I wasn't here long enough to know what that was before apparently it was changed. The description of the item Lord Domnicks Regards doesn't say anything new on what that is and i cant find anything else on the web about it besides old forums about it years ago......so what is it
ModWulf Helhammer3 votesIt pierces both the armor you get from buying items or from runes, as well as the base armor (and armor per level) that champions get
50Shades0fTrynda1 votesmaaan, coolest name i have ever saw related to this game :'D
Marshbouy2 votesThere is bonus armor and there is base armor. Base armor is the set amount that your champion is given as stats. Any armor on top of that is bonus armor, this could come from runes, items, or the champion kit itself.
Total armor penetration penetrates both of those.
Jbels2 votesIt shouldn't , but it actually shocks me that it's been so long since the change to last whisper that there are players thinking that the last whisper items having total armor pen instead of bonus is a brand new concept
SammyDayspring2 votesBase = what your champion has Bonus = what you get from items and runes Total = both
TheSandQrator1 votesEvery champion has a Base Armour Value, which is what they have naturally at the start of the game, and whatever Armour they gain from levelling up.
Literally every other point of Armour that a character gains is defined as "Bonus Armour" (i.e. Runes/Items/Skills like Leona's Eclipse).
Total Armour Penetration affects all of the Armour a character has. Bonus Armour Penetration affects only the Armour a character has that they didn't naturally gain. (And thus affects tankier characters and people who build Armour, far more than squishies, who don't.)
The original Last Whisper affected Total Armour but was too good of a choice against everyone so they tweaked it (and added additional items for it to build into) to try to actually function as more of a tank-busting item instead of an everyone-busting item.
i.e. If you built literally no Armour against someone with the old Last Whisper/LW Upgrades, its Armour Penetration would have no effect, as it didn't consider Base Armour. But now it will increase the physical damage of its users somewhat, regardless, since it's going to take their targets' Base Armour into account.
Talon121 votesBonus armor penetration was an attempt to reduce the potency of assassins by only affecting armor gained from runes, spells, effects and armor, this was considered bonus armor, while every champion has armor specific to the unit, called base armor. Bonus armor did just that, penetrated bonus armor, so say someone has base armor of 100 and bonus armor of 300, the bonus armor pen would only affect that 300 value, while total armor pen (or simply armor pen, but I will user total armor pen for ease of understanding)) affects the whole 400 value.
However, with the changes intended to ship, armor pen is likely to be stronger than before as the pen value is higher.
Another example is a unit such as an adc, with 80 armor and no armor items, bonus armor effects would have no effect what-so-ever to their defense, thus they have the full benefit of 80 armor (which is 44.4% damage reduction), but with total armor pen, this defence value is affected, reducing the protection to 34.2%. I shall assume you do not understand how armor pen works either, as it is likely you would simply assume that it removes 35% of the reduction you have, or 35% of the reduction you already have (which would be 9.4 and 28.86 respectively, however, this is supposed to be incorrect), the armor value is initially reduced by the penetration % (35% or 25% depending on the item) so the 80 armor, when reduced by 35%, becomes 52 (0.65*80=52), which is then applied to the formula (100/(100+armor), or simplifying the equation to include armor pen by using (100/(100+(armor−(1−armor × armor pen)))), which results in the same final answer. As such total armor pen affects all enemy champion units, whereas the bonus armor pen only affected units that have bonus armor from spells, effects, items, and runes.
Hope the extra info didnt hurt
TDLR: Bonus armor pen is weaker, total armor pen effects the full armor value, bonus armor pen does not.
