This song will return 50% of experience points lost upon death, effectively making it a party-wide Reraise I.
A level 75 with a regular Goddess's Hymnus one will lose 1,200 XP, where as using an Angel Lyre, they will lose only 1,000 XP.
Using an Angel Lyre also increases the duration of the Goddess's Hymnus by approximately 20 seconds.
This also restores 50% of Maximum Weakened HP when the player reraises.
The spell Reraise will take effect over Hymnus if a player has both active.
The reraise effect granted will wear off if the player switches zones whilst K.O.'d (e.g. being ejected from Assault)
@Crusadex: Goddess's is correct, as it is singular possessive and not plural possessive. Goddess' would imply the Hymnus belongs to more than one goddess.
