[Bengt]

Note that it was only a Singing Spear that could be thrown in 4th edition. In the 6th to 8th editions it has been strictly melee.

Where does the life drain come from? It has never had any ability like that in 40k. The curse could damage Yriel directly in 4th and makes him easier to damage in the later editions. It has never been all that powerful either, capable of killing mooks but pretty mediocre for killing characters/monsters.
