A Rogue I'm planning to play through Honor Among Thieves and the Prophet series. As the Prophet series require a good and somewhat intelligent character this Rogue is designed as something of an investigator, due to its chaotic nature probably a thief recruited as a secret agent who's not afraid to stab someone in the back.
A Ranger / Shadowdancer played in the the Shadows of Undrentide (SoU) plus Hordes of the Underdark (HotU) campaigns. This ranger is an archer using stealth to evade enemies or gain some distance if enemies get too close.
A Paladin / Champion of Torm used to play the Neverwinter Nights Official Campaign (OC) and Shadows of Undrentide (SoU) plus Hordes of the Underdark (HotU). This paladin is nothing less than a divine tank.
