Best Spells?

[Nerfix]

Yeah, Seeking Arrow is a powerful and a very frustrating spell.

As for best spells...just some, out of the top off my head.

Blade Wind (Earth 3, Evoc 4) - Certainly a winner in early age, this is a truly monstrous spell in fine-tuned squads of Basalt Kings or Agarthan Oracles with Earth Boots, Summon Earthpower and then Bladewind...of course it is far, far less useful against armoured targets but with so many things running around pretty much buck naked in the Early Era this spell is stupendously effective.

Mirror Image (Air 1, Alt 2) A nice buff spell that scales well with power. This one, AFAIK, also protects you again AoE spells! Be careful that enemies can luck out and hit through the Mirror Image.

Body Ethereal (Astral 1, um, forgot the level) Quite possibly the best protection spell before you run into magic weapons. You can also protect others with it too, albeit at a short range.

Rhuax Pact (Earth 1 Fire 1 Conj 3, Agartha Only) - An amazing little ritual, this one summons 5 magma children for 2 fire gems. Since fire gems can be easily made into gold we get 5 Magma Children for 30 gold. And that is amazingly cheap for what you get. Of course fire immune and resistant creatures nullify Magma Children and they are somewhat weak to missiles but against regular infantry and even some tougher creatures they are utterly amazing, blowtorching their way through twice larger forces.
