gythka: base damage & STR damage

[Mystendanian]

according to the SRD:

*Wielding a Weapon Two-Handed: When you deal damage with a weapon that you are wielding two-handed, you add 1-1/2 times your Strength bonus.
*Off-Hand Weapon: When you deal damage with a weapon in your off hand, you add only 1/2 your Strength bonus.
*Double Weapons: You can use a double weapon to make an extra attack with the off-hand end of the weapon as if you were fighting with two weapons. The penalties apply as if the off-hand end of the weapon were a light weapon.

So, according to this, I would guess that someone using a gythka that had a STR of 20 would add only +5 to the damage with the "main" end of it and only a +3 with the "off hand end", correct? Even though they're technically using it two handed, using a dble weapon says you treat it as you were fighting with two weapons.

Also, I have now seen 3 different base damages listed for the gythka. XPH has it as d10, Savage Species has it as a d8, and MMII has it (under thri-kreen) as 2d6. Is there an official ruling on this?

off hand would be +2, always round down.

For damage I'd go with the XPH, its the only book you listed that is 3.5

To clarify, when you're fighting with both ends (ie. getting two attacks at -2/-2 using the TWF feat) you get +5/+2 damage with the main and off hands. When you're not making two attacks, you count it as a two handed weapon and do +7 damage.

The official ruling would have to be 1d10, since the XPH is the most recent book, and the only one of the three that uses the 3.5 rules.

I'd say 1d10 would be the best value, 2d6 is too much, 1d8 is crap for a x2 crit exotic double weapon, 1d10 seems about right.
