Heroes 5.5 WarGame Edition - Tactical Edition.

It doesn't seem quite right; the base/upgrade for the priest is one thing, but the alternate unit has a separate name. There's a unit called "Guardians" (an upgrade for druids). Regarding the examples, I only found these with level 6 units: Frida = 6 crossbowmen + 1 paladin Erin = 6 archers + 1 shadow witch Shak = 1 paokai + 10 defilers Let's compare this to something simpler, like: Ellaina = 16 militia Daleb = 4 sulfur demons + 1 ballista Frida: The paladin is only level 6 in name (and even then, it's possible it will become a level 5 unit; there are many reasons to believe this). Its cost is 1,000. A crossbowman costs 250. The total cost = 1000 + 250*6 = 2500. Erin: The witch, unlike the original, is a level 5 unit. Its cost is 1,000. An archer costs 250. The total cost = 1000 + 250*6 = 2500. Shak: The paokai is a rather weak level 6 unit. Its cost is 1,500. A defiler costs 100. The total cost = 1500 + 10*100 = 2500. Ellaina: A militia is a level 1 unit. Its cost is 150. 16 militia cost 2400. Unlike the original, a group of ten militia is quite capable of defeating both a paladin and a wyvern. However, the strongest level 6 units (hydra, ent, than) are beyond their capabilities, but no one has such creatures in their starting army (their cost is 3,000 each). Daleb: The ballista is a level 6 unit (conditionally). Its cost is 1500. 4 demons at 225 each are included as support personnel. The total cost of the army is 2400.
