For the Assassin questions:
1): Dragon Tail works exactly as you have described. The only thing to remember is that Dragon Tail's damage is calcaulated from the physical damage received by your target, and this can be affected by various methods of damage reduction. A physical immune monster, for example, will also be immune to Dragon Tail. If you had a physical damage output of 100, but attacked a monster with 50% physical resistance, you would deal 50 physical damage total, and L1 Dragon Tail would add 25 fire damage to your attack.
2): Dragon Claw only releases charges once. The same thing applies to Dragon Talon.
3): Cloak of Shadows will disable ranged attackers exactly as Dim Vision would. The one complication here is that it only affects those monsters which were within range of the skill at the time of casting, and these monsters will be marked with a plume of smoke over their head. The darkened sky caused by Cloak of Shadows has nothing to do with the skill's actual effects.
