Warrior, Mage, or Paladin?

Back then, there wasn't much to the Paladin in terms of lore :(. There's nothing particularly special about him, so it's better to play as a Mage.

Choosing a hero class based on a unique ability that you'll get at some unspecified level isn't very rational. It's much more important to consider the distribution of runes, which you receive, and the growth of skills.
In this regard, the Paladin has one important advantage: his Spirit runes are in demand in almost all skills.

By the way, regarding "Resurrection." I looked at the manual for LoR and discovered that there is no such ability there :eek:!

However, Resurrection is placed in the spellbook at the start. Considering how difficult it is to find this spell, it's a good bonus.
