A ranger ability for striking [3.5] [PEACH]

[Teapot Salty]

At level five, once per encounter, a ranger may declare this round to be a guided strike round. At the beginning of his turn, a ranger makes a survival check. All attack rolls and damage rolls now use the survival check in place of their normal modifiers/rolls.

Flavor: Your skill in tracking has been tuned to more than lead you to your target, but lead your weapons into their flesh.

every five levels after the fifth, a ranger may use this ability an additional time per encounter.

Very new idea, what do you guys think?

At low levels, this is a nice buff for damage and maybe a to-hit buff as well. At very high levels, it becomes a self-debuff unless the ranger has worked very hard to optimize the skill check.

Your right, what if the ranger added ranger levels to survival checks?

You are seriously underestimating easiness with which you can get bonuses to skills. Masterwork item grants +2 for 500gp, you can get up to +20 for skill bonus squared * 100 gp - 10 times cheaper than corresponding magic weapon bonus, or cast Guidance to get another +20.

Unfortunately, this ability is broken.
