Concentration is the second of the Paladin's three damage enhancing auras, the other two being Might and Fanaticism. Compared to Might, Concentration is superior in every way: it provides more damage per skill point invested, and gives the added bonus of making 20% of all attacks done by the Paladin and his allies to be uninterruptable.
In addition to that, Concentration also provides a half of its damage bonus to Blessed Hammers. This means that a lvl 17 Concentration aura will increase Blessed Hammer damage by 150%.
Compared to Fanaticism, Concentration has better party buffs, but lack the Attack Rating and Attack Speed increase that Fanaticism provides. Concentration is however better for a party, and for a Hammerdin.
Lore[]
Those within the sphere of influence of this skill gain the gift of clarity. A serene sense of lucidity eases the minds of those within, giving them the freedom to focus on individual tasks despite the chaos and distractions of battle. This sense of tranquility allows the Paladin and his comrades to strike calculated and devastating blows.[1]
