@Shoruke: Regarding the ignition of Entangle spells, no. Most Instantaneous fire spells say that they are too brief to actually light anything on fire anyways; living plant material doesn't burn so much as smoke for a while, then burn; The Entangle spell is Druid-EnhancedTM living plant material, so if you do actually light it on fire, it's probably hot enough and been burning long enough that anything in the area without high fire resistance/fire immunity is most likely crispy.
-Ancestral Relic is fine, I suppose; However, the item's original price factors into the relic cost on the table
-Mithral Shirt is, in fact, exactly the same as a mithral chain shirt, except for the fact that it weighs two and a half pounds less. Just take a mithral chain shirt and call it a mithral shirt. If two and a half pounds is going to kill you, you better hope I don't send something that can reduce your strength.
-The spider domain is fine, assuming you can find a drow cleric to steal scribe spells from.
-Looking up darkstalker very soon
-Trickery Devotion is fine, except that it doesn't get the progression. It's an unseen servant/silent image 1min/level per day, nothing fancy.
@Grek
-Nope, Obscure Personal Truename does not include you
-Whisper of Fire is effectively a cantrip; The main rule is that sneak attacks require an attack roll (thus, acid splash, but not magic missile, could be used to sneak attack). Since Whisper of Fire has no attack roll, it cannot be used to sneak attack
-Automatic failures on a natural 1 apply only to saves and attack rolls; the same goes for automatic successes on a natural 20.
-I may consider allowing a feat to take ten on truespeak checks in stressed or rushed situations (such as combat).
-Characters may start out whatever age they wish. If you want, you can be Venerable with a year to live.
@others:
-Tools that take up item slots (such as a particularly intimidating mask) take up those magic item slots. Just letting you know.
