A tiny concern...

[CryptbornAkryea]

Tiny PC must share the same square as their target, yes?
Would a reach weapon fix that?

Nope. 2x0 is still 0.

[CryptbornAkryea]

So no real fix for it then, eh?

[Zombulian]

Well there are certain things that instead of multiplying your threatened area, just add 5ft to it. Getting Aberrant Blood and Inhuman Reach will add 5ft, as well as Will Deformity and Deformity: Tall.

[CryptbornAkryea]

Aberrant Blood? Where would I find that?

[Zombulian]

Aberrant Blood? Where would I find that?

Lords of Madness. The Willing Deformity feats should be in Champions of Ruin or Elder Evils.

[Dread_Head]

Enlarge Person or the Expansion power to bump you up a size category? Probably not the answer you're thinking though.

Use a Whip (http://www.d20srd.org/srd/equipment/weapons.htm#whip)?

The whip is treated as a melee weapon with 15-foot reach, though you don’t threaten the area into which you can make an attack.
This will give you reach although the inability to deal lethal damage, inability to threaten and inability to damage anyone wearing armour or with natural armour are pretty big drawbacks, oh and the feat tax needed to use one (unless playing a Bard). I believe there is a Whip Dagger in one of the books that solves most of these problems though.

Edit: Deformity feats are in Book of Vile Darkness, Heroes of Horror and possibly Champions of Ruin as well.

Hrm...

Any ideas on getting past the aoo provoked by a tiny PC entering an enemy-occupied square?

[Gildedragon]

Well, verily, there is a feat for that:

Don't Mind Me (http://www.wizards.com/default.asp?x=dnd/fools/20030401c)
You do need to be feline for this to work, but there is the Savage Species ritual that gives you a subtype


Or manage to get your tumble to 25

[CryptbornAkryea]

Lol, tumble 25 outta do

[CryptbornAkryea]

Another idea...
Could Blink Shirt get a Tiny PC into punching distance of his target?

[Coidzor]

It's not unheard of to houserule that away so that reach weapons on tiny creatures give them 5' reach, but by RAW, no.

Underfoot Combat from Races of the Wild. Requires 10 ranks of Tumble. It's a prerequisite for Confound the Big Folk.

The Other Killer Gnome (http://community.wizards.com/forum/previous-editions-character-optimization/threads/1059231) may be of interest to you as well. Confound the Big Folk can be especially nice if you have some way to provoke enemies into attacking you.

Also, Gnomish Quickrazors may be of interest to you combined with Iajutsu Focus, maybe.

[Bronk]

You could use the 'extending' weapon property (+1), increases or decreases range by 5’ (Dragon 302 page 66).

[Zombulian]

If you want to waste a round of action, then sure. Blink Shirt expressly forbids taking actions after your teleport. You can of course get around this with the Sun School feat, Teflammar Shadowlord, and things like Planar Touchstone and Snap Kick.

It's not unheard of to houserule that away so that reach weapons on tiny creatures give them 5' reach, but by RAW, no.

Or slightly more than houserule in Pathfinder (http://paizo.com/threads/rzs2klag?Do-tiny-reach-weapons-provide-reach#4)-land
"Game speak for "DOUBLE" doesn't really mean "twice as much." A creature that's Tiny and has a reach of 0 feet who uses a reach weapon would basically go up to the next stage of reach: 5 feet. Something smaller than Tiny would, at the most, go up to Tiny's level of reach—weapons smaller than those wielded by Tiny creatures, therefore, never have reach."
Granted, this is "forum post" level of rules, which ranks a fair bit below Errata, or FAQ even.

[CryptbornAkryea]

Is it really all that much of a waste if the PC blinks onto/into the attire of the target?

[Dread_Head]

Great Flyby Attack (SS) would also do it if you're playing a flying small race or have a way to get flight. As would Improved Flyby Attack (SS) but it has terrible prerequisites and is just generally a lot worse.

Edit: Yes because then you can't do anything on your turn (due to Dimension Door that Blink Shirt mimics) and then the enemy moves away on their turn. Or even if they don't you still lost a turn positioning yourself to attack rather than actually attacking.

[CryptbornAkryea]

Can anyone tell me it wouldn't be great fun to watch the BBEG trying to attack the PC hiding in his armor/robes?

[Coidzor]

I don't believe you're able to teleport into a grapple.

[CryptbornAkryea]

Maybe... Appear over the head of the BBEG? Land on him?

[Zombimode]

Maybe... Appear over the head of the BBEG? Land on him?

You're not grappling someone by simply appearing over the head (especially if you can't take actions afterwards for a short while).
(Also: do note that a tiny creature automatically fails to grapple a creature of medium or larger size.)

[Dread_Head]

Is pretty useless as you won't weigh much so you need fall a long way to do any damage (http://www.d20srd.org/srd/environment.htm#tableDamagefromFallingObjects) (50ft ish) but you will still take the normal falling damage (1d6 per 10ft fallen)

Whip (http://www.d20srd.org/srd/equipment/weapons.htm#whip)

The whip is treated as a melee weapon with 15-foot reach
Grafts (Fiend Folio):
Long Arm - +5' reach, 5000 gp
Whip Tail - +10' reach, 8000 gp
Raking Tentacle - +5' reach, 5000 gp

[Metahuman1]

If you could reliably work it out to have the Tome of Battle Strike Battle Leaders Charge (White Raven, Second level.) every time you needed to close with and enemy and enough movement on a charge to get you to them, you could Nix the AoO that way. And it would leave you in a square with them so that you can unload other maneuvers and attacks in subsequent rounds if they don't move away on there turn.

Get a source of Pounce, and you can even full attack on that initial charge.
