This probably isn't needed. i assume most have Misty down by now but i don't believe iv seen much in the way of wave 30 misty runs. was toying around and ended up at wave 30 without much issue.
Not much to note if you know my old build.
-Gas trap in the west. Effective edge of the gas trap needs to reach the edge of the tree on the north wall so that no mobs can walk past. This prevents any genies from going from west to north.
-at the end of the later waves when only genies are spawning, you'll have to run around manually igniting the gas traps. its annoying.
-key to having an easy time with spiders is making sure the inferno trap is being buffed when it is lit. I manually light it every chance i get.
stats need to be high to go all the way to 30. around 1200/2400/1k/1k on the squire. More is always better. Trapper stats should be high on Range because a genie cannot kill a range capped gas trap.
Ideally 1200/2k/800/800 at least on the trapper to get all the way to 30. more is better.
This build uses a gas trap, darkness and explosive in front of each blockade (a bit off) and stacked directly on top of each other. no staggering traps except in the west where the gas trap is farther north so that its effective edge touches the north wall. The explosive trap is staggered to the south of the west gas trap.
betting this build will function just fine with up to 4 players with just one minor adjustment. if i get a chance to test it, ill post it later.
To do this with with more players you should make an adjustment. delete the far north harpoon and add an explosive / bumper for spiders.
- Quick note. You will want to make sure that genies are within range of your harpoons when they are stuck on the back edge of the gas trap in all cases except for with the duo + build with the exception being North because the one harpoon with lane LoS was removed. You may let it slide for the West because it requires that the gas trap be touching the edge of the north wall.
