Haunting Guise - a very situational item

[quote=Searz]You focus on both flat and % MrP on a support/damage caster? Just no..[/quote]

[quote=The_Nameless_Bard]I only had the Void Staff because the enemies were stacking MR Edit: I was solo queue and no one else picked a caster, so I needed to deal more magic damage.[/quote]

[quote=Searz]That explains it.[/quote]

[quote=Yagamoth][quote=Searz] [quote=Yagamoth] Sidenote: -30 Magic Resist means, that the enemy takes about 30% MORE damage, that's more than True damage [http://leagueoflegends.wikia.com/wiki/Magic_Resistance][/quote] No.. It reduces the damage the enemy MR reduces by 30 percent units. If the target has over 30MR that is. [/quote] I don't quiet understand what you mean. If you HAVE -30 (minus 30), it's increased by 30%. However as someone already pointed out on the first or second page, the Reduction is applied before the Penetration, thus making the HG less worthwhile than I expected it to be against low MR opponents. After some testing I'd say, HG is never(!) worth more than straight AP + straight health. Because, after the opponents realize, that you deal a ton of magic damage, they will get more MR (unless they are dumb, but then it doesn't matter anyways since defeating dumb people is usually a non-issue). And as soon as they get about 1 MR item more, straight AP is more worthwhile even in the theory. I do like the idea of HG, but I really think by now, that you have to build your TEAM around this idea to make it worthwhile.[/quote]

[quote=Searz]Reduction is applied [u]before[/u] penetration. That means it's currently impossible to make a champion's MR go negative.[/quote]

[quote=The_Nameless_Bard]However you can deal true damage, which is the usual reason I build it on champions with somewhat low AP ratios.[/quote]

[quote=Searz]Yes, but as I've said many times; [u]Ratios can't be considered low unless they're compared to the flat damage of the spell.[/u] (just a reminder) Even spells like [[Absolute Zero]] with a 2.5 AP ratio has a low ratio in comparison. I think the border for a low ratio goes somewhere around 23-24% per 100 flat damage.[/quote]

[quote=caucheka]yeah yeah we've got it.[/quote]

[quote=The_Nameless_Bard]Let's say the enemy has 30 MR: Haunting Guise innately penetrates through 20 (66.7%) of that, while a Void Staff only penetrates through 12 (30 X .4 = 12) of it. the math: a Void Staff is NOT better than Haunting Guise unless the enemy has [b]MORE THAN[/b] 50 MR. Because until that point the innate 20 penetrated by the Haunting Guise is actually more than or equal to 40% of their total MR. 20=100% 30=66.7% 40=50% 50=40% HG is actually a better choice than a Void Staff unless they are stacking MR. Abyssal Scepter provides an identical effect because removing 20 of their MR is actually the same as penetrating through 20 of it.[/quote]

[quote=Searz]But everyone knows that Void Staff is a lategame item. By the time you usually have it enemies will have about 80+ MR and it will be a great source of MrP.[/quote]
