as i said many times. lilys should give a 50% increase per lily on any skill you intend to use. so you can either increase single healing/damage, dots or aoe healing/damage. this would make it unique and very flexible. all you gotta do is active lilys odor and choose one of the empowered spells. Last but not least give lilys an optical update. after consuming a lily blossom fall on the ground or something...

what do we need cooldown for? its not like you hold all skills on CD all the time but use them when they are needed.
