Stray

Strays are an upcoming variation of skeletons that only appear in certain biomes.

Spawning
80% of Skeletons spawned in ice plains, ice mountains, and ice spikes biomes having a view of the sky will be Strays. Spiders spawned in said biomes have a chance of spawning with a Stray riding it.

Behavior
Strays behave much the same as normal skeletons do. However, they shoot tipped arrows that inflict slowness for 30 seconds on any target that it hits. Despite shooting slowness arrows, Strays are not immune to slowness.

Drops
In addition to normal skeleton drops, strays have a 50% chance to drop a tipped arrow of Slowness. With Looting, this chance increases to $2×level+1/2×level+2$.
