Well if you're planning on just healing in catacombs pump all your points into intelligence and get heal mastery robe and weapon and charm, and put your healing charm in your accessory slot. If you want to damage in catacombs get intelligence armor and weapon, and put the damage charm in your regular slot and maybe a heal in your accessory.
If you plan on solloing, put your first 10-15 points into vitality and the rest into intelligence. Use the same build as you do for a catacombs damage dealer, except a heal charm in necessary.
PM me with any further question.
