I found a way to make a Druid/Planar Shepherd even more powerful.

This requires cross-setting material and a GM who allows Leadership, but consider this.

You're a Human.  You go Druid5/Planar Shepherd2 to 5/Hathran5Planar Shepherd5-8.  (Rearrange level order to suit your liking assuming you meet all prereqs.)

With an acorn of far travel (and plane shift and teleport via plants) you can continuously renew your ability to spontaneously cast any Druid spell of any spell level you can cast!  Oh, and Circle Magic @Hathran5.

Assuming you aren't going for free wishes with Fernia or 10:1 turns with Dal Quor, you can still do lots with, say, Lamannia, the Twilight Forest.

Sure, you won't have the full Wild Shaping of a Druid20, but you can do plenty.  A Dao (Manual of the Planes 172) via Lamannia gives limited with 3/day to nongenies... like party members.  (No XP cost!)  And you can use Circle Magic to cast all your spells at caster level 40 + other bonuses.

I jokingly call this the Commander Shepard build.  And yes, this interaction of abilities (Druid, Hathran, Planar Shepherd) is powerful, and you can probably make it even more so.  Please don't remind me that this stuff is powerful/good.

Good for ya.

This is actually a pretty tame way to combine Planar Shepherd and Hathran.

Also, you can use the Limited Wishes on yourself. Wild shape doesn't change your form; therefore, you're still granting a limited wish to a non-genie.

FTFY.  Saying that it doesn't change your form is not accurate....

What's a less tame way to use Planar Shepherd and Hathran?

There's a plane that gives you infinite turns, rather than 6:1

Which one?

Anyway, you can always just make a plane with Genesis. :3

Ahem, thanks for that.

Well, Rashemi Spirit Magic lets the Hathran 'spontaneously cast any spell she knows in place of any spell of the same level that she has prepared, even if it is not on the same spell list as the substituted one'.

Wizards and Archivists know all spells in their spellbook / prayerbook. So, dip 1 level of either, and enjoy access to a fantastic range of new spells.

*yawns*

I found something more powerful than a Druid/Planar Shepherd, it's called a Wizard that cast Planar Bubble and uses Wish to craft a full Ring of Three Wishes. It's not even RAW mangled like Rashemen and actually works. Yeahee me.

[zook1shoe]

Of course that's better, but that's not relating to the OP's need for it to be Druid/Planar Shepherd.

otherwise you can talk about any of the dirty tricks being better

Smart ass comment about a Wild Shape Amulet making a Planar Shepherd even more better to make up for last smart ass comment not being taken as it was meant to.
