Talk:Abyssal Scepter/@comment-26837195-20161109075750

Some fun math:

magic damage multiplier after resistances = 100/(100+MR-MPen (10 to 25) ) (By MPen I mean MR reduction in this case)

110/(100+MR) is current abyssal scepter damage.

As MR gets higher, MPen becomes less useful

At 10 MR Reduction: 110/(100+MR)=100/(90+MR) -> MR = 10, any higher and current abyssal beats it.

At 25 MR Reduction: 175. Any higher and the current abyssal beats it.

So if you're a ranged AP carry with only 1 MR item like this one, it's usually going to be 90 MR total, some really bad ADCs who go full damage stay at 30 MR forever, etc etc.

The formula for maximum MR before current Abyssal beats old Abyssal (at certain levels)

MR = 10+(9.166*lvl)

At around level 6 or 8, old Abyssal is better at 90 MR (both mid laners buy one Abyssal) but until then, current Abyssal is better.
