Sure, the martial/exotic Great Scimitar works; just add a description to the working draft. Want to tweak it slightly, so it's not exactly the same as the Sandstorm version? Maybe increase the damage beyond 1d8 since it's Large?
Well 1d8 damage is what a M-sized Great Scimitar does one-handed, being Large the Desert Giant would do 2d6 damage, or 2d8 two-handed.
Guess we could "personalize it" to be different from the Sandstorm version. Maybe have it be a two-handed only weapon that does a tad more damage like a Great Falchion? Or a two-handed only weapon but Martial instead of Exotic?
Banded mail and a heavy shield makes sense to me, though that pushes the AC up a couple points compared to what we have projected for it. That ok with you?
A Frost Giant is AC 21, CR 9 while a Frost Giant Jarl is AC 29, CR 17, so it has +8 CR and +8 AC.
Our chieftain is +6 CR higher than a regular AC 19 Desert Giant which suggests it should have +6 AC Armour Class for AC 25.
We could forget about the shield and just make it +2 banded for AC 25, that way it's free to use its scimitar or a spear two-handed.
I agree with your treasure analysis. Dust of dryness sounds good as the magic item, though I think we should give a percent chance that it's in pellet form with water stored in it! Maybe make the Great Scimitar a +2 weapon and put a +2 enhancement on the banded mail?
Will it be a plain +2 weapon or a +1 weapon with a +1 special ability such as keen or shock?
Let's see, a +2 weapon (8300+X gp), +2 banded armour (4650 gp), and a dose of dust of dryness (850 gp) is 13,800 gp not including its non-magical gear and the weapons costs. A little over 13,000 gp but close enough.
We could throw on a masterwork hurling spear (330 gp) without feeling like the budget's being too badly shattered.
Hmm… how about making it a +1 great scimitar and a +1 hurling spear for 4630+X?
That'll leave 2,900 gp unspent, enough for a minor Wondrous Item worth 2,500 gp or so such as a cloak of elvenkind with a little left over to hand-wave away the non-magical gear and weapons cost.
Hmm… or we could aim for the 17,500 gp budget by giving the Chieftain a +2 weapon, +2 banded armour, masterwork hurling spear (330 gp), two doses of dust of dryness and a cloak of elvenkind. That's 17,480 gp.
With two doses of dust of dryness, one of them can be unused and the other a pellet of water.
Or just give the chief two doses and forget about the cloak.
