One use skill bonus item prices

[LordAsreil]

I've been looking through magic item creation specifically at items that give skill bonuses. Now the usual is the Bonus squared x 100 gp, but thats for a continuous bonus.

What do you guys use for pricing on Single use skill bonus items? I'm thinking of the potion of Bluff +20 Haley uses in the OOTS.

It would work out at 40,000 gp for a continuous +20 bonus but how much for a single shot like a potion?

[Heliomance]

That's not a potion of Bluff +20, it's a potion of Glibness, and uses the standard potion rules.

[SowZ]

Potion of Glibness is +30 and in 3e is woefully underpriced at 500GP.

[Greenish]

MIC has Skill Shards, which are one-use skill boosting items. That's 50 gp for +2, or 300 gp for +5.

Cheers for the info guys, I'll keep the Potion of Glibness in mind, making a Bluff heavy malconvoker.

The skill shards are kind of what I'm looking for but there isn't a base formula you can use for other bonuses, say a +8 or +10 to my Spellcraft or Knowledge, or any other skill, when I need it.

Buts thats something I can homebrew with the DM when it comes to it, the basic ones will do fine.

A potion of guidance of the avatar is dirty cheap (300 mo) and gives a +20 competence bonus on a single skill check within 1 minute. It works for any skill check, but I think you could get a price discount if you want to craft a potion that works only for a single skill (or group of skills). This last part is not RAW, so talk with your DM.

The formula looks like it should be somewhere between 12 and 12.5 X bonus^2. I would go with 12 for simplicity, and round to the nearest increment of 5.

2^2*12 = 48
2^2*12.5 = 50
5^2*12 = 300

I would suggest you avoid guidance of the avatar and divine insight unless your DM is used to high op. They are... horridly misleveled spells.

I built an artificer once who could get +40 to any knowledge check and treat it as trained. The DM smiled and said no. Just no.
