Re: How did Kurapika tank Uvogin's Big Bang Impact?
Well, he did use In, he also distracted him to keep him from using Gyo, so he could use In on the Jail Chain and capture Ubogin succefully.
While re-reading the chapters I began thinking about Emperor's Time ability, and I think I could understand it, and I think there's a lot of confusion about it.
Emperor Time let's you use all kinds of Nen at 100% of their efficiency. It also depends on what level have you developed that particular kind of Hatsu. Which reminds me of Biscuit's training levels.
So if Kurapica got to level 6 in transformation, he will be able to fight to a level 6 transformation user. Now, if he trained to level 10 Reinforcement, in normal state, he would only be able to fight at 60% of level 10, but on Emperor's Time, he'll be evenly matched. I guess it works that way, depending on training, so normal Hatsu's rules doesn't apply...I might be confused though...
Kurapika didn't create any opening. He even said that he was able to capture Ubogin because he stopped to gloat about his power. True, his tactics confused Ubogin, but you're still not supposed to just stop and talk about how awesome you are in the middle of a HXH fight. If Ubogin continued fighting as normal, Kurapika could not have caught him.
The level system is basically a way to stop Emperor Time from being invinicible. It says your max level is limited by your natural school, so let's say both Ubogin and Kurapika can learn up to level 10 in their current mastery of aura, then Ubogin can learn level 10 Reinforcement and Kurapika can learn level 10 Materialize. The % modifier means Ubogin can only learn up to level 6 Materialize and Kurapika can only learn up to level 6 Reinforcement. Now normally, Kurapika can only use level 6 at 60%, versus Ubogin who is level 10 at 100%. Emperor Time takes him to level 6 at 100%, so he was able to guard Ubogin's attack taking relatively little (by HXH standards) damage. It cannot get him to level 10 at 100% because if it did, he should be able to guard the attack successfully without taking damage.
Now of course your overall level of mastery of aura can go up over time but we've to assume between characters of similar talents they're fixed, otherwise what's stopping a Specialize type guy from training his level to 1000, and then he gets Reinforcement level 400 at 40%, and assuming level is exactly linear increase, that's still like having Reinforcement level 160 at 100%! From the manga we can infer that training your aura level is a very time consuming process measured in years, and that progress slows down drastically as you get higher. So 'get more levels' is simply not an option at least for similar characters.
Now of course the Ants definitely start with more aura levels, so to speak. Razor and Biscuit probably has a higher starting aura level than say, Hisoka, since it's hard to imagine Hisoka guarding against either of the two character's Reinforcement-based attack without taking significant damage, even though all these characters are exactly one away from Reinforcement. Of course Biscuit is like 50 years old, and I guess Razor is at least in his 30s compared to Hisoka who is not quite 30 yet, so this is a reasonable difference.
An interesting observation is that this means Kurapika must be a similar aura level compared to the Spiders (the Spiders certainly plan for him as if he's an equal) despite him having only an year of learning at most compared to guys who must have at least 10+ years. Maybe the Spiders never bought Biscuit's best selling 'how to master Aura in 10 days" book?
