Mak just seems to have so many viable builds I stumble into crazy ones by accident. This one beat out a Jumbo Wok Jules and Shielded Ice Club + Fort Pyg by having so much regen it survived against them deep enough into the sandstorm for them to lose to that, which stunned me both times. It was actually using Oil Lantern for most of the run – built it arond that, basically because the self-poison items are a good way to trigger a lot of regen gains fast – but I replaced that with Sunlight Spear for the last couple of days. I might not have needed to, Oil Lantern was stiill doing great even in the late-game, but when you get a diamond copy of an item that turns regen into damage on a build where you stack this much regen, you use it.
