You know, the collector leviathan, what if, he can make water current too? using his tentacles, to make us go to him, it would make him smarter!

Just like Reaper, I want Collector to do -80 damage to Tadpole in one strike. and then if the Tadpole health is 80 or less then 80, i want an animation where he punch hole the glass, grab us out and then eat us animation. so in total 2 shot you’re done for.
If this seems harsh. To counter this, I want Collector to behave like curious creature, like when he first saw the Tadpole, he swim close to it not attack but to observe what is this. He will catch up because he is fast. If the player keeps Tadpole still, move very slow. After a minute or so Collector will leave it, assuming nothing interesting to collect. But if the player panics and starts to run in his sight, Collector gets and then he proceeds to kill you.
Plus, when grabbed, while the long animation is playing before you get eaten. Give players ability to use the knife (only if carrying) to do damage to his tentacle arms, if lucky you break free from that. Make the hit random sometime its takes 5 hit to break free, most often 4 hits, or if you lucky sometimes its happen in just 2 hits. But he grab you again in the same time, now no hit will work.
