|Location||Tower of Life, south of Ardougne|
|Examine|| He knows everything has a reason.|
Bonafido is the chief builder, as he and his team are building the Tower of Life. He and his workers have stopped work, as they believe it to be used for the wrong reasons. He is the head builder, yet he is the only builder from whom you cannot obtain builder clothes.
Unlike the other workers at the building, he cannot be pickpocketed using the Thieving skill.
- His name is a pun on the Latin phrase bona fide, which means good faith.
