Title: Add invulnerability window after captcha completion

Description:
This is a suggestion to add an additional invulnerability window after captcha completion to give players time to react.

Why is this a good idea?
I have myself personally encountered at least 2 deaths and certainly a few more near death ones due to captcha while levelling and on a 1x char too which hurts even more. I believe adding a short invulnerability window after captcha window completion should help alleviate some deaths or at least let me quickly @load to get out of danger. I believe that this should not significantly offer an advantage over other players but it does give players a short amount of time to react after luring a bunch of mobs and getting hit with captcha.

While captcha causes the char to be invulnerable during active captcha window, it doesn’t exactly help after the player completes it especially for my archmage with a 2h staff which more or less instantly died once I finish the captcha.

Case in point here - rip exp:

What risks or downsides does it have?
Might be difficult to code the behaviour or might unintentionally provide an advantage over other players within that small window.

To be honest the captcha is now starting to get annoying. Every single time I go somewhere to farm it keeps popping out. And after completing it the mobs aggro will start coming in, either causing you to die or near death.
