Calculation settings
1. Unit selection
This is where you set up the unit types you'd like to take on your march. These will be either the troops or monsters you can train, or the mercenaries you have available.

2. Army size and limits
Limits (optional)
Trained troops require leadership, mercenaries require authority, and monsters require dominance. You can find your limits on the troop selection screen, and they will vary widely based on the hero/captain you have selected, or whether you're taking your dragon.
Filling in this information allows us to detect when your selected configuration will exceed your limits. It will also enable use of the Find it for me button.

Dominance over-allocation handling

Dominance is used as a reference only. Every selected monster keeps its normal calculated stack size, even when the plan exceeds available dominance.

Base Count
This is the size of your smallest, strongest stack of normal troops (usually guardsmen). All other squads sizes will be calculated using this as a basis, optimized so that your best troops survive as long as possible.
Your current reference unit is not selected.
The Find it for me button is experimental. It will try to find the best (biggest) base count number for you based on available leadership. Let me know how it goes!
Other Inputs
Temple Level
This optional input will help you better estimate the revival cost for your army. Revival cost reduction ranges from 1.04x at Temple level 1, to 5.91x at Temple level 45.
Enemy Stacks
Specifying how many stacks the enemy is carrying will let us build a better attack assessment.
Health Bonuses
If you have any health bonuses that apply disproportionately to a given unit type, specify those here. Don't worry about being precise, but (for example) if you're using Wu then you'll want to account for the increased health of flying units.
Siege Engines (Experimental)
Siege engines (catapults and ballistae) can now be used to "tank" the first hit(s) from an epic monster, but it can take some fine-tuning to get it just right. The goal is to take advantage of the large per-unit health of siege engines, and use them as a decoy at the start of a fight so that your actual attack units are guaranteed a hit before being taken out.
Most players will have a significantly higher number of health bonuses on guardsmen, specialists, flying and mounted units, and so on. Research, talents, artifacts, and equipment add up fast.
The calculator will use an advanced formula that accounts for the difference between your highest G/S tier and your highest E tier to ballpark the overhead. You can use the slider below to tweak the number of siege engines up or down based on your results. If your siege engines are not taking the first hit, you can slide the multiplier up and try again.
The default value of 1.0 means that you will take exactly what the calculator natively estimates.
Tier Multiplier
You want lower tier units to die before higher tier ones, and one way to manage this is by increasing the size of progressively lower-tiered units.
Originally, this was done by simply doubling the unit count for every tier decrease as your stacks are being calculated. However, it was pointed out that a multiplier of 1.9 is actually better: lower tiers will retain their higher stacked HP, you can distribute more of your valuable leadership headroom to your prime tier units.
Previous versions of this calculator hard-coded a value of 2.0, so if you like the old behavior you can just fill that in and be happy. This version will default to 1.9. Feel free to use the Create Battle Plan button with various values and get an estimate of how it will perform.
