Bottles of ink (An addition to combat)

Bottles of ink would be unstackable items obtained by right-clicking a squid with an empty bottle.

They would be projectiles, similar to xp bottles, and would have a pretty limited range. If a player or entity is hit with the projectile it bursts into squid ink particles, inflicting blindnes  and making whoever is hit to slide as if they were standing in ice for a short ammount of time.

If the bottle ends up hitting a block, it will leave a temporary puddle of ink particles that whenever stteped on would only inflict the sliding effect.

This item has no offensive capabilities by itself, rather it's a tool to disorient other players in combat in order to gain strategic advantages, wich is why i think something like this would most likely make combat more interesting.
