I like a lot of that stuff. Crimson is very

ty compared to Corruption. Accessory from crimson is pretty useless, while band of starpower is at the moment essence of mages (well, magic cuffs>celestial cuffs are, but you understand what i mean) My idea is:
Band of Bloodpower: restores 20 mana upon killing an enemy
Combined with Band of Regeneration gives:
Bloodfury band: Upon killing an enemy automatically starts mana regeneration, gives 10% magic damage buff for 2 seconds after killing an enemy
now we have Mana regeneration band equivalent, lets go further
Bloodfury necklace: Bloodfury band + panic necklace
Regenerates 10% of mana and gives 10% magic damage buff and 10% movement speed buff for 2 seconds after killing an enemy
Celestial Necklace: Celestial magnet + Bloodfury necklace
Regenerates 10% of mana and gives 10% magic damage buff and 10% movement speed buff for 2 seconds after killing an enemy. Increases mana star attraction range
