The Star Veil is a Hardmodeaccessory that combines the functions of the Star Cloak and the Cross Necklace. The falling stars will pass through all blocks until reaching the player's altitude, at which point they continue falling until hitting solid blocks. It also doubles the duration of the invincibility a player is afforded after taking damage, from 2/3 of a second (0.67 s) to 4/3 seconds (1.33 s).
The Star Cloak's, Mana Cloak's, Bee Cloak's and Star Veil's falling star effects do not stack with each other. The quantity and damage of falling stars from the effect will not be affected by having multiple equipped.
The Star Veil provides the same effect as Cross Necklace, and their effects do not stack.
