3.0
-AI is aware of the extra -3 save penalty on undead when selecting a target for Exorcise.
-AI is aware of the extra -2 save penalty on normal units when selecting a target for Annihilate.
-Fixed bug : AI considered Spell Locked units valid for Exorcise and Banish again, it got broken in a previous update
-Fixed bug : Banish and Exorcise randomly wasn't cast when it was supposed to work (original 1.31 bug)
-New AI BUY decision procedure : AI now prefers to buy Sage's Guild, Alchemist's Guild, Fighter's Guild, Amplifying Tower, Wizards's Guild, if they can pay 2x their buying cost, Sawmill always, everything else if they can afford 50x the buy cost OR have over 10k gold.
-AI with the Alchemist retort now prefers to maintain a 20% gold 80% mana ratio instead of 50-50 in mid and late game. This should allow them to allocate more on casting skill and research, and only the minimum needed on mana production. If the 80% would exceed 24000 mana, the ratio is adjusted to make sure no resource is wasted by the 30k caps.
-In the optional portrait files, the Sage hero's unit sprites have been redrawn to match the character name and portrait.
-New AI power distribution procedure.
-Now considers the Chaneller, Sage Master, Archmage, Mana Focusing, Alchemy retorts.
-Now considers Sorcery Conjuction
-Now considers the research of Spell of Mastery – able to prioritize or avoid researching it, or do neither as the overall game state demands.
-Now can set amounts in increments of 1% instead of 10%.
-Rush research early Gargoyles, Giant Spiders, Lycanthropy
-All previously added improvements still included or further improved.
-New AI combat spell selection procedure!
This should make adding improvements here significantly easier, as new code can directly be comiled and inserted. The following new features are already included :
; Earth to Mud - additional priority to use on turn 1
; Call Centaurs - additional priority if no enemy unit can reach and enemy has no or low ranged capacity
; Web - additional priority is the target would be a flying unit at a gate
; Web - additional priority now scaled based on amount of own units capable of attacking fliers instead of a flat +15
; Web - additional priority if the target is a hero increased
; Web - additional priority if the target is alone, especially if caster is a unit not a wizard
; Web - Additional priority when own Flying Fortress is in effect and target is a melee unit that flies and cannot teleport
; Single target Direct damage spells - priority increases for each point of expected damage dealt above 3 - simulates the attack 10 times and uses the average
; Single target Direct damage spells - priority not increased for overkill damage
; Single target Direct damage spells - priority boost doubled for heroes - if overkill damage is expected, additional major priority boost : never a waste of MP to get rid of a hero!
; Single target Direct damage spells - Chaos Conjuction no longer adds priority : instead the spell strength is raised appropriately for the damage calculation -> Priority raises as much as the damage dealt!
; Resistance based spells - priority reduction if success rate is below 30%
; Resistance based spells - priority boost for each point of missing resistance on target above the first 3
; Resistance based instant kill spells - additional major priority boost based on success rate in % if target is a hero
; Resistance based instant kill spells - additional priority boost if target is an expensive unit
; Resistance based instant kill spells - additional priority boost if target is a hero
; Resistance based instant kill spells - priority reduction for missing figures
; Resistance based instant kill spells - additional priority if target has the Regeneration ability, as all of these are irrecoverable damage
; Resistance based instant kill spells - priority group is D if chance to hit is low, is type A if high instead of always A
; Resistance based "take control" spells - above changes also apply to them
; Resistance based instant kill spells - cheaper spells (Exorcise, Petrify) have higher priority if chance of success is identical
; Iron Skin - Priority slightly reduced if enemy plays Chaos or Sorcery (too many effects pierce armor)
; Regeneration - additional priority boost if expected to win battle and targeting a hero
; Regeneration - do not use at all unless expecting to win (battle evaluation result, AI has at least medium advantage)
; Entangle - additional priority for each unit having movement 2 or less that will become immobile.
; AEther Sparks - if target has MP, additional priority proportional to amount of MP.
; Spells that check ranged attack strengths - These now consider the To Hit and Ranged To Hit of units. (such as invisibility, guardian wind, etc)
; Confusion - additional priority boost based on success rate in % if target is a hero
; Flight - No additional priority give if the AI has enough units capable of attacking fliers (flying, thrown, breath, ranged, gaze)
; Flight - Additional priority is given if the unit at the gate is flying
; Mass Invisibility - If enemy has no illusion immune units the spell can be cast even if they have no ranged units. (enemy not seeing the units is a big tactical advantage, plus the -1 To Hit penalty is not bad)
; Wall of Fire - Enemy units immune to fire or magic are not counted for priority
; Wall of Fire - Enemy units with 7+ armor or less than 3 figures are not counted for priority
; Immolation - additional priority for each enemy units that has multiple figures, no immunity and no high armor
; Flame Strike - enemy units immune to fire or magic are not counted for priority
; Flame Strike - enemy units that have 21+ armor are not counted, the damage would be too insignificant
; Flame Strike - if fewer than 2 enemy units are counted, spell cannot be cast, unless the unit is invisible and no units can see it
; Disintegrate - additional priority if target has the Regeneration ability
; Disintegrate - additional priority boost if target is an expensive unit
; Mind Storm - additional priority boost if target is an expensive unit (reduced resistance can unlock instant kill spells, reduced defense makes it vulnerable to attacks)
; Warp Reality - Will not be used if own chaos units do not exceed enemy chaos units by 3.
; Exorcise, Holy Word - The additional -3 save penalty on undead is considered in the new resistance based priority boost
; Annihilate - The additional -2 save penalty on normal units is considered in the new resistance based priority boost
; Healing, Healing Charge - The value of the target is now calculated as though it had no damage - as damaged units have proportionally lower value, resulting in the AI not healing units that are too wounded, even if they are valuable.
; Healing - Do not use if total damage on the target is enough but total RECOVERABLE damage is not.
; Raise Dead - Heroes with extremely high stats will no longer be overlooked due to priority overflow (78+ total stats)
; Mass Healing - No longer considers units having less than 3 damage, or the damage is irrecoverable
; Mass Healing - New priority formula, type C+10*(units healed) instead of 5+10*(units healed-1) untyped.
; Mass Healing - If only one target is found, spell won't be used. Normal healing is superior and the AI will almost always know it if they have MH.
; Holy Word, Massacre - Priority now depends on sum of percentage success chance on each affected unit instead of the total number of figures affected
; Holy Word, Massacre - if the above sum is below 50% the spell is not used
; Holy Word, Massacre - Priority is weighted by the percentage of remaining figures in the units instead of the number of them
; Holy Word - If unit is enchanted by Spell Lock, it is considered immune to the spell
; Supreme Light - now belongs to type C in addition to the calculated priority from units affected
; Weakness - additional priority if target has low attack strength and success chance is above 50%
; Weakness - Will not be used if target has a magical ranged attak
; Cloak of Fear - Will not be used if enemy army contains too much ranged units (too much as in, more than one or two really weak archers)

; Cloak of Fear - Will not be used if the above isn't at least 2 high chances than low chances.
; Life Drain, Syphon Life - priority increases for each point of expected damage dealt

; Darkness - now considers enemy Death units and own Life units as well
; Mana Leak - additional priority for each enemy unit with a magical ranged attack or mana pool
; Mana Leak - priority to be used against city walls lowered - AI units will usually go and attack so this will rarely drag human units from behind the walls.
; Mana Leak - can now be used as an anti-invisibility tactic even if otherwise invalid - to drain MP from the hiding wizard. Priority boosted in this case.
; Terror - now counts as a type C spell
; Terror - now grants priority for each enemy unit (for the -1 HIT), but additional priority for units that have a 40% or higher chance to skip turns
; Wrack - Priority now boosted by % chance of success on each affected figure instead of merely the number of figures
; Wrack - Will not be used unless there are at least 36 figures affected at a 10% chance, or equivalent = expected damage 3.6/turn
; Wrack - Above treshold is significantly lower if all enemies are invisible and no illusion immunity is available
