My fixes to spells

[Li Shenron]

Polymorph
Wish

...

[*]Create or mend a magic item, or add to the powers of an existing magic item. Cost: 1 XP per 2 gp of the item's value.

...

XP Cost: The XP cost for casting wish is 1,000 XP or XP indicated by a particular effect, whichever is more. When a wish duplicates a spell that has an XP cost, you add that cost to wish's XP cost.

Differentiating Xp for different uses of Wish is a very good idea IMHO. Especially for duplicating spells, the core spell cost of 5000Xp is very high (especially compared to NO cost for a priest casting Miracle).

However I think that it is a little bit too expensive for creating magic items... why should they cost 250% compared to a non-magical item of the same gp price? If you were to buy them, they would cost the same...

I'm wondering why you make those changes to fire seeds and firestorm - you make the spells virtually useless! fire seeds becomes not worth casting (compare it with an empowered flame strike... at 12th level you could do 18d6 with an empowered flamestrike in a 10ft radius or throw four acorns for 3d6 each. Wow, that's going to make a difference to foes at that level.

Similarly firestorm... a shapeable firey blast is traditional for druids, yet your version loses that key element of it.

Why did you make those changes for your campaign? Druids have a hard enough time finding useful attack spells without losing their crown jewels!
