[Adept]

A nonmagic nataraja has to be one of the best supercombatant pretenders.

Four ice-swords will give him +4 attack and an awesome +16 defence. And don't forget 4 devastating sword attacks /round.

As the skills of your smiths grow you can change to four swords of swiftness for 8 attacks / round and the same bonuses. Add boots of trampling and other boosters and you have a true Destroyer of Worlds.
