The Triplets

The Triplets are a harder version of The Twins that spawn during the Time Invasion. The Triplets are three separate flying entities connected by tendrils, each with its own attack pattern and life count. Each must be killed in order to defeat the boss. Like Skeletron Mech and Eater of Life, the later the wave The Triplets is killed in, the more likely it is to drop items

Attacks
Retinator has a yellow iris and fires yellow eye beams simler to.

Spewstan has a blue iris and fires balls of Demonic Flame.

Plutisnam has a purple iris and fires demon scythes.

Each alternate between their signature attacks and a charging melee attack, much like The Twins. Retinator's charge dash is faster and covers a bit more distance than Spewstan's charge dash, but Plutisnam's charge dash is slow but does the most damage.

Each eye has a second phase. Retinator transforms at 18000HP, Spewstan transforms at 19000HP and Plutisnam transforms at 17000HP.

Retinator becomes a mechanical eye with a laser turret in its pupil. It fires more rapidly and with higher damage, and fires in quick barrages. The barrages become more intense the less damage Retinator has taken.

Spewstan becomes a mechanical mouth. It chases the player, dashing with greater speed and range, and periodically spews streams of Demonic Flames from its mouth in a manner similar to the Flamethrower. The flames can inflict the Demonic Inferno debuff and deal very high damage.

Plutisnam becomes a Buzz Saw. it fires Demonic Tridents instead of Demon scythes and fires them faster the lower health it has. The dash can inflict the broken armor debuff which can lead to the other attacks dealing a lot more damage.

Tips
Concentrate on killing one eye first. Getting them all to their second phase at the same time makes the fight significantly more difficult.

If you have The Crimson in your world, use something that inflicts the Ichor (debuff) to significantly reduce the Triplets' defense.

It is suggested to use a ranged approach to help avoid the Melee attacks.

A long flat surface with Frostspark Boots equipped is suggested for easy dodging of attacks. Combined with wings, you are able to soar through the air dodging attacks that would (in other circumstances) eventually catch up to you.

The Star Veil/Cross Necklace are also a good thing to have around in case the Triplets happen to get in close combat with you.
