Thri-Kreen Sneak Attacker (3.5e Optimized Character Build)

From D&D Wiki

Jump to: navigation, search


The basic premise of this class is very simple. You take a Thri-Kreen, and give it the ability to do sneak attacks with many attacks. You make those attacks flat footed attacks and you deny your opponent their dex bonus to AC. You also invest in Multiweapon Fighting in order to gain extra attacks. With all these attacks, you will deal massive amounts of sneak attack dice in damage.

Combat Tactics[edit]

First activate the Wand of Divine Power (using Use Magic Device). You now have a +20 BAB.

Next, activate the Wand of Greater Invisibility (or use your ninja ability to go invisible for a round when you attack).

Finally activate the Wand of Chill Touch.

Move up to an enemy.

Your full base attack routine is as follows:

  • +18/+18/+13/+8/+3 primary hand (one +18 is a thrown weapon)
  • +18/+13/+8 off hand 1
  • +18/+13/+8 off hand 2
  • +18/+13/+8 off hand 3
  • +13 bite

Add in haste for another attack.

Note that all of the attacks besides the thrown weapon and bite are touch attacks. As well, Greater Invisibility makes your targets lose their dex bonus to AC.

You also add your dex bonus to all your attacks.

The sample here has the following attack modifiers:

  • +2 invisible
  • +1 hasted
  • +11 dex

This gives:

  • +32/+32/+32/+27/+22/+17 primary hand (one +32 is a thrown weapon)
  • +32/+27/+22 off hand 1
  • +32/+27/+22 off hand 2
  • +32/+27/+22 off hand 3
  • +27 bite

For each hit you do, you do 8d6+19 sneak attack damage (which equates to 120d6 + 285 damage since the bite will probably miss).

Your AC is also high:

10 + 11 dex + 8 armor + 7 shield + 8 deflection + 5 natural = 49

If your opponent can see invisible creatures, you are probably in trouble. It would be handy in this case to get yourself a scroll of Summon Monster IX. You can then summon a colossal fiendish monstrous spider, which has a grapple of +50. Use that to grapple down your opponent and they will lose their dex bonus to AC.

Munchkin-Size Me[edit]

If you are allowed to change the item slot of your Gloves of Dexterity, you could gain a lot more AC. With 4 Gauntlets with the Defending property, you can still do touch attacks, but also add 4x the enhancement bonus of the gauntlets to your AC. Thus +3 Defending Gauntlets (128,000 GP for the set) will grant +12 AC, bringing the AC up to 61.

When you reach epic levels, you can get Perfect Multiweapon Fighting, which grants 3 more attacks per round.
