Living weapon (When this Equipment enters the battlefield, create a 0/0 black Germ creature token, then attach this to it.)
Equipped creature gets +1/+1.
Whenever equipped creature deals combat damage to a player, that player loses half their life, rounded up.
Scytheclaw’s triggered ability triggers and resolves after combat damage is dealt. For example, if the Germ token deals 1 combat damage to a player with 10 life, combat damage will reduce that player’s life total to 9. Then Scytheclaw’s ability will cause the player to lose 5 life, leaving the player at 4.
Like other Equipment, each Equipment with living weapon has an equip cost. You can pay this cost to attach an Equipment to another creature you control. Once the Germ token is no longer equipped, it will be put into your graveyard and subsequently cease to exist, unless another effect raises its toughness above 0.
