Minecraft version - 1.19.2
Mod loader - Fabric
Mod version - 1.7.1
I am using the latest version available - For 1.19.2 yes

Describe the bug
Darkin Scythes Umbral Trespass ability can't be used for a few seconds after benefiting from its Omnivamp ability. If this is an intentional balancing thing then it needs to be more clear.

To Reproduce
Steps to reproduce the behavior:

1. Be in survival mode
2. Use Darkin Scythe on mobs (multiple will showcase the issue better)
3. Try to Umbral Trespass
4. Don't take any damage or wait a few seconds for Omnivamps cooldown

Expected behavior
I would expect you to be able to use Umbral Trespass when its not on cooldown. Omnivamp shouldn't be relevant to the abilities usage at all. It feels clunky and comes off as confusing. Like in league it should be used to escape multiple enemies for a moment. That is nearly impossible, if you take any amount of damage then attack Omnivamps cooldown will lock you out of that option.

This is not possible to fix from Better Combat.
The mod in question needs to rely use Java API provided by Better Combat to trigger the abilities in question.
