Editing Pit Fiend and Pit Lord (section)

== Special Ability: Demon Summoning ==
While Pit Fiends do not have any special abilities, Pit Lords are able to summon [[Demon]]s by resurrecting allied dead creature stacks. Each Pit Lord can summon up to 50 [[health]] points worth of Demons. Because Demons have 35 hit points, this means that 7 Pit Lords can summon exactly 10 Demons. However, the total health of demons summoned this way cannot exceed the total health of the dead stack nor can the number of demons exceed the number of creatures in the dead stack. In other words, the dead stack must have had at least 35 hit points in order for summoning to work. A stack of one [[Pikeman]] cannot be resurrected while a stack of four will summon one demon. The full table can be seen [[Summon demons#Demoning table|here]].

It should be noted that [[non-living]] cannot be converted to Demons. Additionally, health increasing artifacts ([[Ring of Life]], [[Ring of Vitality]], [[Vial of Lifeblood]] and [[Elixir of Life]]) are counted in the calculations dead creature stack's total health.  Opposite, if a stack dies under effect of [[poison]] or [[aging]] its total HP value is reduced. Summoning takes up the pit lord's turn.

=== 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).
