There is a hack/bug going around that when enabled a Blood Mages phoenix is unkillable.
What happens is when the phoenix dies, it goes into the egg forum and instantly transforms back into the phoenix, no matter how many times you kill the phoenix.
This is a big problem in FFA ( havn't came across it in other game types) where the human player will mass tower, harass with flamestrike until he has level 6 and then just use his phoenix to kill off players/buildings.
Q u o t e: id like to see a replay with this hack in the hands of someone decent. the 3or 4 widely circulated phoenix replays have some noob beating other hacknoobs even though it takes him 15 footies and 3 town portals to creep a red spot
