Daemons

All the special rules for daemons apply as described in the Warhammer rulebook. In particular note that the Bloodletter has a saving throw of 4+ due to its daemonic intangibility or daemonic aura.

Fear

As monstrous and horrifying creatures the Bloodletters cause fear, as described in the Warhammer rulebook.

Hellblade

The Hellblade drips continually with blood and is enriched with enchantment. A hit from a Hellblade causes not one wound on its victim, as most hits do, but D3 wounds (roll a D6: 1-2 = 1, 3-4 = 2, 5-6 = 3).
