It runs under GNU/Linux, so it must be pretty awesome. On my third time though Hordes of the Underdark, again as a cleric. That must be the most overpowered class in nwn. Based my third pass loosely on a cleric arcane archer build, but without the archer part.
Keeping in mind HotU only takes you through to about level 27, I adjusted accordingly. I love cleric spells, so I decided to go mostly full cleric with a level of bard. Specifically, clerics come with all the buffing spells, minus cat’s grace, greater magic weapon, darkfire, divine favor, divine power, word of faith, heal, harm, implosion, unholy aurora, storm of vengeance, and gate. (What’s not to love about a summoned Balor?)
Why bard? It’s a tumble class, like rogue and monk. Moreover, like rogue, bard has use magic device as a class skill. Finally, like the fighter classes, bard has discipline as a class skill.
The stats to 27 end up like (CBC is pretty awesome, but doesn’t work so well under OpenOffice.org):
STR 13 DEX 10 CON 10 WIS 16 (20) INT 14 CHA 13 (16) (feat: Greater Charisma +1)
Bearing in mind the absurd quantity of magical equipment in HotU, my plan was to capitalize on the divine might feat, allowing me to bash away at stuff. Naturally, I can already harm stuff to death, but what fun is that?
Including ridiculous equipment, the stats further improve.
STR 25 (+12 equipment) DEX 13 (+3 equipment) CON 10 WIS 26 (+6 equipment) INT 14 CHA 25 (+9 equipment)
Using umd to wear boots of the sunsoul +5 (+3 DEX, +5 dodge AC) and talisman of pure evil (+3 CHA, +3 WIS) is priceless. Gaining 4 AC from 20 ranks of tumble is pretty sweet too.
Naturally I’d like to further extol the virtues of nwn cleric, but I’ve spent all that time playing instead. Moreover, after 10 years it’s doubtful anyone still cares.
