Hi everyone.
I've been using this mod for a month and tested it on 5 accounts, with different settings, to get a feel for what is safe to do.
The first 4 accounts got banned; the fifth is going strong for over 10 days. Here's my analysis:
Story mode: Never use "Install win" on all fights. Tried that one; did everything until Act 9 in 24 hours. Got banned. Is ok to use in some very troublesome boss fights, but be careful; try to win the fights yourself. Most of them are not that hard. What worked best so far for me is using a small multiplier for attack and defense (x3 or x5. I think even x10 is safe, but do it only on very hard fights. Dumb enemy is generally ok. I always use "dumb enemy skill" on every fight, makes them easier, and so far so good. Overall, try to always use your best fighters, and update them regularly, so their checks won't trigger.
Monthly events: pretty much the same as Story mode. Use best fighters, lowest multipliers that make it easier for you, dumb enemies on hard bosses, Dumb Enemy Skill is ok.
Special Quests: This is one that gave me the most bans, so you need to be careful. I'm testing them little by little in the latest account I created. So far done Shooting Stars and Revenge of Legends. Lowest multipliers, increased maximum to x10, dumb enemy skills, and in some hard fights, dumb enemies. On the banned accounts, I used it in Necropolis and Epoch of Pain, with big multipliers because the enemies there are tough, and eventually got banned. I'll try them again on the current account, with the same settings I've used on the other two, and I'll report back. But those could take a while; they are long. Never use install win in those; I believe they can detect that easily.
Solo Raid: done daily with x10 multipliers, dumb enemy skill, and so far so good.
Arena, BGs, Alliance Quest and Wars: Tried once with mods on, and got banned. Haven't tried again, so I'd say so far that it's not safe at all, so either play them normally or don't play them at all.
Towers: Tried once but got banned. Could have been because of the other game modes, so can't be sure yet if it's safe or not, but if you want, try it with small multis.
Haven't tested yet in incursions.
It takes time to test all modes and get a definitive answer on what's safe, and so far I've always been banned during the night, so I try the game mode and wait for the ban. When it doesn't come, I try another one.
So far, that's what I have.
Good luck.
