Ifrits Cauldron, some questions

[Deli]

was going for Ugg, Rancor and Ifirit's map.

Ifirit coffer dun seem hard if u know how/where to go. The problem is I dun know how to get to the bottom 3rd basement where there are 2 coffer locattion. ><

Tried attempting RancorDen too. But dun know how to get to the place with most coffer location. Thru Ugg Temple?

Ugg is hard. Can thf hide ability cancel tonberry's hate? If it works thf can be used to pull trains aside. BTW, hide works for bombs.
