This creature is absolutely brutal in the chapter 2 environment. Miguel has a hard time getting his attack up, and this thing is immune to weapons and events. Towards the end of a campaign though, taking the hit and having it run away with elusive or chasing it down through superior movement becomes much more reliable.

One of the toughest scenarios (you know the one) in Hemlock gives you three different ways to deal with this thing. And with elusive, it should be easy enough to send it to locations that are leaving play (like on a train).

I asked to FFG and got the some answer. Questions is like below.

1. is it immune to attack ability from the weapon asset? so it means impossible to take fight action on weapon?
2. is it immune to commit attributes? like if player do basic fight ability against to Feline and commit the Overpower then is it take 2 strength from Overpower or not?
3. is it immune to damage boost cards? like if i take basic action and commit the vicious blow and success then is it take damage 1 or 2?
4. if it is not immune to vicious blow then how about like longshot that cards says deal damage (not the attack damage boost)

Answer is like below The Feline Hybrid cannot be targeted by player card effects, which means it can’t be targeted by a Fight ability or a damage-dealing ability on a player card. However, an investigator can take a basic fight action targeting the Hybrid and commit cards with effects that increase their own stats or damage output for the test. So yes, Vicious Blow can cause the investigator to deal additional damage to the Hybrid, but Long Shot cannot deal damage to the Hybrid.
