Discussion of level 1 monsters.

Regarding the power of first-level creatures, it seems like a somewhat awkward question. Perhaps it would be more accurate to talk about the usefulness of first-level creatures – specifically, from this perspective, the most advantageous and in-demand creatures are those that provide early-game mobility – such as sprites for Haven and imps for Necropolis (40 movement points). Other factions can't boast this (especially Haven and Sylvan, although at least they have stables). However, centaurs for Stronghold also look quite good, with 30 movement points. Otherwise, first-level creatures are only useful for about a week or 10 days at most – they are then used to capture the first mines...
Something like that.
