Editing Pit Fiend and Pit Lord (section)

=== Demon herding ===
[[Summon_demons#Strategy – Demon Herding|Demon herding]] (also called demon farming) is a strategy that can be used for Inferno. The basic idea is, that the player deliberately sacrifices [[Imp]]s and [[Gog]]s in combat in order to summon them back as demons. This is based on the fact that imps and gogs have lower attack to defense ratings than demons, and therefore the demon's hit points are theoretically more valuable (do note that [[Magogs]] have a powerful ranged ability, however). You can also herd demons from cheap low-level troops from other [[town]]s. Additionally, [[Clone|cloning]] hero's pit lords will grant an extra number of demon summonings. By using the Clone spell or having multiple Pit Lord stacks, it is possible to resurrect the same Demon stack several times during a single battle. 

Note that [[Cursed Ground]] prevents Pit Lords from raising Demons.

==== Calculation ====
The count of resurrected is determined by:

{{Math|min(floor(min([dead_count]*[dead_single_health], [pit_lord_count]*50)/35), [dead_count])}}

In order to use the full potential of resurrection, [dead_single_health] shouldn't exceed the health of demon (35). If the stack consisted from imps, optimal count of units is 12.5 times count of pit lords; if the stack contained gogs, optimal count of creatures is ~3.8 times count of pit lords (provided no health increasing artifact is in place).
