Which best add for arrow rain+snipe main?

I really need your advice since I can't afford to test all of these add gears..

Here are the list of additionals that comes in my mind and what stat benefits for me:
1. Easter Bunny Ears (Event) - Gives 6ampr+300mp
2. Gothic Hat - Cr 15
3. Grecia Mask - 6ampr+cr4+200mp but -14% dmg to light
4. Fur hat - 1k Hp + cr 10
5. Tyrant Mask -+atk and str
5. Beast collar - pretty much the same with gothic hat

Here are my gears and stat to which additional above will best suit with these:
-My stat dex>str and a bit of crt
-Using Dark knight amulet for special gear because snipe are meant to be invisible (my opinion)
-Fcrt+15 Weap and armor

I am still confuse tho on which xtal should I use for my speical gear and I can't test the difference of each xtal bcoz I don't have enough spina. Should I use Tapir or York for 1slotted, Which of the two?

 

My opinion:
Additional Equip: I think party glasses is better, because of the added stability which will help your arrow rain to land into the boss in a stable damage, and it also give 10crit which isn't bad and also 10% anticipate that is essential for battles to evasive type bosses. If your crit rate is enough, go to tyrant mask for extra cdmg and attack

York or Tapir: York coz in the end of April there will be a skill where you can summon a clone that will help you regain your mp in battles, so ampr wouldn't be a big problem anymore, maybe XD

If I use Tyrant Mask I have a total of 83%crt rate and if Party Glasses it will be 93% according to coryn calc. 83% not enough? Should I use Party glasses instead?

 

I will recommend gothic hat on this one. If you need stability just add paralysis shot(lvl 5-10 depends on you) in the combo.
