Bug Report

I applied Eternal Stella to my Tetra pick in the Smithing Table, and it worked as intended(Became unbreakable).

Observed Behaviour
After honing it, it started to take damage during use as before. No longer unbreakable.
Also didn't list the text "Unbreakable" like other enchants.

I then tested with vanilla enchantment books on another Tetra pick.
I honed it when it became available, and the vanilla enchantment stayed.

The Tetra Workbench doesn't seem to accept the Eternal Stella as an enchantment either.

Expected Behaviour
For the tool to remain unbreakable.
(also listing the word "Unbreakable" or "Indestructible" in the tool description.)

Minimal setup needed to reproduce
-Tetra + Dependencies
-Forbidden and Arcanus

• Forge version: 1.16.4 - forge-35.1.29

• Tetra version: tetra-1.16.4-3.5.3.jar

• Tetra configuration: Default

• Forbidden and Arcanus version : forbidden_arcanus-1.16.4-1.0.0.jar

• Forbidden and Arcanus configuration: Default

• Other mods:
  Valhesia 3 - 1.16.4 Modpack
  Steps to reproduce

1. Get Tetra tool via workbench.
2. Apply Eternal Stella in Smithing Table, making tool indestructible.
3. Use until honing becomes available and hone it.
4. Use to break a single block to see green durability bar appear.
   ...
5. Weep, because it took forever to find a Stellerite Piece.
6. Go in creative to get another Eternal Stella.

I think that's an issue on Tetra's side. Could you open an issue on their tracker if there isn't already one?
