Hey, if you are a high level ek, i think it's worth, coz 2x mana leech keeps your mana high and you can hunt solo in dangerous places with the only worry to heal yourself. The mana will always be high and you can "exori", "exori min", "exori gran", without the risk of running out of mana. You have only to attack and heal with supreme pots.. Hope i've I've been usefull useful and good hunt :).
