Ring of Fire

Overview
A technique that uses the users chakra to create a small spark, this glowing ember is then dropped upon the ground where it begins to rapidly grow and encircle the user in a trail of flames, rapidly growing into burning walls of fire. This technique is used to trap the victims within the area, preventing them from retreating unless they risk the torrent flames.

Special
Searing Vortex: While active, the user may pay 1 Ap and the maintain cost to increase the ring of fire into a spiraling vortex of flame. This causes additional enter/escape attempts to cost 1.5 Ap, and increases the damage from failed attempts by +15% base damage. However, this jutsu will end a full round after use (Or sooner if the 3 round limit is reached)

Normal: The user may choose to have the flames encircle themselves at no extra cost (In addition to attempting to encircle the normal two targets). The user may attempt to exit/leave the flames for 1 Ap.
