Posts from What is more important: luck or fighting spirit?

There's no need to argue – just choose both skills, and that's it. Besides, the game allows for it (I personally do it that way).
And you also forgot about their simultaneous effect (I remember it being like that with the High Elves: double luck + morale, then double luck again).

+1 morale/luck gives a slightly more than 4% chance of it occurring, at least that's what is written in the physics guide, and it agrees with practice. But negative morale occurs more often than it is written, about 1.5 times more often.
In general (except for Necropolis), Leadership is significantly better than Luck, both in terms of additional damage and in terms of tactical advantages. But both skills are only taken due to inevitability. For each race, there are 8 other more useful skills.

The probability of the event you described in the third game is approximately 0.000029.

Well, I'd say you're quite the optimist, or maybe a storyteller. Or are you confusing this with the topic about 5 heroes?

There's nothing to argue about here – just choose both skills. Besides, the skill slots allow for it (I personally do it this way).

Let's imagine a situation. The hero has one skill slot left, and you're offered to choose either Leadership or Luck. What would you choose?

Isn't that right? +1 morale and +1 luck – both have a 10% chance of appearing, and 2+ has a 20% chance, respectively.

4.2% for ±1; 8.3% for ±2, and 12.5% for ±3.

Well, I'd say you're quite the optimist, or perhaps a storyteller. Or are you confusing this with the topic of 5 heroes? Even with morality and luck at +3, the probability of the event you described in Heroes of Might and Magic III is approximately 0.000029.

4.2% for ±1; 8.3% for ±2 and 12.5% for ±3..

I'll take Leadership, and here's why: Luck only increases the base damage, meaning it ignores the Attack and Ranged Attack skills if the hero has them. Morale, on the other hand, doesn't ignore these skills. Also, Leadership allows for more flexible use of the additional damage gained from Morale. I'll only take Luck if the army already has +3 Morale without the Leadership skill.

Undead simply won't have a choice between Luck and Leadership. They never get the Leadership skill.

In my opinion, luck is more important because:
1. Morale is easier to boost.

If you're playing as Necropolis, but not with a Necromancer or Death Knight, then you have a very interesting tactic. :)

But what's the point of giving a hero leadership...? Necropolis can't have morale, neither negative nor positive.

That's a good argument!

What the benefit will be, we still need to figure out, but the fact that a hero playing as Necropolis might face the dilemma from the first post – that’s quite possible. :cool:

And what makes him easier to level up? :)

A Necromancer or Death Knight shouldn't get leadership as they level up! And playing as undead, for example, with a Druid or Barbarian – in my opinion, that's perverse!

1) From the very beginning, it's +1.
2) Archangels give +1.
3) There are more artifacts that increase morale than those that increase luck, and they are easier to find.
