Omega

Omega is one of the most powerful of the greek letter spells, copying all the other spells in the wand at once for 300 mana.

Tips

 * Like Gamma and Alpha, Omega is very useful for copying valuable limited charge spells like Black Hole that aren't affected by the Unlimited Spells perk, effectively making them unlimited regardless. However, unlike the other two, this one can cast any amount of cast-limited spells at a time (for a much higher mana cost and cast delay).
 * Omega is often used as a workaround for low spells/cast wands, with its only downside being its high mana drain.
