Sylph Skills

[R29016091]

Already assuming the answer to my question is no, but I'll ask anyways. Below is my 4 star Blue Gaia. I have filled all 5 slots for non-passive skills. What I want to do is buy Thunder Strike (230% +1580 dgm + 3 rounds of 30% slow) with the aim of replacing lol Thundering Strike (165+120 dmg).

Obviously I can't buy a free slot, so am I stuck just rolling the dice and hope the new skill replaces the one I want it to and risk it replacing something else? There's no way I can specify what I want replaced is there?

you need to be like this to learn, and is new skill are all random, you cant choice what to replace not even in china patch as now. i was lucky to get all skill i want in 1 try.

First of all you won't be able to learn Thunder Strike skill because those 4 skills at the bottom can be learnt only when you refine your gaia into Hercules.
Also i think currently there's no way to specify which skill should be replaced when learning a new one (i'm not 100% guaranteed for it)
