Salamander of T'kass:

The user may choose to throw the Salamander of T'kaas at an immortal individual, destroying the artifact. By doing so, the immortal must make a DC 15 Prowess check; nothing can be used to reroll this, or change what type of roll it is. If failed, they will immediately transform into a salamander for 1 session. As a Salamander, they suffer a -4 modifier on their next five mech-rp rolls. It may have other uses...
