I fail around wave 330. Talisman all 80+ rarity, wizard level 3k+... I don't think its beatable. Your xp is super low though for being wave 300.. which is surprising. Usually i'm over 250m (before modifiers) at that point...
Actually, now that i think about is... someone was saying they beat endurance (or got really far) earlier utilizing shrine of blades (-90% monster hp per activation) and wake of eternity spam... combined with very, very high grade gems. May be do-able then....maybe..
Wake of eternity combined with the talisman specials that increase its damage done could do it... i think rarity 100 gives +10% WoE damage.. so 8 of those would make WoE remove 105% of enemies health. Would that do it? Or does it cap?
On a sidenote: anyone know how people are topping 1T+ per level? If i play haunting, full modifiers, anger all waves to 999 monsters and then some (so around 500 base xp per monster)... I still only cap at 50B-100B xp per level (and my talisman gives me +100% total xp...). Then endurance's 25% xp modifier hits me so its hard to get much beyond that. I don't see how its possible. Also, i drop grade 30-40+ gems for heat bonus whenever that comes up too.... still can't get close. I'm not sure what else to do..
If there's an end, like 1337 waves as in prior games, it's totally doable, with any luck.
If you get a couple (I think 2 with 40% reduction is enough) spell cooldown reduction sparks, you can reduce your freeze spell to a cooldown LOWER than its duration. With some 90% slow (grade 20 or so prismatic, since they will also give heal reduction, armor reduction, and mana, being great utility) gems firing at "closest to orb", you can keep a permafreeze going on while you spam Wake of Eternity.
However, I can't imagine a reason to do this, past bragging rights. As it stands, it takes me over an hour to clear a normal haunting-max-trait stage before I even get the option to go to endurance.
It seems, from this thread, somebody beat endurance with a venon shrine. I had 3 shrines of blades all of them would cut life by 90%, and wave 300, unreanged, was unbeatable by my level 35 gem (and they healing on the haunting difficulty at this level is really huge on mobs with the healing trait).
The pic I posted was a run from around level 430ish. 300+ million exp only because I only killed about the first 220 waves then cycled and called more when I was screwed to see how high the cap goes. I figured shrines would be one way to do it, I just need to level up more. I only have a couple level 90+ talismans and just hit lvl 800.
I also just found bloodbound gem skill since then and that makes a pretty strong quad. At least for my mana gems, the triple without bloodbound seems to be pretty much just as good but I haven't really tested it.
It's easy to get to wave 400-500 if you do your first 200 properly and get a grade 45 gem by wave 100, its very time consuming tho since most if not all computers lag like hell when you are enraging minion waves to 2b armor+999 minions a wave and loads of becons spawn unless you fill the map with towers
