Didn't get acceleration or echo shrines in this map (just from the enchant), so it's a pretty average experience. The enchant shrines lasts around 22 seconds I think. That's with gull, blunderbore and full shrine atlas.
Started this build today, and having a blast with it. There is a LOT of room for improvement. Not even close to res capped, and -40% chaos. Just some relatively basic gear to get enough strength for blunderbore.
The only expensive part is the staff enchant, because of the crazy rune prices atm.
