DC needed for Epic Locked Chest Farming

[Sadus]

I am planning on making a WF 16 Soc/2 Pal/2 Rog Farming toon.

I have been away from the game for a while. So I was thinking about possible chests that might be farmed like the locked chest in the Titan raid pre-raid.

I am not familiar with content past Giant Hold... so I don't know if there are some other locked chests that would be "farmable".

Currently, this character is in "theorycraft" phase.. so I would appreciate the most difficult DC with maybe a extra to make him a little flexible on possible future content. As this will help me figure out how much INT I need to start with etc.. to ensure I have enough skill points to get my Open Lock high enough to hit those DC's

Also, What is the Max UMD I would likely need... as I could spread some skill points around on different levels... if I don't need a 23 base UMD to use high level divine scrolls/wands/overcome Item alignment and race restrictions.

I figure... with the 32-34 CHA this toon will have it would hit 36-37 UMD with Rogue skill boost before items/feats.
