Kongol

Kongol is originally a boss that appears at Hoax and then Kazas. He is once again encountered at the Home of Gigantos and from here on out he remains in the party. His brutal strength and gigantic size are a deadly combination.

Unlike in other games, the fact that all healing is percentage based turns aside the threat that characters vulnerable to damage pose to the availability of healing, somewhat. In other words, the fact that Kongol has double the HP of other characters does not mean that healers have to heal him more to get him to full or half. So his more-than-half magic resist is actually less of a handicap than his more-than-double health pool is a bonus.

The same may be true of his damage output, or not: he is strong, but he is slow. However, one thing is certain: having Kongol in the party is as much about saving healer's turns so they can do damage, or replacing healers in the party so damage dealers can be added, as it is about getting turns doing damage. The Pandemonium Repeat Item is a natural for Kongol, taking physical damage on his peerless armor and superlative health pool and away from squishies.
