Paladin's Blessing - grants the target 50% protection from attacks; however, it loses protection from magical attacks for that night.

Useless. Forget about probabilities. It's better to have 100% protection once every 2-3 nights.

Dragon Attack - kills the selected target and, with a 50% chance, leaves no trace.

Similarly. It's better to give 2 Night Deeds: a regular assassination (every night) and a faceless one (once every 2-3 nights).
