I got 98 on Hardcore Expansion Season Ladder 1 in 15 days and 99 in less than 1 month
I got to 98 in 15 days doing Chaos Sanctuary Runs Only.
91-94 was 1 day
94-95 was 1 day
95-96 was 2 days
96-97 was 4 days
Contrary to popular belief Baal, Diablo, and Nihlithak are NOT the best sources of exp at 96. Level 88 minions are without question the best source of experience.
This is because despite the monster level exp diminishing return from monster level 88 minions, the sheer volume of them and the speed at which you can kill them in Chaos Sanctuary and now Arachnids lair dramatically exceeds the exp yielded from Nihlithak, Diablo, or Baal.
I can say this definitively because i measured chaos runs at each level starting at 90+ in a spreadsheet tracking my exp with 3 variables:
Start Exp
Exp Before Diablo
Exp After Diablo
Using these i measured the ratio of % exp yielded from runs as Monster Exp % Vs Diablo Exp % as a benchmark to determine at each level if my strategy of speed “minion hopping” in Chaos Sanctuary runs was still the superior method for gaining exp.
96 and below without question “minion hopping” in chaos sanctuary with teleport in players 8 at lightning speed is by far the fastest method of exp gain as my measurements showed even at 96, 70-80% of the exp yield was from minion packs and only 20-30% was from diablo.
For those who know what “topping” is these measurements were done against doing top 1, top 2, and top 3 diablo as well as top 2 and top 4 baal in players 8 games.
To recap thus far, killing monster level 88 minion packs in high density and super fast to find areas like river of flame, chaos sanctuary, and arachnids lair are already incredibly good at getting to 97.
As for 97 the diminishing return penalty increase is just enough to where i had to adjust strategy slightly and find baal games (easy way to find player 8 games) with which i could usually get solo p8 experience killing the minion packs in river of flame, chaos sanctuary, and arachnids lair and depending on what players in the game sometimes top 1, top 2, or top 3 diablo exp.
Each Solo Minion Kill in Players 8 at 97 yields about 3,000 exp which sounds bad however if you factor in killing the whole pack solo:
3,000 * ~5 to ~10 minions = 15,000 to 30,000 exp which is about the same as nihlithak and almost as much as a top 3 diablo or top 4 baal kill which are around ~40,000 exp.
Thus at 97 i still opted to go for solo speed killing level 88 minions in chaos sanctuary, river of flame, and arachnids lair and either do top 1, top 2, or top 3 diablo (depending on who was in the game).
Level 88 minions were still equitable exp therefore to Diablo, Nihlithak, and Baal even at 97 so in reality level 97 did not feel hard essentially i was still essentially doing the same strategy for 96 and below, just getting more solo p8 exp instead of shared p8 exp.
In my personal opinion the only level that felt kind of difficult was 98 but even then didn’t even feel that hard once you have a super fast strategy in place.
Mind you I did all this on Hardcore all in random public games, no pre organized teams, “helpers” or “feeders” and thus is a good benchmark for evaluation as i essentially was a random solo player just playing with whoever was publically available.
Now with all that backstory and information as a baseline let me mention that I am not saying that “Terror Zones” are a “bad idea.” What is a really bad idea is the current implementation of monster levels, it will just be the equivalent of cows to 99 all over again and the whole reason why the monster level diminishing return was introduced in the first place.
Here is my exact suggestion:
Terror Zones are normalized to area level 85 for their duration.
-Terror Zone Normal Monsters are level 85.
-Terror Zone Minions are +3 level = level 88.
-Terror Zone Super Uniques are level 93.
-Terror Zone Super Uniques as well as Baal, Diablo, & Nihlithak have their experience slightly buffed
-Terror Zone Super Uniques as well as Baal, Diablo, & Nihlithak yield their full solo experience even if killed in party so that there no longer is an incentive to leave and reparty to “top baal” or “top diablo” for more experience due to natively gaining full undivided boss exp in party.
