Myriam Jahzia by normalice

Myriam can hold a max of 10 potions in her cauldron. Uses potions to enhance an ally's weapon. No cooldown.

Purple - Purple potion causes the next 4 basic attacks within 4 seconds to strike for an additional 55 spell damage in a cone of radius 10 (units: roughly half the size of a minion) behind the target. Each additional purple potion increases this damage by 15 but reduces the attack speed bonus of green potion by 1%.
Green - Green potion causes the next 4 basic attacks within 4 seconds to heal for 2% of the total damage done and increases attack speed by 20%. Each additional green potion increases the heal amount by 1%, but reduces the radius of Purple potion by 0.5.
Golden - Causes the next damaging basic ability cast to heal for 15% of the total damage done. Green potions additionally reduce the cooldown of the spell by 5% per potion, and purple potions increase the damage by 5% per potion. Each additional golden potion increases the heal amount by 10%.
