but it's something I came up with now for imagery. I mostly did it so it won't become a substitute for a Psi-Sword (my truest motivations). The Psi-Bow works best when you don't have another bow to use, and for increased accuracy (provides a +1 bonus to Psi-Arrows).
As for overpowering, it really depends on the type of campaign someone runs. For most of mine, I could see it easily being overpowered (though I tend to run lower powered games ... unless I'm letting the players be dragons and godlings and the like in which case it gets powerful very fast). And would all three selections go up, or would it be reduced to just one type of arrow? Because if it goes up one die each per level, at level 15 the currently 2D6 Psi-Arrow would be doing 16D6 (between 16 and 96 points of damage from just one attack) ... or if you're adding the current number each level 3D6x10 (between 30 to 180 damage). That sounds rather high in my opinion, unless it's a very high powered campaign. Now, if only the 1D4 arrow it starts off a bit weaker overall, but at level 15 it would be 15D4 (between 15 and 60 points of damage), more reasonable in my opinion, but more powerful than most psionics (a couple magical spells can compete). Most adventurers can still take a hit or two (depending on character and the damage rolled). It'll hurt, but level 15 is fairly impressive itself.
If you feel it is too limiting as is and want more options, then I suggest as an alternate idea is at various levels it provides a new type of arrow to be unlocked. For example, at levels 4 an 3D6 arrow is available, level 8 can make a 4D6 arrow, and level 12 a 6D6 arrow. This is just a random idea that came to mind as I read your question, offering a potential possibility for what I believe you're seeking. I didn't figure out the specifics for I.S.P. because it was just a quick idea (and not sure how you feel about it). If you want, I can fine tune it more for you.
Random Thought: As I looked at my own article to ask I was thinking about something Ahulune commented on earlier about the I.S.P. cost. If I had thought about it before I wrote the article I may have made wrote it in, but I didn't think about it at the time and only thought of it like a minute before I started writing this message (I haven't looked how unbalancing it may be, but at an initial thought it doesn't seem bad). Any Psi-Arrows fired from a Psi-Bow cost half the I.S.P. cost. However, when used with a standard bow (non-psychic) they are at full cost. This gives a bit of added reason to use the Psi-Bow and can make it more affordable as well. Just a random thought.
All right, I think that should be all. Hope that helps. If there are any questions please feel free to ask and I'll do my best to respond to it as soon as possible. Also, just because I wrote it doesn't mean others can't answer and give their opinions as well, and their views are equally as important. Please have a nice day, farewell and safe journeys to all.
