What is your party composition?

[Ilium]

Human Rgr3/Ftr4/Duskblade2/OOBI 1 (and no XP penalty!)
Dwarf Ftr 10
Human Rog1/"Cleric" 9 (actually a homebrew divine caster)
Human Monk7/Tattooed Monk 3
Human Rog 3/Ftr 4/Dread Commando 3
NPC: Aasimar Pal1/Wiz7/Spellsword1

So a big group with pretty much all the bases covered, but weak on trap-handling and without 5th-level spells for a 10th-level party.

 

[brehobit]

Human warlock
Human warlock
Human wu-jen
Human paladin (archer)

The scary part is that they are pretty effective. (2nd level only though)

 

[SCMrks]

My group is all 5th level now in a Forgotten Realms campaign:

Human Paladin
Human Swashbuckler
Dwarf Fighter
Elf Ranger
Elf Fighter/Rogue
Elf Fighter/Wizard (going for Arcane Archer)
Dwarf Cleric
Elf Druid
Human Warlock/Sorcerer (Fey Heritage)
Elf Warmage

 

[Dracomeander]

Our Eberron group consists of the following:

Warforged Fighter 21 / Juggernaut 5 with a Warforged Scout Rogue 6 / Artificer 14 cohort
Half-Orc Barbarian 25 / Legendary Dreadnaught 1
Human Cleric 19 / Rogue 2 / Dragonmark Heir 5
Human Wizard 26
Half-Silver Dragon Weretiger Druid 18 / Ranger 2 (don't ask me I'm just the Psion)
Half-Silver Dragon Kalashtar Psion 10 / Elocator 13

The Half-Dragons were a plot point when we freed a silver dragon spirit from a Dragon Orb. Also, the wizard didn't join us until we were already into epic levels.

Our FR group consists of the following:

Halfling Paladin 20
Half-Earth Elemental Dwarf Fighter 18
Half-Red Dragon Human Barbarian 19
Snirfneblin Rogue 10 / Dungeon Delver 10
Half-Fire Elemental Sorcerer 17 / Fighter 1
Human Cleric 10 / Morninglord of Lathander 10

This campaign is using the option to buy off level adjustment from the UA.

The characters of our Ptolus campaign at this point:

She does not have access to the most secure parts of the Sadar Mansion yet.

[sjmiller]

Let's see, the characters in the 3.25 (3e with additions) campaign I am running are:
Raythe, Litorian, Revised Ranger (from Monte Cook) 3/Litorian Racial Levels 3
Aereva Moonwhisper, Loresong Faen, Sorcerer 6
Phomer Gorsebramble, Loresong Faen, Sorcerer 6
Jolinar, Human, Cleric of Kord 6
The Berringer de'Grackle, Gray Elf, Rogue 4/Wizard 2
Keldeth, High Elf, Fighter 6
Lirial Fingannin, High Elf, Bard 2 (she's new and wanted to start from the bottom)
Quinn, High Elf, Monk 6

Before they left due to personal conflicts, we also had:
K'rain, Human, Paladin 3
Nightingale, High Elf, Bard 3

They left when the majority of the party was 3rd level.

 

[Voadam]

I play in a solo

Ranger 1/Wiz 5/Harper Mage variant 1/Eldritch Knight 8

When he was with a group of 5 PCs he was probably mechanically the weakest but he does great as a solo.

I took over running the rest of the group which consists of

Fighter 1, Paladin 6, Chained Templar homebrew prc 9
Fighter 4, Cleric 12
Fighter 16 (archer build)
Wizard 5, Rogue 3, Arcane Trickster 7, Archmage 1
Druid 5, Master of Many Forms 5, Warshaper 5, LA+1 elemental water homebrew template

They do everything well niche-wise except for social interactions, for which they are missing my PC's contribution (moderate social skills from harper mage class and maxed sense motive from EK)

 

[Cedric]

Current party is only three people:
Man at Arms
Squire
Member of the Guild of Arcane Lore

No ‘levels’ or ‘classes’ or hit points, because I’m not playing DnD

Ars Magica?
