Good bow build?

Hi, I'm wondering if this is a viable build for a sniper-based archer. The level cap atm for Toram is 40, and I get 116 stat points to allocate. My build is just DEX>CRT for a pure dmg. 90 points in DEX and 26 points in CRT(I was told that 1 point in CRT is 3 CRT Rate,can someone confirm this),I'm trying to essentially make a one shot build like an actual sniper would do. I put most of my skill points into maxing Att passives from the Battle tree and passives from the Bow tree and maxing the first bow skill. I was wondering if this was a viable or ideal build for a sniper. Comment if you think this needs work or if you think it's at the very least satisfactory, because I haven't found any real Toram Online archer builds that aren't just "Max DEX".  

If this gets any major support and feedback I'll make it into a build. Ty
