To be honest, I didn't know if I reported this in SUGGESTIONS or BUGS... But here we go.
When using the "Unstable Mixture" skill, while the enemy (Shadow) is invisible, The "POT" animation automatically becomes invisible before you even touch the target.
Why does this happen? Something planned from the Devs to maintain some kind of balance?
Anyway, I suggest:
If this is a BUG: Fix the visual effect and leave the skill in sight of the alchemist.
If that's on purpose: At least they could leave it in plain sight before they even touch the target.
I appreciate the devs' attention and look forward to the response and, if possible, an explanation about.
