Decimation

Decimation is a high-level Inferno spell available to only those who choose Inferno as their primary specialization. Decimation is a very powerful, single-target attack with a high mana cost and long cast time, though can become an instant cast for half the mana cost if the caster casts three successful Incinerate spells beforehand within 15 seconds of each other. The instant-cast Decimation will not occur if one of the three Incinerates are dodged or countered.
