I suggest to you to wait some other day and look for other comments, you can ask to OldTrees in the guru thread meanwhile.
Without the flooding limitation, this skill seems to be real overpowered, with a
can istant kill a creature with a flooding combo. Seems too much easy to do. That's why I prefered first version.
In addiction, should be cloaked when underwater, with flooding it's again a simply condition to satisy.
In conclusion: I really prefer first version :\
