Blood Edge

By rotating your blood at high speed, you can increase it's strength and lethality by making a weapon out of it. You can spend up to your Charisma modifier in blood points to create any kind of non-magical melee weapon as a free action, although they count as magical for the purposes of overcoming resistances and have a duration of 1 minute. For every two blood points used the weapon gains one additional damage tier (d10->d12->2d8). This feat counts as an Extension Technique for the purposes of class features. This also means you can’t create melee cursed tools this way.
