-Rockshell: The shaman gets surrounded with a massive spiked rockshell which makes him immune to dmg while active, and heal the caster OR reflects any damage back for its duration, but makes him unable to move or cast
-Frozen Barrier: The ground around the caster gets frozen and becomes slippery. Enemies get their movement, casting and attack speed reduced while on the frozen area, and have a chance to slip and fall down, silencing and disarming them for up to 3 seconds
-Storm Sphere: The caster gets charged with the power of lightning, unloading it for nature damage whenever the caster hits his target with melee or spell attack.
-Fire Wall ( :P ): The caster is surrounded with a burning ring of fire ( :P again), damaging everything it touches for fire damage during its duration (WC II spell revival) (i know, bad references ^^ )
