Thanks for the Votes! (Vision Card)

most flat numbers are essentially percentages. just like how 10 def pretty much means 10% damage mitigation

eater/killer abilities adds to a skill's multiplier instead

You go to summon there's a thanks for the votes summon you have to do all steps for 75 shards (I thinks 75 maybe less)

Try going to Mog Shop and select the anniversary (B) exchange. You can get however much you need to awaken, provided that you have the event coins to do so. Otherwise, you'll need to summon for them. Personally, I needed 15 shards to complete the task and had 100 event coins available to exchange.

I've encountered Yuna, Tidus & Zazan during PVP..

Enemy has Zazan w/ 7k HP and can 1 hit my Rain. He also dealt 5.4k damage to my 120MONT

Not limited, and in the normal pool
