Help me with Druid's 18th level Feat

[S_Jerusalem]

Hey all! I have a Druid that just reached 18th, in an Age of Worms campaign. Stumped on my L18 feat, my current list is:

Extend Spell
Companion Spellbond
Law Devotion
Persistent Spell
Natural Spell
Quicken Spell
Fiery Burst

I am playing a variant that has turning attempts, which is why I have Law Dev, but I am avoiding DMM.

I'm currently considering Easy Metamagic (-1 level MM cost) for either Quicken or Persist. Other possibilities include Sculpt Spell, Energize Spell (150% DAM to Undead, 50% to living, MM+1), or maybe Extraordinary Spell Aim. Sudden Max is a possibility to go nuts with a high level summons, beefed by Ring of Mighty Summons.

I cannot use non-Greyhawk setting feats. Thanks in advance for the help!

Sculp's always good.

Don't overlook Leadership. 

[S_Jerusalem]

I would really consider Leadership were we not in the Writhing Tabernacle, with likely no opportunity to pick up a Cohort for another full level or two.

No opportunity to save someone being horrifically tortured who, gratefully, joins your band of dude?

+1 for Ocular Spell

No Dragon Wildshape?
It's in Draconomicon and, depending on available Sources(for example: MM II for Gem Dragons) can get you all the (Ex) and (Su) abilities of a small to medium dragon.
Besides a moderatly powerful Breath Weapon, the main benefits are utility. It is great, if you take it at Level 12, don't know how much use you get out of it at higher levels.

Since I have, I believe, 4x 9lvl spells/day, DWS probably is mediocre at best.

I was thinking Ocular Spell, but can't quite come up with a great list of Druid spells to use it with. Any thoughts/suggestions on that? I know that it is a powerful feat, so it may be worthwhile with only 2-3 good candidates to apply it to, I just only have experience w/ it as a Sorc/Wiz where it is obviously badass!

I'd go with easy metamagic if you don't want to do DMM.  Also, DMM Quicken at this level is probably balanced.
