Stafrasters

Stafrasters are variants of Stafrushers, found in Highsteppe and the Flooded Rainforest, they are taller and wield staffs that allow them to cast magical attacks, they shoot green bolts at you that deal moderate damage, they don't track however and are easily avoided, they are also capable of using charged attacks where they remain stationary and practically immune to damage (they still take damage but it's more efficient to disrupt as they regen more than the average DPS can put out.) They are rather easy to dispatch provided that you are moving around a lot to avoid their attacks and stunning them to cancel their charged. Polymorph and Hex does work on this enemy.

Charged Attacks
Their charged attack consists of holding out their staff and bracing, while in this state they will continuously regen health and take less damage until they are either disrupted or have reached full health.
