Rhapsody is a support hero who excels at dishing out and bolstering Magic Damage. Her Staccato and Disco Inferno abilities combo for great damage output if used correctly, and her Arcane Hymn enhances all nearby allies' Magic abilities. Rhapsody's ultimate, if used properly, can determine the outcome of a game by shielding all nearby allies from both Magic and Physical damage.
Rhapsody is a ranged Intelligence support hero who packs healing, Magic Damage, a powerful stun, and a channeled ultimate which renders nearby allies impervious to Magic and Physical damage.
Staccato: Deals 50/60/70/80 Magic Damage and a 1 second stun to target, then applies 1/2/3/4 charges to Staccato. Staccato can be used further, each time consuming a charge and dealing 50 Magic Damage and a .25 second stun.
Disco Inferno: Lays down a dance floor of groovetacular moves. Allies standing still in the dance floor will heal 10/20/30/40 Health per second, while enemies standing still in the dance floor suffer 20/40/60/80 Magic Damage per second. The effect lingers for .5 seconds after the target begins to move.
Arcane Hymn: Nearby allies' spells are enhanced by an aura and gain 6/12/18/24 Magic Damage Lifesteal and 1/2/3/4 Magic Armor Penetration.
Protective Melody: Channels for up to 4/5/6 seconds. While channeling, grants nearby allies in a 500 radius 1000 Armor and Magic Armor.
Staccato and Disco Inferno combo perfectly together. Use the pulses on Staccato to cause enemies to stop for a bit, then do it again after .5 seconds (when the linger on Disco Inferno wears out) to re-apply.
Staccato can be used to interrupt attack and cast animations if timed correctly. It can give you a huge advantage in early exchanges.
To take advantage of Arcane Hymn, your allies must be in the aura while damage is being done. Make sure the Thunderbringer is standing near you when he ultimates!
Protective Melody is best used in clutch reactionary situations. Don't use it pre-emptively unless you're absolutely sure they're going to initiate! It has a low duration, and is HUGE if used right as it will waste enemy attacks and spell casts, as well as divert attention to you.
