Enlarge Person for a Dex build?

[calartnick]

I'm playing a Vivisectionist4/inspired blade 1

Basically I really wanted the feel of a guy who is pretty meek until busting out the mutagen, so having a guy start with a big strength kind of defeats that purpose. Anywho, I love the idea of enlarge person, but right now it kind of sucks for my character since i have fencing grace (no need for str for damage or to hit) and I lose out on my primary stat, however I WOULD like to get big, and I personally think it could make sense to homebrew enlarge person to increase dex instead of str.

So ideas I had Maybe...

Give +2 to Dex no penalty to other stats?
Make it a second level extract instead of first?

Thanks all!

Use Long Arm and just pretend it makes you big.

Your Dex mutagen already gives you a big Dex boost.

Yeah that's fair. Don't need enlarge person and Long Arm really.

Mind you if your GM allows it, go for it. But what I said is the best way to emulate it without homebrew.

Essentially what a Dex based Enlarge Person does:

No change in Dex (+2 Dex bonus cancelled out by -2 size penalty to Dex)
-1 Attack rolls and AC
Reach
Increased damage dice

Or, if you tweak it to give a +2 Dex bonus INSTEAD, you get:

+2 Dex (+1 hit, +1 damage, +1 AC)
-1 size to-hit, -1 size to AC
Reach
Increased damage dice

Which is actually identical to the benefits of Enlarge Person on a Str based character.

So Long Arm is actually just as good mechanically, really. You lose out on an average of 2 extra damage is all. But none of the "fitting into places" drawbacks of Largeness and such.
