Natch on pigeonholing. Most characters are working with masterwork stuff as far as I know. I do requisition equipment, but there are lots of higher-level paladins that get priority, and requisitioning is the only reason I've got full plate. Potions, as consumables, are in short supply. :/
You know how these holy wars can be. Since it's a solo game and the DM doesn't want to just kill me off, my biggest struggle is just trying to actually contribute. There's only so much I can do -- supermount won't go up stairs. Lots of running, jumping, climbing, squeezing, battles in tight corners. Secret passages and such.
Really, if it weren't for the regular poisonings, rogue would've been a better choice. :/
edit: Well, except I'd have fewer hit points, worse weapons & armor, and no spells at all (see early note about low-to-no magic).
