How much you got for equipment, if any?
Also, did you read Blink? It sucks.
"Likewise, your own attacks have a 20% miss chance, since you sometimes go ethereal just as you are about to strike."
That sucks. Auto 20% chance of failure while blinking? Okay 50% chance for people to miss you. You attack as if you are invisible. That's good, but that 20% failure... That's a harsh pill to swallow.
Do you have to take those levels? Could you be a 0 level non-blinking blink dog?
Okay, assuming you're gonna suck it and eat those levels. You now can cast 3rd and 4th level spells. Does your DM allow Spell-Like abilities to count for qualifying for a class? I bet that opens up some interesting PrCs. There's a reason why I make things like that supernatural abilities. Just saying.
Okay, assuming you don't want to be a blink dog spellcaster, or a blink dog druid. I just need to point out, that is some SWEET dex you got there. And if you ARE going to blink, why not take advantage of the main perk which is your enemies are gonna be flatfooted.
I'm talking sneak attack. Sure, you're gonna stack up on some weapon crystals to let you sneak attack undead and constructs and oozes and crap, but there are oodles of WSAs for Extra sneak attack damage.
But let's stick with monk. Why? The extra bites? Extra attacks? See, here's why I asked how much money you got...
Beast Claws: You can buy a pair and gain two claw attacks. Get your multi-attack on.
But Okay, lets assume you are broke. You're a Blink Dog. I'm NOT seeing you get any bracers any time soon. So. A pair of battle gauntlets. They do your unarmed damage, so they scale with your monk levels. They are one-handed, so you can wield one with two... er... paws? and do a power attack with them. You can still use your... paws, flurry of blows, yet you can stack some WSAs on them later if you wish. It takes up your hand/forearm slots, however. On the upside, it's a simple weapon, so no feats needed. Anyone who can use simple weapons can use it, which includes your first level of monk.
Now, I agree with the first two levels be monk, then move onto ToB. However, may I make a suggestion? Switch out the evasion 2nd level monk ability for Spell reflection? I know, normally, a bad choice. But if you are going to be getting your blink on all the time, which has a 50% fail rate anyways... See where I'm going?
I had a blinking Displaced wizard/rogue who had this. Nobody shot him with spells. Nobody. Even spells which normally never miss would reflect back because of the 50% miss chance for blinking and the 50% chance for displacement. It says the spell has to MISS, don't say there has to be a to hit roll.
