Here's what I found on the forum, @ag.
I carefully watched the video (with different filters that enhance the image), analyzed the "numbers" for damage and unit stats. What I managed to figure out is below.
Of course, I might have made some mistakes somewhere. Plus, this is the mechanics of the alpha version; the formulas can easily be changed by the release.
Damage Calculation
Now there are 2 types of damage: physical and magical.
To calculate physical damage, the "PhysicalAttack" and "PhysicalDefense" characteristics of the unit are used.
To calculate magical damage, the "MagicAttack" and "MagicDefense" characteristics of the unit are used.
Damage is calculated using the following formula:
Damage = AttackerAttack * (1 - DefenderDefense/100) * random(1-Spread; 1+Spread),
where AttackerAttack is the total attack (physical or magical) of the stack, displayed in the stack's characteristics window;
DefenderDefense is the stack's defense (physical or magical), displayed in the stack's characteristics window.
Spread is a number in the range [0; 1], which determines the damage spread; it is different for different attacks - I don't understand how it is calculated (for example, when Ghouls attack Griffins, the spread = 0.125; when Vampires attack the same Griffins - 0.066).
That is, damage is essentially the "total attack" of the stack, from which a percentage is subtracted, as indicated in the "defense" of the attacked unit; plus, a spread is applied.
The total attack of the stack is calculated using the formula:
StackAttack = UnitBaseAttack * NumberOfUnits * (1 + 0.025 * HeroAttack),
that is, the stack attack is the total attack of all units, increased by 2.5% for each point of the Hero's Attack.
UnitBaseAttack is not displayed anywhere, it seems.
Stack defense is given as a percentage, which reduces the damage received. The final stack defense is somehow calculated from the unit's base defense (not displayed anywhere) and the "hero defense" characteristic. I couldn't figure out exactly how.
I'm not sure about Magic Attack/Defense - the base damage for Liches turned out to be correct, but not for Ghosts.
The rest regarding the game mechanics:
- Critical damage is not equal to the maximum, as was said in some interview; it is higher (how it is calculated is not yet clear). In the video, Vampires attacked Griffins with a "predicted" damage of 112-128 (1 killed); when they attacked, the "cinematic camera" turned on (a sign of "crit"?) and they killed 2 Griffins (I couldn't make out the damage numbers).
- Griffins counterattack in response to enemy counterattacks (possibly a bug).
- Hero characteristics (in parentheses - the values for the hero from the video): PhysicalAttack (2), PhysicalDefense (11), MagicAttack (29), MagicDefense (24), MagicPower (10), Mana (620), Initiative (0, bonus for units?), Morale (0) and Luck (44).
- The Distance characteristic of units is, apparently, the percentage of the stack's attack that is dealt with ranged attacks: none - no ranged attack, half (skeletons) - 50% damage, full - 100% damage. For the Skeleton attacking the Griffin, it was almost the same, at least.
- Unit characteristics from the hero's army in the video
Attacks - base, other characteristics - taking into account the hero (MagicDefense = 28, PhysicalDefense = 11, Luck = 44).
It is very difficult to distinguish 3 and 5 in the video, and I might have made mistakes somewhere else.
In any case, most of the characteristics will change by the release; now you can only judge the "general direction" of the unit.
At Def Ini HP Mat MDef Luck Speed Dist
Skeleton 5 32% 30 20 - 51% 48 4 Half
Grave Ghoul 8 39% 35 36 - 58% 51 4 None
Vampire Knight 15 48% 43 74 - 59% 51 5 None
Lich - 44% 25 36 23 58% 51 4 Full
Ghost - 34% 30 24 7? 54% 51 5 None
Creature Abilities
I couldn't make out all the words from the descriptions, so I inserted "???" in such cases.
All undead creatures have 4 common abilities:
Undead: ??? to Poison, Disease, and Water spells.
Emotionless: something about the effect of morale (does it not affect the undead?).
Allegiance to Asha: something about Undead and Asha's will, nothing else is clear.
Vulnerability to Light magic: Light spells that damage the living are more powerful against Undead. Light spells that heal the living damage Undead and Demons(?).
Unique to creatures:
Skeleton:
Hollow Bones: Skeleton suffers only 30% of physical ranged damage.
Webbing Spears: The attack creates a 3x3 square zone that slows movement. The web disappears instantly(?) but the movement debuff lasts for 2 turns.
Grave Ghoul:
Dead Flesh: The Ghoul's ??? like hardened leather, making them more resistant(?) to physical damage.
Rage against to living: When attacking living targets? both damage and movement? is increased. +30% damage, +2 movement.
Lich (Elite creature):
Drain life: The energy of enemies, destroyed by the Lich, is transferred to his allies.
Vampire Knight (Elite creature):
Vampiric? Embrace: 10% of damage done by the vampires to living creatures heals the vampire stack and raises previously fallen units. Only effective damage counts (absorbed and overkill damage don't count).
Out of time: When the Vampire Knight chooses to defend, the next attack targeting it will automatically fail.
Ghost
Incorporeal: Can move through obstacles. Physical damage on the wraith is reduced by 35%.
Death Seal: In addition to ??? shadow damage, the target is flagged(?) with a 30% resurrection (healing) efficiency debuff for 3 turns.
And there is one more ability that I couldn't figure out
