Curiousity and continually looking for equipment that is slightly better than my party is wearing at the moment, that's what takes me to the next dungeon or mountain. Great, I found a +5 hitpoint ring I can give to my druid, so she can give here old +3 hitpoint ring to one of the sorcerors, and then I can sell a +2 intelligence ring!And of course I HAVE to take out ALL the bad monsters in the most spectacular ways - that's why I'm very fond of the elemental magics. Striking that pack of vicious Hydras with meteor showers and star bursts, before they even spotted me ;-)
Not yet however, at the moment it's just cold beams and arrows on the approaching head hunters...
Once I tried a non-violence game with clerics and feeble minds. It didn't work - the cobras that stood behind others weren't affected and when they continued to attack me, the already pacified ones joined in also - and it wasn't fun so I quit that one.
