""Anyone who seeks to pass, this point is destined to die.""

- - Trismagia

An ancient and powerful demon known as Trismagia is the oracle of the demon world. It is fought by both Dante and Lucia in Devil May Cry 2, however, it is unclear which of them encountered it last.

Description
Trismagia looks like an enormous head with three faces and three sets of eyes. Each head has the ability to use one of the elements of Ice, Fire, and Electricity. He has the ability to split into three heads which can attack one at a time, or recombine them for a powerful strike using all three elements.

Strategy
To defeat Trismagia, wait for it to split in three, then begin shooting all heads. These heads are each one of a color, and each one has its color and elements: To defeat Trismagia, you must discover which head is the true one, by shooting them from where you stand. Keep switching your targets, until one of the heads feels the pain and loses HP. When the heads get too close, get away quickly, to avoid their attacks. Their final attack is to regroup into one again, and shoot a mega blast from all mouths. Don't be tricked so easily, because this attack does not take the whole area (be careful when its life is low, because from here on, the Mega Blast does, sometimes, take the whole area). So look for a safe spot in the arena to escape. Then repeat the whole strategy to defeat it.
 * The Blue, happy face attacks with lightning balls from afar, and thunder rings when it's close.
 * The White, sad face attacks with ice balls or/and ice pillars from afar, and an icy cloud at close range.
 * The Red, angry face attacks with fireballs from afar, and explosions at close range.

An alternate strategy is to "hit and run" when Trismagia splits into 3, and keep doing so until he reunites again into a sole head, as even if he attacks with all the 3 elements at once in this phase, it is to note that he also takes more damage while united than when separated. DT-firearms combo will damage Trismagia for considerably more damage.
