The Spark of the Phoenix is one of the five reducing death penalty blessings available in Tibia. See Blessings for prices and death penalty reduce data.
To obtain the Spark of the Phoenix, you must visit Kawill and Pydar (in that order). They are located in the lower levels of Kazordoon. Kawill is southwest of the temple, down one floor at the stairs before the Molten Rock Fellowship. Pydar is north of the temple. Even though you must visit two NPCs to get the entire blessing, you only pay once, with Pydar.
To reach Pydar, for the Blessing, there are several Fire Fields in the path. The character needs to run through the Fire and take damage, or use Destroy Field Runes. If running, it is better to move as quickly as possible since the damage from several fields is not cumulative.
This blessing can also be obtained by using a Phoenix Charm.
