I need help, im trying to capture any Sylvesti but they keep running away.
I only managed to capture one and that was my very first (with the quest)
after that 0 .. is it just bad luck or am I doing something wrong?

Hi there, you aren't doing anything wrong...they do run away. What traps are you trying to use and what rarity of Sylesti are you trying to capture?

im usually trying to capture uncomon and ive used the traps used for comon and uncomon but also the ones for the rares..
i guess i just have bad luck

Yeah, there really is a swing to successful capture. I can say that because I have some of the worst luck actually catching things, and I often go through butt loads of traps trying to catch pets only to have them run away (used 7 last night on one that ran away, and that's even with the reduced chance to flee after a failed trap). But the catch rate has a minimum cap of 20% to catch with a maximum of 60%, from what I've been told, so there is a pretty decent percentage chance to fail.
