Converting original D&D and Mystara monsters

[Shade]

Also, see invisibility would be good, since the first description gives them that at will.

I gave 'em the same ability as the hydrax:

See Invisibility (Ex): An elemental of law can constantly see invisible creatures as if under the effects of a see invisibility spell.

Ooopsie, should've looked at the homebrews entry!

It is immune to poison, normal weapons, all 1st and 2nd level spells, and to all attacks based on air.

Krysts are immune to all earth-based attacks and...remain very vulnerable to air-based attacks, suffering double damage from them.

Immunity to spells and effects with earth descriptor?

Vulnerability (+50% damage) to effects with the air descriptor?

Again the contradiction between editions

So we go for whatever is 3.5e standard again?

Probably. Earth opposes Air.

Skills: 24
Diplomacy, Knowledge skills?

Feats: 4
Earth elemental feats: Alertness, Awesome Blow, Cleave, Great Cleave, Improved Bull Rush, Improved Critical (slam), Improved Sunder, Iron Will, Power Attack

Since these fellas are more pacifistic at most times, maybe Negotiator?

 

[Shade]

How about...

Diplomacy 6, Knowledge (the planes) 8, Sense Motive 6, Spot 4

Feats: Alertness, Improved Initiative, Negotiator, Power Attack

 

[Mortis]

Looks good to me.

CR 7-8?

I guess no treasure is ok, though they have communities. Maybe 50% gems or something?

Advancement looks good.

Hmmm. 6ft of crystals? 1000lb? Medium earth elementals are 750lb, so maybe that's a good value.

 

[Shade]

Since it only has 1 HD more than a Medium earth elemental, and only a few slightly combat-altering powers, maybe CR 6?

I agree with all the rest.
