The idea of melee attacks being blocked has completely changed and it doesn't happen by default any more.
This skill allows people not dual wielding that have either a 2H weapon or a "worn as shield" slot item to block strikes. Mobs can block
with bare hands but builders must configure mobs to use that skill.
If a strike were to hit you, it will check against the block chance. If you block, you take no damage but equipment can still be damaged. Unlike parry, you CAN block mob bare-handed attacks.
You can RIPOSTE off of blocked shots, even against mob bare-handed attacks.
For 2-handers, you have a base chance to block of 4% plus 1% for every 10 points of strength over 50.
For 1-hander+shield builds:
Your base chance to block is 24%
You gain 1% for every 10 points of strength over 50.
You lose 6% for every secondary attack item you have.
Your block chance extends to guns where you can block entire shots.
Your block chance extends to direct damage spells where you can reduce damage by 50%.
For both archetypes, if you're not awake or motionless (paralyzed, stunned), you won't be able to block. Being less-than-standing can also reduce your chance to block attacks, spells and guns/bows.
