Yeah, I don't invest heavily into magic so first aid is important. Bandage are cheaper that life shards, but aren't found in dungeon loot. One character that I load up with mage classes, one with holy classes, but mostly combat classes. Don't usually have difficulty soloing hard dungeons after a while. One thing I did at first was maximize charm factor on my MC no matter what my other plans were for the character since it increases the money and rep from guild quests. I don't do it so much any more since the factors are now important for many classes and maximized factors give unique bonuses.
