Which level of magic do you use the most (Heroes of Might and Magic III)?

Mostly levels 1-2. And I prefer:
1) Mass slow, haste, curse, shield, stone skin, bless, summon ship (on large maps)...
2) Lightning, ice bolt, blindness.
3) Clone, teleport.
4) Berserk, chain lightning, meteor shower, town portal.
5) Explosion, fly, dimension door.
