Jetshift/Viyilblud

Viyilblud is a pre-Hardmode boss in Jetshift that is fought in either biome of the world's evil.

Summoning
Viyilblud does not spawn on its own and is only summoned with a Corrupted Shard, which is currently dropped from both vanilla evil biome bosses. It cannot be crafted.

Behavior
Viyilblud chases after the player(s) at a slow speed when summoned, but will transition into a ramming stage where it will build up speed and dash vigorously. After this, it will fire Ichor streams, Cursed Flames and world-evil-amalgamated lasers. It will indefinitely loop this attack pattern until it dies, with an increased rate at lower HP values.

When Viyilblud dies, it's spikes will spin around rapidly for a short period of time. Shortly after, it will explode and drop loot.

Tips

 * Stay away from Viyilblud so that it is almost off-screen. This way, you can jump over his fastest dash attacks.
 * Staying above Viyilblud when it fires Ichor helps to avoid having your defense reduced.
 * When Viyilblud does it's Cursed Flame attack, it will attempt to hover above the player. Keep this in mind if you have a staircase or some sort of automated transportation in your arena.

Trivia

 * Viyilblud's theme is Korupted Lend, which is composed by Shadow Figure.
 * This boss replaces a scrapped boss from an old version of the mod, known as "Collin, Master of Evil".
