The Influx Waver is a Hardmode, post-Golembroadsword. It fires a sword projectile in a straight line towards the cursor as it is swung. After the projectile successfully makes contact with an enemy or another hostile projectile, it will disappear, but can return up to two more times to attack a nearby enemy, or the same enemy.
The Influx Waver's projectile has the following properties:
It travels at about 55mph and has a maximum range of 5500 tiles. It appears to fluctuate in size and becomes much smaller as it gains distance.
After hitting an enemy or another projectile, it teleports to three nearby enemies, prioritizing the original target. It does not track teleporting enemies like the Necromancer, nor does it target critters.
As with all projectiles, it slows down significantly in honey. However, if it hits an enemy in the honey, the returning projectiles travel at normal speed.
Some fast enemies and bosses are fast enough to move out of the way of the secondary slashes, drastically lowering the Influx Waver's DPS. This is especially noticeable against the Empress of Light and the second phase of Moon Lord.
The sword projectile's teleportation makes the Influx Waver a versatile weapon, suitable for both high-health targets and crowd control.
While it deals more damage than the Terra Blade, it is not a direct upgrade. The Terra Blade has a slightly faster speed and more knockback, and pierces through targets, and unlike the Influx Waver, does not rely on automatic targeting. However, the Influx Waver is superior when fighting one target.
