Wandering Vagrant (Risk of Rain 2)

The Wandering Vagrant is a returning Boss in Risk of Rain 2.

Behavior
The Wandering Vagrant spawns when the teleporter is activated, gently floating, and generally not moving. Their attack pattern consists of launching a series of exploding orbs, spawning a slow-moving, homing ball of energy that detonates on impact, and releasing a high-damage nova.

All of these attacks can deal a lot of damage. The bombardment can usually be dodged as the orbs aren't too accurate. The homing attack can be destroyed by dealing damage to it, but this can hurt the player if the attack is too close.

The most dangerous attack is the nova, as it deals high damage and has to be either fled from or blocked by positioning a solid object between the player and the Vagrant. As the Vagrant is airborne, however, this can be difficult.

The nova is only used after the Vagrant has taken heavy damage, and are never used back-to-back.

It has collision, so standing atop it is possible. Indeed, this is a viable strategy, as it can't hit the player with either projectile attack as they are launched from beneath the mantle. The only attack that can (and will) hit players standing on the Vagrant is the nova.

Trivia

 * In the game's title screen, multiple Vagrants can be seen flying far in the sky.
