Which is more effective? And can it go together?
I heard from another member that they dont (I think Zilby) but it doesnt make sense to me.
Basic math (mistakes incoming), I am not counting auras or health.
Random god with 100 physical defense.
You have an item that reduces physical defense by 10. Another item that goes through 10% of physical defenses.
100/10 is 10
Reduced amount is obvious at 90.
With both items it would be-
100-10=90
90/10 is 9.
With 200..
200/10=20
200-10=190
190/10 is 19.
Even though its only 1 point down, its still more effective. Isnt it?
God i hate Math. If anyone could do this with items from the game feel free to.
Maybe it's because I used higher numbers but if we have exe at max stacks titans penetration was only 2/3 (aka instead of 33% read 22%).
Normally Titan's Bane gives 33% penetration. At max stacks, The Executioner offers 24% protections reduction leaving 76% of the original protections. 33% of the remaining protections is 25.08% meaning you're bypassing 8% less of the target's original protections.
However, The Executioner also reduces enemy protections by 18. Thus Titan's Bane doesn't get to bypass 1/3 of these protections (ie: 6). Perhaps these 6 protections made up the 3% of the original protections difference between our results (assuming your example used ~200 protections as its base).
however do read carefulyl as sometimes it can be a bit vague
[*] Titan's Bane+ The Executioner=6 + 8% lost penetration

uhhh..thx. But u couldve just said "hey look at my item guide".
I wasn't actually irritated, I was trying to be playfully sarcastic. Sorry about that, hard to get my tone through the internets <3
I literally wrote that guide so I could stop answering questions like this lol.
Anyways, this is literally straight copypasta from the first section of my guide explaining stats and terms.
As to answer your question: flat penetration =/= protections reduction.
Void Shield and Brawler's Beat Stick offer two different kinds of penetration. Void Shield reduces enemies' protections by an amount while Brawler's Beat Stick
allows you to bypass them. Here's the difference: protections reduction affects the enemy's protections meaning your whole team will do more damage to them with physical damage, a percent penetration items will let you bypass a smaller percent because you have reduced their protections. Flat penetration just lets you bypass however much protections it equates to (eg: Brawler's Beat Stick lets you bypass 20 protections). This does not mean you have gotten rid of their protections, your damage will just ignore it. Percent penetration items will still take this penetration into account.
So when is this inefficient you might ask? Say you grab Void Stone to help you win lane in mid. The enemy mage has a default 30 magical protections at every level (standard for all mages). Void Stone will reduce their protections by 15. Say you're then choosing between Spear of the Magus and Obsidian Shard since Void Stone doesn't offer enough penetration for tankier targets. Which do you choose? Obsidian Shard offers 33% penetration, which in this case is 15/3=5. 5 flat penetration for that target. This is half the value it would have given had you NOT bought Void Stone. Compare this to Spear of the Magus which has 15 flat penetration. Spear of the Magus with Void Stone will let you do true damage to the enemy mage, even without the stacks.
So situations aside, how much inefficiency can you realistically produce with penetration reduction + % penetration items? I'll make a list (assuming max stacks on each item).
As you can see, the amounts aren't huge, but against squishier enemies with only 30-50 protections they make a difference.
That is all.
