Glow Ink Sac + Glow Squid (Refinements)

What if Glow Ink Sacs could be used for combat?

1. We could craft a new potion of blindness and arrows of blindness that blind mobs or other players for two or more seconds (Could be both an advantage and an obstacle in PvP, Bedwars, Survival Games, and other multiplayer minigames). Since we already have Suspcious Stew with that effect, why not weaponize the effect for more practical use?

2. Another upgrade is a minor mechanism: Hitting a mob or the other player while holding a Glow Ink Sac in hand creates cyan light particles, illuminating the small area around the player for two or more seconds.

3. Glow Ink Sacs could also be used to significantly improve the glow range of existing light blocks, such as Sea Lanterns, Redstone Lamps, Shroomlights, and Glowstones. The upgrade would make these blocks emit additional cyan particles and alter the textures of the aforementioned blocks. The block name would be Enhanced Sea Lantern/Redstone Lamp/Shroomlight/Glowstone

The crafting recipe: Sea Lantern/Redstone Lamp/Shroomlight/Glowstone in the middle, and 8 Glow Ink Sacs around the block. 

4. Guardians won't attack Glow Squids because the Guardians' eyes are highly vulnerable to the Glow Squids' light, so the Guardians will always avoid looking at Glow Squids.

5. If Glow Squid is hit by the player, then it releases its defensive illuminative phlegm, blinding the player in a short range for two or more seconds.
