Damage vs Critical

[Person_Man]

The two methods I'm aware of of breaking the Keen rules are Barbarian Streetfighter or a Psychic Weapon Master. Mathematically speaking, each does better using a *4 weapon, rather then a weapon with a high crit range.

Also, you should know that builds focused on high crits are quite weak. Many creatures are immune to crits. Rolling high enough to trigger your crit, and then confirm your crit, is very unreliable. And even if you roll high enough and then confirm, you often "waste" a lot of damage, by reducing an enemy to -100 hit points. You just need to reduce your enemies to -10 hit points, you don't win anything by killing them beyond that point. Consistently dealing good damage is better then sporadically dealing massive damage.
