Evaluating Intelligence can be used to determine the amount of Mana an opponent has left. It also affects various Magery spells, altering spell damage (similar to how Tactics increases damage dealt in standard combat) or the effectiveness/duration of a spell. It also has a role in defense when coupled with Anatomy.
Evaluating Intelligence has three uses: showing information about a target, spell damage calculation and a defensive mechanism.
Reading Mana Level
When using the skill and targeting a creature or player, it will give you the percentage of remaining mana the target has. Furthermore, an estimate of their overall intelligence is given.
Evaluating Intelligence is mostly used for its ability to increase the damage and effectiveness of Magery spells. When you cast a spell, the potential damage is calculated based on several factors, such as the spell, its circle, your ability, etc. (call this base damage). The damage then gets scaled based on the mage’s Evaluate Intelligence. At 0 Eval Int, the damage is actually reduced by 70%. At 50 Eval Int, the damage is reduced by 25%. At approximately 78 skill, Evaluate Intelligence has minimal effect, and beyond that it provides a bonus, up to a 20% bonus at Grandmaster and a 38% bonus at Legendary. See the discussion at Spell Damage Increase.
- Formula: total damage = ( base damage * ( 30 + ( 9 * Evaluating Intelligence / 10 ) ) / 100 )
When combined with Anatomy, these two skills can be used to replace Wrestling or other melee skills for defense. Anatomy and Evaluate Intelligence need to add up to 220 to have the equivalent of 120 melee defensive ability. The result of the following formula is capped at 120, so having 120 in both skills does not give a greater benefit.
- Formula: ( Evaluating Intelligence + Anatomy + 20 ) / 2
Activate the skill by macro or skill button and target a creature or player. If you don't get a gain, find a new target. If you do get a gain you can use that target and all proceeding ones again to try and gain.
Each cast of a Magery spell has a chance to gain. Training magery skill to the desired level while having Evaluate Intelligence raise passively is the preferred method. Once Magery is done training, repeatedly casting Magic Arrow is the most effective means. Wear a suit with 40% Lower Mana Cost and as much Mana Regeneration as you can. If the goal is to raise Resisting Spells while completing Evaluate Intelligence, then casting Weaken, Clumsy or Feeblemind on yourself are good choices, these will raise both skills.
Changes made with February 2010 to Mysticism made either Imbuing or Focus the secondary skills to Mysticism. Prior to that change, Evaluate Intelligence had a similar effect on Mysticism as it does on Magery.
