Shistavanens level up like "normal" characters such as Anzat, Gotal, Probot, C-3PO, Ithorians and Sakiyan. They're faster to level up than Katarns, faster still than IG-88 and R2-D2, and way faster than Spider and Terentatek because they require less XP than them.

Shistavanen's Special Power
Special power is to stun a beast for 2 turns and do 1.5x damage. But if there's no beast, then the special cannot be activated.
