2. There's no need for upgrades here; they already have good strength and defense, plus a special ability.
3. Spirits and ghosts seem to be the same, but it's better to use regular upgrades because they have a higher chance of hitting.
4. Higher-tier units are definitely better. Do they counter Vampires? It's not in the spirit of a hero to rely on weaker units, even if they're slightly better, but at least they won't be countered!
5. At the beginning, after Archangels, you can divide them into two equal squads.
6. At the beginning, I'll take Messengers, and later, Banshees, because if you use their special ability on a group of Banshees, it will be more effective than using the Messengers' special ability, even though the Messengers have higher stats.
7. Bone Dragons - Only they are better in terms of stats; Astral Dragons only have Sorrow, and even that is weak, so they are less effective than Bone Dragons.
