Synergy questions/abilities

Stagedright

1)What does Hela's synergy do to Loki exactly?
2) Why does Moon Knight become Unblockable or why does it say that at the beginning of a fight with Taskmaster synergy? what is unblockable?
3)Black bolt-with Medusa his provocation can be permanent, i have seen many other BB's with no Medusa and still have permanent provocation, how does this work?
4) Punisher 2099- sp1 why when hit does he lose charge? is it just a lack in the description?
5) Nightcrawler (and others)- "evade all attacks while dodging back" wh does that mean exactly? what defines "dodging back" if i hold it to switch modes, I get hit
I know i have more but will have to post them later

1. Normally loki deals the extra damage from the L2 if he has more HP than the opponent, but with Hela, Lokis HP always counts more thab the opponets health as long as the opponent is cursed and you can curse the opponent with L3.
2. Dont know the answer, dont have taskmaster to try out that, but it says this in Champion spotlight
"Moon Knight – Termination Contract – Unique Synergy

Taskmaster: Gains a 30% chance to Evade, against his current Exploit Weakness target.
Moon Knight: All of Moon Knight’s Moon Phase Abilities gains a flat +10% chance to trigger."

And as for the unblockable it is what it says, you cant block it.

3. A duped/awakened (has his signature ability) BB (black bolt) gains those permanent cruelty/fury stack when attacked and he only gets temporary while he attacks and hits you, but with Medusa synergy you gain those permanent ones when you attack against somebody with BB
4. Not shure about this either.
5. Dodging back means that when you swipe the screen and "dash back" normally you would need dexterity mastery to evade attack this way but NC (nightcrawler) is one of the few champs that doesnt need dexteritu mastery to be able to evade attack while swiping back.

Hope this helps
