Can you have more than one skin?
 

Barkskin, Stoneskin, Ironskin. If you have one of those effects, and then get a second one, does the new one overwrite the old? Both in terms of the amount of protection you get (10,15, or 20, respectively), and in terms of the vulnerabilities you get (fire, cold, lightning)?

Strength of Gaia says that gives Barkskin. If they do overwrite, then presumably SoGaia would overwrite Stone or Ironskin. If you cast them in the other order, Stoneskin overwrite the Barkskin part of SoG? But hopefully not the other parts of SoG (natural regen, +1 nature)

Interesting question.

There is a discussion of it now on the IRC channel. Probably someone will test it. I would guess that some overwrite others.

Re: Can you have more than one skin?
 

I once tried modding a spell that gave barkskin, stoneskin, ironskin and invulnerability in a single spell. IIRC, only the two "top" spells in that spell took effect and the protection value was decided by the better spell. So the spell basically gave affected units the protection from invulnerability and the the negative poison resistance from invulnerability and the negative shock res from ironskin.

Based on that, I'd say that casting SoG wouldn't overwrite your previous stoneskin/ironskin although it would give the fire resistance malus. If I were you, I'd test it first though before trying it in MP or something.

Re: Can you have more than one skin?
 

I think the consensus is, that you can have Invulnerability up with one previous buff. Everything else overwrites.

Re: Can you have more than one skin?
 

the lord of the wild with E1 has protection of 14: basic 3, earth magic +1, his default scale mail cuirass +10.

If he casts barkskin, his protection will be 18. I dont get it at all. shouldnt it be (basic 10)+(em 1)+(cuirass 10)=21?

casting stoneskin the next turn will get his protection to 22, and casting ironskin after that to 26. (??) please enlighten me.

btw only the latest resistance malus applies in this case, just tested.

Its the same for cbm or not.

Re: Can you have more than one skin?
 

Ok:
1: Natural protection and armour protection don't just add together. There's a formula combining the two that gives diminishing returns.
2: Only the latest malus applies, except in the case of Invulnerability, where the malus is in addition to any other malus you've given yourself through Xskin.

Re: Can you have more than one skin?
 

Does that also apply to the vulnerabilities from the Mass versions of the spells?
(Protection, Mass Protection, Marble Warriors, Army of Gold/Lead)

Re: Can you have more than one skin?
 

It does for the mass barkskin from End of Weakness, but that was the only test I did on th mass spells. It would be a slight leap of faith to assume the same happens for all other mass skin spells.

Re: Can you have more than one skin?
 

OK, I went and tested it.

First of all, if you script Stoneskin, Barkskin, the spell casting AI will look at you like you're an idiot and cast something else.

Using Strength of Gaia instead, it turns out that regardless of whether you cast SoG,Stoneskin or Stoneskin,SoG, you end up with the same effect: protection 15 and cold vulnerability. So it appears that the higher-protection skin always wins.

Re: Can you have more than one skin?
 

IIRC, the vulnerabilities of all skins stay in effect while only the highest protection bonus applies.
Try casting barkskin, stoneskin, ironskin, invulnerability. What will be the results?
