Weapon Block

Template:SD After developing this skill, an Assassin wielding two Claw-class weapons can use her blades to deflect incoming attacks, thus giving herself a defensive edge without using a shield. (Requires two equipped Claw-class weapons.)

Stat	Value
% Chance of Blocking	min (20 + [ 45 * [ (110*slvl) / (slvl+6) ] / 100 ], 65)

• Only applies when stationary (whether idle, attacking or casting) or using Whirlwind. Blocking animation and sound do not always play when applied, particularly when applied in quick succession.
• Does not apply while Assassin is a Werebear. [1]
• Applies to missiles, melee and ranged attacks. Does not apply to the following sources of damage: [2]
  • Charging Claw Vipers and Reanimated Horde
  • Attacker Takes Damage and Attacker Takes Lightning Damage
  • Returned damage from Thorns, Iron Maiden, Iron Golem and Spirit of Barbs
  • Psychic Hammer
  • Mind Blast
  • Corpse Explosion, Death Sentry corpse explosion and Nihlathak corpse explosion
  • Radial damage from Holy Fire, Holy Freeze and Holy Shock
  • Static Field [3]
  • Telekinesis [4]
  • Shiver Armor cold damage
• Fire damage per second is blocked, but since fire damage is actually applied every frame (25 times per second), often by multiple missiles, damage is reduced rather than prevented entirely. [5]
• May also appear to be ineffective against skills releasing multiple missiles, especially those applying Poison Damage: individual clouds released by Poison Explosion or Plague Javelin may be blocked but it is extremely unlikely that all will be blocked, and it only takes a single collision to apply poison damage for its full length.
• Not applied consistently to Smite when used by a Paladin, although monsters using Smite do not always hit and can be blocked. [6]
• Neither Dexterity nor % Increased Chance of Blocking from items will increase chance of blocking.
• Block rate is the same as when equipping a shield, and Faster Block Rate applies.
