Ancestral Knowledge increases the shaman's total Intellect by up to 10%. It will affect both Intellect from gear and from buffs such as Arcane Intellect. The bonus stack with the intellect increase from Blessing of Kings.
The talent is useful to shamans of all three specs, since the increase to intellect will provide a small boost to spell critical strike chance, maximum mana pool, and mana gained from effects like Mana Tide Totem and Replenishment. The additional intellect gained also works with talents like Mental Dexterity, Nature's Blessing, and Unrelenting Storm, effectively making those talents up to 10% more powerful.
Past changes Edit
/ Patch 3.0.2 (14-Oct-2008): Changed from a bonus to mana pool to a bonus to Intellect. Effect increased from 1/2/3/4/5% to 2/4/6/8/10%.
