Missables before WoR in 2.0?

Because it's been a long time since I've played this mod (and even longer since I played vanilla), what can't I miss before heading to the floating continent?

I have Seraphim and Golem. Is Zoneseek still WoB?

Water Rondo with Mog? Intangir? Ultima Weapon? Stray Cat & Grenade rages?

Also, has the Chainsaw been moved? I got a Thief Glove from behind the clock in Zozo.

Thank you!

2.0 is completely awesome... by the way.

I can't answer all your questions, but I can answer some of them:

• Yes, Zoneseek is on WoB, at the same dude you bought Golem from, but he only sells it after IMTRF, so that's maybe why you missed it.
• The mob you know as Intangir no longer exists. There is a boss by that name on the WoR, but not missable.
• Yes, Water Rondo is missable as far as I recall.
• Grenade rage no longer exists, but Stray Cat's does, and it is missable unless you fought it once and made it available on the Veldt.
• Yes, the Chainsaw has been moved to the WoR.

Thank you, that is incredibly helpful!

I was stressing the most about Zoneseek and Chainsaw. I bought Golem just now, but didn't try talking to the guy selling it a second time. Whew.
