Skin of the Redwoods:

Does this do anything besides improve the AC on bark skin? If not, is there much point since druids don't get much use out of AC?

Ecological Conservator:

Is this only available as an imm given reward?

Metalshaper / Topical Tracer:

Am I correct in thinking that Topical Tracer completely subsumes the need for Metalshaper? i.e. if you're going to take Topical Tracer then Metalshaper becomes useless?

Haven't played a druid in awhile, but for the second two questions, you could probably discuss prereq with a guildmaster. It's likely you MUST take metalshaper before you can learn topical tracer. As for ecological conservator, if you can't ever learn it...then yeah, will have to be imm-given. Otherwise, may just have requirements you haven't met yet.

Thanks.

One more while you're here...

What herb set corresponds to a waning moon?

~

Awesome. Thanks!

I'm going to go for broke then...

Natural herbs. Dio's FAQ says that, among other things, they make your COW do its special moves more often.

Does having more natural herb sets when you call a COW make it more likely to get a higher-level one?

Does having more natural herb sets make your COW hit harder in melee, or is that offensive? Or is COW melee damage not affected by herbs at all?
