Elven chain
Someone can explain me why that specific armor costs 5150 gp and not 4150 gp?

Is really +1000 gp for use the light armor proficiency or that's an errata?

And another question. Can you add a new ability or upgrade the enhancement of a specific weapon or armor? Can you make a Celestial armor +4 or a Holy Flame Tongue?

Thanks!!!!

Nonproficient with Armor Worn: A character who wears armor and/or uses a shield with which he is not proficient takes the armor's (and/or shield's) armor check penalty on attack rolls as well as on all Dex- and Strength-based ability and skill checks. The penalty for nonproficiency with armor stacks with the penalty for shields.

You can definitely increase the abilities of special magic items.
+4 celestial armor should cost 29400gp
Holy flame tongue should cost 36715gp

Elven chain gives an armor bonus of +6 so it compares to a mirthril shirt +2 not +1. Coincidentally a mithril shirt +2 costs 5100gp, seems like pretty decent pricing to me.

When you start enchanting the elven chain the elven chain really starts to shine. If you add a +1 enchantment to a elven chain would be 6,150gp versus a +3 chain shirt which would cost 10,100... the gap only gets bigger as you up the enchantment.

The obvious downside to elven chain is the max dex (+4), armor check penalties, and spell failure, otherwise it's a steal. Good stuff for a barbarian or a ranger though (though rangers are cool with medium armor now also).

I honestly think the Elven Chain entry is a mistake. Otherwise it should be 1000gp cheaper.

Elven chain is in all senses a mithril chainmail.
Medium mithril armor is price +4000gp and the price should therefore only be 4150gp by the rules for special materials.
Whet is fair and how a GM adjudicates that is another matter.
In the end it also depends on the character wearing the armor. Can they explait their dex mod. better. Do they need a low armor pen. etc...

Note: my example above was actually not very good because rangers and barbarians are better off with the cheaper mithril chainmail since they are proficient with medium armor. The big beneficiaries of elven chain are rogues and bards or anyone who is limited to light armor proficiency.

It is not a mistake, the extra 1000 gp is for the "can be used as Light instead of Medium" proficiency feature.

Thanks for your help!

I can see now than the elven chain isn't simply a chain of mithril as it was at 3.5. That I don't know is if someone will make a normal chain mail of mithril when they can do this armor for only 1000 gp more.

It's making a rule (mithril doesn't reduce the proficiency) and breaking it immediately.

Thanks again!

That is a change compared to 3.5, is it not? As I remeber 3.5 mithril it would also reduce the level of proficiency the armor required.

So Yes, in 3.5 "most" people used it ignoring proficiency.
But No, by RAW proficiency was not officially considered a "limitation."
