In putting together the Hero Kids Brecken Vale Gazetteer, I (finally) correctly organised the adventures into tiers of play.
In the Gazetteer, these are arranged geographically, beginning with the Adventures in Rivenshore, then Skritteland, then adventures Across the Vale.
The Adventures in Rivenshore tier are introductory adventures and will be adjusted to have Easy difficulty.
- Basement O’ Rats
- Fire in Rivenshore
- Tomb of the Lost King
- Darkness Neath Rivenshore
Adventures in Skritteland are slightly more challenging and will be adjusted to have Moderate difficulty:
- Twilight Watchtower
- Curse of the Shadow Walkers
- Mines of Martek
- Maze of the Minotaur
Beyond those adventures, the rest will be Hard difficulty.
- Wizard’s Tower
- The Lost Village
- Glade of the Unicorn
- Yuletide Journey
- Escape from the Ghost Pirates
- Reign of the Dragon
Which begs the question, what does it mean for an adventure to be Easy, Moderate, or Hard.
Until now, the difficulty of Hero Kids adventures has been a factor of their duration (the number of encounters) and the challenge posed by the enemies in each encounter.
However, the difficulty of each combat encounter is difficult to calculate, due to the multitude of factors that goes into it:
- Number of heroes (and which heroes are used)
- Enemy array for each hero
- Arrangement of heroes and enemies on the encounter map
- Hero equipment or advancement.
Those of you who've played any Dungeons & Dragons, will know that there's no easy or reliable way of calculating the strength of a monster, or the strength of a party of adventurers. And it would be foolish to think that Hero Kids is simple enough to afford a simple calculation.
But Hero Kids is simple enough to estimate encounter difficulty.
To estimate the difficulty of an encounter, we need to establish a baseline. For this, I propose that the baseline is derived from a single hero, basically factoring in that heroes abilities, armor, and health boxes (but not their Special Action and Bonus Ability).
Luckily, all heroes use the same rules to calculate their abilities (strength, dexterity, and intelligence), armor, and health. Heroes have 4 dice to assign to their abilities and armor and they have 3 health. The 4 dice arranged between abilities and armor reflect a hero's power, and the 3 heath reflects their longevity. Together, their power and longevity reflect their overall power.
This gives us a baseline of 12 power (4 times 3) for each hero.
For heroes that use ranged or magic, which cost extra dice to assign, I'm going to assume that their longer ranged attacks (and other abilities) are balanced out by their lower dice of ability dice. So all heroes have the same 12 power.
Enemies, comparatively, do not follow preset rules for their creation, so their power varies a lot. But we can use the same rules to estimate their relative power:
For these enemies, we have:
- Bat: 3 abilities x 1 health = 3 power
- Pirate Archer: 4 abilities x 2 health = 8 power
- Giant Rat: 1 abilities x 1 health = 2 power
- Skeleton Warrior: 4 abilities x 2 health = 8 power
Comparatively, a 'boss' creature is more comparable to a normal hero:
This King Rat is a boss creature, and is the same power as a single hero:
- King Rat: 4 abilities x 3 health = 12 power
Now that we have a baseline for a creature's power, we can estimate encounter difficulty.
For this, I'm using the following (rough) calculations for the difficulty of each encounter:
- Easy: 6 power per hero
- Moderate: 8 power per hero
- Hard: 10 power per hero
There are several caveats to this estimate.
First, the bosses clearly outmatch single heroes. For this, we will rely on the heroes' health potions to give them enough advantage to survive climactic battles.
Second, magic and ranged abilities cost 2 dice, but only give 1 dice for those attacks. We'll assume that these heroes are roughly the same power as baseline 4 dice ability heroes.
Third, when there are 3 or 4 heroes, their abilities reinforce each other (Teamwork, split attacks, etc), significantly increasing their collective power. In this case, some increase in the power of enemies can be accommodated.
Let's take a look at a Moderate encounter. As you recall, this encounter should have 8 power for each hero.
Based on these monsters, the combat has the following difficulty calculations:
- 1 hero: 6 power (6 power per hero)
- 2 heroes: 18 power (9 power per hero)
- 3 heroes: 24 power (8 power per hero)
- 4 heroes: 36 power (9 power per hero)
As you can see, the exact difficulty varies for each hero due to the granularity of the underlying monsters. But even with that variation, this encounter generally adheres to the 8 power per hero difficulty expected of a Moderate difficulty adventure.
So there you have it. Is this workable in practice? What's your experience been with individual encounter difficulty? Will this help? Is it close to 'correct'?
This difficulty calculation revision will be incorporated into all of the Hero Kids adventures over the next few months in the lead up to:
