Of course, the sword of the angelic alliance.
It suits everyone, even the dead are affected by prayer.
And of the real ones (which are given as a bonus at the beginning of the game)
the necklace of speed.
And the book of earth is also not bad...
Posts from Artifacts in Heroes III.
Category 1 (treasure) - I like the ring of the dragon (which gives +1 attack/defense)
Category 2 (secondary artifact) - gloves/amulet of speed (depending on the situation)
Category 3 (main artifact) - cloak of speed/sword +6 attack/boots of speed/handcuffs/charm of courage/bag of 1000 gold
Category 4 (relic) - wizard's hat (if there are no spells, otherwise it's not needed)/angel wings/book of earth and air
Among common items – the Sphere of Inhibition (or something like that) and the Shackles of War.
+1, but it's not very effective against elementals and undead. :) And if it's a Grail artifact, it would be more objective to simply call it the king of artifacts, it's a very useful item, don't you think?
Among artifacts – the Horn of Plenty is unrivaled.
Among regular artifacts – the Sphere of Inhibition (or something like that) and the Shackles of War.
But in my opinion, the Golden Bow, for example, and the Sphere of Inhibition are good. =)) (I'm not talking about the Grail and the Blade because I consider them to be as powerful as artifacts, so after them, the game becomes pointless, IMHO).
(I'm not talking about the Grail and the Blade because I consider them to be comparable in power; after obtaining them, the game becomes pointless, in my opinion.)
