They call me Cable, because I have lots of channels, but most of them s*%k.

[Eponine Lokrien Savet]

I am contemplating an odd build:

Level 1 Oracle of Life w/ Channel (Dual Cursed)
Level 2 Necromancy School Wizard with Command Undead
Level 3 Cleric of Ranalc with Daze variant Channel (Travel and Nobility domains)
Level 4+ Back to Oracle

Race: Gnome
Stats:

6 Str (-2 Points); 12 Dex (2 Points); 12 Con (0 Points); 14 Int (5 Points); 12 Wis (12 Points); 19 Cha (13 points).

Traits:
Magical Knack (Oracle) and Sacred Conduit (+1 DC of Channels)

Level 1: Improved Channel - 5 1d6 channels / day, DC = 10 + 4 (cha) +2 (Improved Channel) + 1 (Sacred Conduit) = 17
Level 2: Spell Focus (Conjuration) - Wizard Bonus Channel to Command Undead DC 17, 5/day
Level 3: Selective Channel - Channel to Daze DC 17 5/day
Level 4: +1 Cha, 5/day channel Negative to Command Undead, 6/day channel Positive to heal 1d6, 8/day Channel Negative to Daze.
Level 5: Channel Ray - Misfortune Hex
Level 6:
Level 7: Versatile Channel
Level 8: +1 Cha
Level 9: Quick Channel
Level 10:
Level 11: Divine interference
Level 12: +1 Cha

+2 Int Ioun Stone, +2 Wis Ioun Stone, and +6 Cha Headband.
+4 Dex/Con belt
Circlet of Persuasion

Cha at 12 should be 28 ish, for +9

Daze DC will be 21
Command Undead DC will likewise be 21
Heal will be 5d6 with DC of 26

Channels will be DC 23 (Daze), 23 (Command), and 28 (heal) via Channel Ray.

I will be able to channel 12/Day (Daze) 6/Day (Command) And 12/Day (Heal) or half that quickened.

Update: Are there any items that improve Channel DC, or other Feats, Traits, or . . . Anything? Drugs?

Drugs^
Dunno if its exactly what your looking for but it sure is fun :)

Further update:
Swap Quick Channel for Fateful Channel, and you can have up to . . .

12+12+6=30 channels/day each capable of granting all allies a huge boon!

Aasimar with 'Channel force' is a good way to go when specializing in channeling.

Looks cool, dotting for stealing

You might want to move Versatile Channel to 3rd, and enter Envoy of Balance at 5th. At 7th (Envoy 2) it will stack with your previous channels (although it's not clear if it only adds to your channel power from cleric?), and at 9th, you can channel both positive and negative at the same time. You need to figure out how to get a third level spell too, which might push it out a few more levels.

Personally, I don't think the necromancer level is worth it, and I don't think versatile channel lifts the "only for using these feats" restriction.

You can't do Fateful Channel(Pharasma worshiper) and be a Cleric of Ranalc, so you'll need to pick one.

Life Shaman(Witch Doctor) will also give you a bunch more channels (4+2*Cha, or 22 at your 12th level target.) Cleric 5/Shaman1/Envoy 6 would be a lot of powerful dazing+healing channels.

I've got an Aasimar Shaman build in this vein for PFS. Fateful Channel is handy, but reminding people to roll twice gets a little clunky. :)

spirit guide oracle gets life shaman channel at 3rd dont they?

[Markov Spiked Chain]

Spirit Guide doesn't get the Spirit Ability until 7th. That's another option for OP, but loses out on Dual Cursed Oracle.
