Well, let me share my opinion. Inferno is my favorite Castle. I often choose it in duels.
This Castle doesn't have as many "powerful" heroes as some others, but it does have some decent ones, which is already a plus. Personally, I choose: Peer (Logistics) - probably the best hero, Nimue (Offense) - a good hero, but there's a drawback: on the third level, they might offer either Basic Navigation or Basic Scouting (which is very unpleasant :mad:), Marius (Demons) - and you can "breed" a lot of demons :-) Ignathus (Imps) - on early stages and small maps, he's simply invaluable; many Imps and +1 speed help quite a bit... Zydar is a good mage.
The units here are my favorites. Archdevils :smile51: - speed and retaliatory strike, as well as -1 to the opponent's luck (not morale, as some say; morale applies to Dragons), which is a small but nice bonus, but they are unfortunately inferior to Archangels :smile36:, Behemoths :smile19:, and Titans... However, they can be used in battles against slow monsters with great success!
Efreeti - the fastest level 6 creatures, fire immunity (which means the ability to use Armageddon, for example, in battles against neutrals: attack with Efreeti and cast Armageddon), and fire shield is also a great asset!
Pit Lords - their speed isn't impressive, but they hit hard + they summon demons, which is very useful.
Demons - they are taken not for their quality, but for their quantity.
Cerberi - speed and retaliatory strike, they can be used in some places, but they often sit in the dungeon...
Gog - the only ranged attackers, but unfortunately, they are weak...
Imps - fast, under Ignathus's command, they look very good, especially with the Grail (because the possibility of placing a Grail hasn't been canceled...).
And in general, as someone rightly pointed out, the level 1-3 units should become Demons!
Magic. Inferno is dominated by fire magic! Someone already wrote that there are many useful spells in fire magic!
1) Curse - a great spell, especially nice to cast when the opponent casts Bless :-)
2) Protection from Fire - quite good, especially if followed by Armageddon :-)
3) Blindness - in addition to its natural function, expert Blindness gives a retaliatory strike and can also be used to prevent the enemy from escaping.
4) Berserk - no comments, especially good against those who don't have expert water!
5) Frenzy - a rather specific spell... but it hits hard :-)
6) Armageddon - everything is clear here, it's good with the Sphere.
7) Sacrifice - my favorite! It revives very effectively! It's simply indispensable in a difficult, equal, or final battle.
8*) Town Portal - in the version of HEROES 3 TE, Town Portal has moved to fire magic, well, that's better for us :-)
Special buildings: Town Portal - can be useful if there is no Town Portal spell or if there are many Castles.
Order of Fire - it won't be лишним (superfluous) either.
This town is also good because the creature dwellings don't require crystals, which is also a plus when playing on "King" difficulty.
It should also be noted that when playing on a random map, the town is quite unpredictable; the territory can be either very bad or very good...
So, as you can see from the description, Inferno has quite a few advantages, and it's definitely worth playing as! Good luck!
I'm waiting for criticism! Sincerely, Dirty_Player.
P.S.: Sorry for the spelling!
