Ichaival on Bellona(arena only...for now)

Ich's a great boxing item, but I'd only consider it if I wasn't the only tank and the enemy had 2 or more AA attackers. I think it would be useful mid to late provided you were able to stay in your enemies' faces to fully stack it. By the way, we are talking about Arena, right? I wouldn't recommend it in Conquest.

That was for Kriega's sake since he tends to think everything should be focused on Conquest. ;)

Doesn't ich power stacks also proc on minions?

@Dev, yes, Ich stacks on anything.

Silent, so mostly I think it's just a situation where you still need to get to a point where you can make a build on the fly. It's okay to have some plans in place before the match even begins, but you can sort of make adjustments to a base build as soon as you see the enemy comp.

I would not suggest a long delay on getting standard MS (at least 18% e.g. Tabi). If you're insistent on getting Hastened Katana first, then IMO that should be followed immediately thereafter by further MS, whether from Masamune or Stone Cutting Sword. Not Katana 1st, and Masa 4th. Too long of a stretch there.

I will also reiterate that protections just for the sake of protections doesn't provide you with utility you can take advantage of...by going double up (Urchin + Thebes) or triple (add Mantle), you have a lot of tankiness, but no real extra function. No Void Shield which gives you and other nearby physical teammates some added pen function. No Pestilence to counter enemy healing. Etc., etc.

Ichaival would be one of those very specialized items that you can only really take advantage of if you've built enough AS to more quickly get stacks, and also specifically to counter multiple enemy basic attackers. Same goes for something like Shogun's Kusari. It's fine if you're the only basic attacker in a general sense cuz it increases your basic attack function while giving you some CDR and some magical protection...but way better if you've got other basic attackers on your team.

Rather than building into Katana first (which is fairly risky in Arena cuz outside of your ult, you don't have much mobility as Bellona), you might do the normal thing and just go into Tabi. After Tabi, get your protections (dual fine here if you want to go Urchin, for example), and THEN start itemizing as you see fit.

Ninja Tabi, Hide of the Urchin, Hastened Katana, Stone Cutting Sword, Shogun's Kusari, Ichaival. This would be against a mostly squishy enemy team (you have low pen, only from SCS), and one that has at least 2 basic attackers (to make Ichaival more directly useful as a counter). 4 AS items mean you'll be able to stack SCS and Ich quickly. You're also not the only tank, and hopefully not the main one.

In a more traditional tanky build where you aren't able to get nearly as much AS, you might have to back out of the basic attack thing from Hastened Katana, and likely Ichaival as well, depending. You could also consider having fun as a hard counter to enemy basic attackers.

Ninja Tabi, Hide of the Urchin, Midgardian Mail, Shogun's Kusari, Ichaival, Witchblade. I'm pretty sure all of those AS slows stack...Midgardian stacks, Ich stacks, and Witch is a flat value, so that should work. If it does, super funny against an enemy Baka or something.
