Crossbowman Archetype

[Grizzled Gryphon]

I was reading through this Archetype, and noticed something.

Deadshot allows you to add half your dex bonus to the damage. Greater Deadshot allows you to add your dex bonus to the damage. I don't see anything that says Greater Deadshot cancels out Deadshot, so that means 1.5 your Dex to the damage. Is there anything that says otherwise? I haven't seen anything online about this one way or the other.

Note: I am aware of the "readied action" part of all this, and realize it isn't all that good an ability, so please leave the arguments concerning this aspect and the fact that using a Longbow is superior (or not, as your opinion may or may not be) to another thread. Thanks.

It doesn't stack like that unfortunately. It will only be full Dex on Readied Actions. There is a rule somewhere and possibly on a FAQ that you can't stack the same stat on something, especially when it comes from the same source.

When the skill is an "improved" or "greater" version of a prior feat or ability, it's considered to be the same source. It has nothing to do with both applying a factor of your Dex mod to the damage as your Dex mod is the value of the bonus, not the source. But Greater Deadshot is an improvement on a previous ability, namely Deadshot so the two are considered one in the same. So you'd get 1.0x Dex to damage on a readied Crossbow attack.
