Penumbra, Netzach, Demigod, and Beauty Seal, plus occasional Chaos and Beauty blessings if someone blesses Ilithoid with them. I think that's pretty much it. Ironwill up, performance on, and beauty ring will help with ego beyond that, plus anything in psymet to boost ego, if there is such a beast.

And Lion sphere if the sun is Conjunct, Sextile, Semisextile, or Trine to Lion.

Considering getting a race change. What are the various good races for a Harbinger?

Faeling is always the first on the list, being Glomdoring and all. Plus they have good intelligence/charisma even at base, and that should help in Music stuff. Human gets a mention, too, for the evolution thing. Furrikin, elfen, too, if you want that fun and not be too crippled!

Stat wise the answer is always Failing. Especially because you're Harb. Especially because Glom likes to have at least 4 domoth blessings on it at a time.

I'm already demi, so not seeing the appeal of human that much. Faeling has good offensive stats, but they seem rather weak defensively. I've rather grown to like the tankiness of kephera, so I'm wondering if there is any option that is similar to keph in terms of decent defence and good bardic stats, but is less....bugly.

For dwarf, does brewmeister have to be the actively selected skillflex tradeskill to get the stat changes?

Humans are more then an XP bonus. They get stat bonuses so they're a decent choice anywhere really.

And I'd imagine, yes, you would need brewmeister to be your active skill. Sounds like a bug if don't.

Plus a throne.

Also, not strictly a cha boost but beasts can cure ego.

What does the affliction 'broken skull' do?

Humans don't seem like a good choice to me where Harbingers are concerned. By level 95, their Charisma grows by a whopping +1, from 12 to 13. Comparing a level 95 human (bard evolution) to a level 95 Shadowsinger Faeling:

Shadowsinger Faeling
+4 Dexterity
+4 Charisma
Level 2 Health/Mana regen (in forests)
level 3 faster balance
level 3 faster elixir balance
level 1 faster herb balance
native use of FLY

Human
+5 Constitution
+7 Strength
+9 Size
level 2 faster XP gain

Both FLY and extra XP gain are ultimately marginal advantages, but Strength and Size are both Harbinger dump stats, and there's no pressing need to have them particularly high. In my opinion, all of the faster balances, +4 Dexterity, and +4 Charisma more than outweigh +5 Constitution and two other unneeded increases.

I've thought about this myself (reincarnating at a later date, I mean), and I may do so eventually, but nothing really compares to Shadowsinger Faeling when it comes to bards, and also influencing, even if you don't do that.

Human stat growth is based upon archetype though. Doesn't Bards get an unique human statgrowth?

My charisma as a demi human bard with the usual bard buffs, beauty blessing, and a throne is 19. Shadowsingers have a wonderful charisma, especially as demigods, but to be honest their constitution is... terrible. Sure, you have regeneration if in a Wyrden environment and a sip/herb bonus, but against big bursts of damage it's still rough.

I'm certainly not saying Shadowsingers are bad- in fact, I like them, but that constitution is just awful.

Human bards get the same as guardians/wiccans. At 95, it's 13 Str, 14 Dex, 14 Con, 16 Int, 13 Cha.

Geez. They should probably be rewriting that then. More dex than cha? All three archetypes have access to ego-based skills.

However, all three archetypes benefit from high dexterity, as it controls parry/stance effectiveness.

Which is why a lot of non-warriors shrink to size 1 these days - they don't use str, but do use dex.

Also, fairly sure all bard damage is jointly determined by int and cha, so that +4 cha isn't as impressive in that regard.

None of em use strength though. Moving that strength to cha would be nifty in my regards.

Shieldstun!

One skill versus three skillsets.

Yeah...

I've never seen 'broken skull' and it's not in the Wiki. Is it something new? If you mean 'fractured skull' the Wiki has it as "One third of commands fail to take effect."

It's a shofangi aff, but I'm at a loss as to what it does. (Might this be the same aff, by a different name?)

Pretty sure it's fractured skull. Same difference.
