Evaluating Intelligence

Evaluating Intelligence affects the spell damage of various Magery spells (similar to how Tactics increases damage dealt in melee/ranged combat), but only direct damage spells such as Energy Bolt, Meteor Swarm and Fireball. It does not increase the strength of healing or poison, or indirect spells that cause damage like Summon Creature. It does not increase the severity of a condition like Paralyze or Protection.

It can also be used to determine the target's overall Mana and Intelligence.

Beyond giving your spells increased damage, Evaluating Intelligence also contributes to a chance for a Critcal Hit on spell cast- dramatically increasing its damage. Once you've reached 60 in both Magery and Evaluating Intelligence, spell crits are unlocked.

With 80 Anatomy and Evaluating Intelligence, there is a chance to dodge an attack and thus prevent spell interruption, similar to the effect provided by Wrestling. This provides more interesting builds for Mages.

Spell Damage
Evaluating Intelligence is primarily used by Mages due to its increase in the effectiveness and damage of Magery spells. Upon casting a spell, the potential damage is calculated based on several factors, such as the spell being cast, its Spell Circle (or the difficulty of the spell and the expertise required to cast it successfully), and the individuals Magery skill.

There are 3 formulas which Evaluating Intelligence governs:

Direct Spell Damage Formula
Direct Spell Damage determines the overall spell damage of a harmful spell.

Positive 'Buff' Spell Formula
The Positive 'Buff' Formula determines the potency of helpful 'buff' spells.

Negative 'Buff' Spell Formula
The Negative 'Buff' Formula determines the potency of hurtful 'buff' spells.
