Hello. I enjoy FhH2 very much.
I'm sorry for my poor English.
Unrestricted Burning Blood
Moroi never die when he cast Burning Blood. (Text: 75% die)
And Moroi with Loyalty and Burning Blood effects never become barbarian.
So Morois with Loyalty can cast Burning Blood wiht no penalty. Very strong.
Unrestricted collateral damage (Pyre Zombie)
Pyre Zombie's explosion have no limit of collateral damage.
Effects to not living units
Courage, Gift Vampirism, Loyalty, Valor are only used to living targets.
But their effects remains when an effected unit upgrads to no-living unit.
ex1 Archmages cast Lichdom to transform Liches.
ex2 Warriors are drown to Drowns.
ex3 Vampires upgrade to Eidolons.
ex4 Vampire Lords cast Lichdom. (Rare case)
Immortal Great Peoples
With Blood of the Phoenix, great peoples can get Immortal promotion.
They can used twice, so only three Great Prophets is need to build Altar of the Luonnotar.
Life 3 is useless for Doviello
Luchiurp, Grigori and Doveillo can not resurrect Hero.
Barnaxus can be resurrected by Picese of Barnaxus, Grigori have many heroes, so this is not penalty for them.
But Doveillo have nothing.... and can not build the Shrine of Champion.
Lucian would be resurrected ?
4 Krakens and 4 Treants (Druid)
Disciple summon limit is not restricted by the number of casters, but the number of unit type of caster.
Zealot can upgrade to Druid without limit of level 6.
Whichever other Druid's religion, Druid of Octopus Overlords can cast Kraken as much as the number of Druid.
Druid of Leaves can do same.
So, one Druid can cast Kraken(or Treants) 4 times.
Unrestricted Kraken and Treant (Grigori Medic)
When a Grigori Medic obtains Religion of Octopus Overlords, he can cast Kraken as much as number of Girgori Medics.
So, if Grigori has 20 Grigori Medics, one Grigori Medic can cast 20 Krakens.
Grigori's Armada Krakens easily destroy enemy fleets. (Krakens can get experiences from combat !)
Same as above, one Grigori Medic of Leaves can cast Treant as much as number of Girgori Medics.
Hero Lich Legion
Hemah and Gibbon Goetia can get Death 3 easily.
After they had become Lich, they will not abandon when the civilization change religion.
Corlindale and Govannon can make 4 Hero Liches and Shrine of the Champion.
1. Get Death 3 and become Lich.
2. Get Life 3 and cast Resurrection.
2nd (or more) Lich can get Twincast. (summon Wraith, or other rank 3 spells)
If your are Amurites, 5th Govanon get rank1 spells.
Govanon with Death 1 can make Disciple Heroes to Lich to use rank 3 disciple spells and avoid other civilizations use them.
I think a unit with Hero promotion should be restricted to become Lich.
Unrestricted Peace
Corlindale cast Peace and die.
Corlindale (Lich) with life 3 can resurrect Corlindale.
Get cities, and cast Peace. Get cities, and cast Peace.
With Torlent, Elohim is warmonger to controll wars. Ethne the Black.
Unrestricted Impersonate Leader (Gibbon Goetia)
Gibbon with BlackMirror and Enchant 3 promotion can cast Impersonate Leader multiple times.
1. Gibbon cast Enchant Spellstaff.
2. Gibbon cast Mirror.
3. Mirror of Gibbon cast Spellstaff.
4. So Mirror of Gibbon can cast Impersonate Leader, and die.
5. But Gibbon (original) is still alive.
Svaltalfar with Gibbon and Alazkan can destroy many civilizations.
Golden age by Black Mirror
Mirror of great people can trigger golden age.
I think Black Mirror should be an ability of Alazkan, not item. Item can get by other civilizations.
And I think Impersonate Leader and Peace should be world spell or only be used once per game.
