Greetings!
Hmmm...well, here is a small list of characters.
(1) Male Minotaur;
Fighter/Gladiator LVL 10/5. Having a Minotaur is just cool! I like Minotaurs, and I think they offer good combat abilities, and a different kind of role-playing experience than the standard human/dwarf/elf/halfling types. Fighter, because the class offers lots of cool feats, and at the same time provides some excellent flexibility in feat choices. The addition of Gladiator provides a sharper focus of hand-to-hand abilities, in a different approach. Add a cool-looking Gladiator's helmet to the Minotaur, and give him an enchanted trident, and a throw and return net that inflicts flaming damage. How cool is that?
(2) Male Human/Lycanthrope (Werewolf);
Barbarian/Fighter LVL 10/5. Permit the character to be Chaotic Good in alignment. This fellow can be the strange Barbarian from the northern wastes...with a few surprises when he becomes angry! Go big!--make this guy huge, with a 18 strength. Give him a Belt of Giant Strength +4. That will be for a total of +6 STR bonus. When the guy changes into werewolf form, add +2 points to STR, for (24) at +7. Add in rage, and it goes to I think 26, which is +8. With good DEX, this fellow with even a relatively modest enchanted Great Axe can be something to see, you know?
(3) Male Elf/Half-Celestial;
Aristocrat/Paladin; LVL 1/14 This character can provide good leadership abilities in a classic context. The noble elven knight will be good in social situations, have a bit of a broader skill-set than just a paladin alone, and yet, be able to stomp his enemies on the battlefield! Give him a Bastard Sword, +5 Holy Avenger, and a +2 Breastplate of Command, with say, a +2 Large Mithril Shield. Very nice, I imagine. He could be a fine character to play!
(4) Female Halfling
Rogue/Thief-Acrobat; LVL 10/5. Make her say, 3'6" and see what she can do when a spellcaster shrinks her! Alternatively, provide her with a magic item that allows her to shrink to size Tiny. The Rogue abilities are of course very cool for dungeon stuff. Be sure to give her high intelligence, so that at the 10th level Rogue Special Ability of Skill mastery can be selected. This cool ability provides 3+intelligence modifier in skills that the character can *take ten* in!--even while under stress and pressure. Yeah, this is a sweet ability! The Thief-Acrobat provides lots of neat athletic abilities that will help the little Halfling stay moving--and out of the way of getting hit, which is important for her because she doesn't have a lot of hit points. She can have a ring of Blinking, and a pair of +3 Shortswords. Watch her go to work! Provide her with a Ring of Jumping, Gloves of Swimming & Climbing, Boots of Spider Climbing, and a Cloak of Elvenkind. She should be fun!
(5) Male Dwarf
Fighter; LVL 15 This dwarf can be a source of solid combat and front-line assault. His many feats, and his dwarven abilities will always provide flexibility and consistency.
(6) Male Elf
Ranger/Rogue/Shadow Dancer; LVL 5/5/5; This elf can be an interesting character, both in the dungeon, and in the wilderness outside the dungeon. The Shadow Dancer provides good skill points (6+int/lvl) and the ability to create a shadow-creature, as well as jumping about through shadows--which are everywhere in a dungeon! The Ranger abilities provide some combat ability, as well as survival in the outdoors. The Rogue provides useful skill depth in many skills useful in the dungeon, but also rounds out any gaps in his skills from his other classes. Give him really pale white skin, raven black hair, pale ice-blue eyes. Maybe a few mysterious tattoos. provide him with +4 Mithril Chain Shirt, enchanted with Shadow, Silent, and Slick. Give him a pair of +2 Shortswords of Speed; Boots of Striding and Springing; Ring of Regeneration; Ring of Feather Falling; This elf could be a stalker type with a golden heart; or, he could be a chilling hunter, unnerving as he stalks his prey in the shadows...the rest of the party is sure to get a kick out of him!
(7) Female Elf
Druid; LVL 15; This lady can have all the advantages of a druid's broad spell selection, with a DIRE TIGER as a friend! Healer, a fire-seed thrower, befriend animals, summon natures ally, she can be so useful at every step of the way.
(8) Male Human
Aristocrat/Ranger/Fighter; LVL 1/6/8; This character can be bearded, older, some hardened veteran who drinks fine whiskey and smokes good cigars! He will be a country-noble, rough, but composed. Ranger skills are good anywhere, and will provide useful Hide and Move Silently skills that his fighter class doesn't have. The fighter-part of course, provides the awesome selection of feats that bring death to the enemy, as well as 8D10 additional Hit Points!
(9) Male Human
Wizard/Loremaster; LVL 10/5; This man can be relatively young; perhaps he is tall, say 6'4", about 220. Shoulder-length black hair, and a full beard, neatly trimmed. Wizard of course provides some awesome magical fire-power, but also information and communication abilities. Loremaster provides some cool information enhancement, which can be fun in a dungeon of ancient ruins, as well as provide an interesting character to role-play!
(10) Male Troll/Half Celestial
Cleric; LVL 15;
Be sure to provide the character with a Good alignment. Assume the character's parents--one was a Celestial minion, who visited a female Troll, who was different lets say. A divine mission was established for this character to establish a new faith for Trolls that wish to worship Good deities. This character is an important, even crucial element in this mission to change the destiny of at least a few Trolls. Along the way, the character seeks to serve a Good deity well, and help other friendly creatures. Through many travels, the character has been blessed by his divine patron. This cleric will have, besides various healing powers, and things like Flame Strike, a broad range of spells, and as a bonus, have a bit more durability than the average cleric! Just imagine--the Minotaur and the Troll could start out knowing each other as friends! The character will have all of the properties of a Troll, and those of a Half-Celestial. At 15th level, not only is this character certain to be powerful, but for role-playing reasons the character will be a challenge to play well, but he should be fun, too!
Well, I hope you like my suggestions!
Semper Fidelis,
