Newbie Theorycrafter questions

[quote=Zwergner]So I'm doing some theorycrafting to make my own Tristana build, and I noticed two things that didn't make sense to me. If someone could provide some answers, I'd appreciate it. #1 Attack Speed. Recurve Bows claim to add 40% attack speed...naked level 18 Tristana has 0.99 attack speed, and one Recurve Bow brought her up to 1.25. This is more of a 26% speed increase. Another Recurve Bow brought it up to 1.52 which is about 153% of the original speed, so about a 27% increase for the second one. I kept going to the cap, each Bow adds about 26-27% attack speed instead of the advertised 40%, why? #2 Armor Penetration Runes. if I have some ArPen runes equipped and I open up my character sheet, is it normal for my champion info to report my Armor Penetration as 0 | 0%? Because that's what it is. So are ArP runes broken or are they factored in after whatever my champion info reports? Or was it because I was in a practice game? Thanks.[/quote]

[quote=caucheka].99 * 40% = .396 .99 + .396 = 1.38 .99 + .26 = 1.25 .26 / .99 = 26.3% .26 / 40% = .65 huh... on the second bow.. 1.38 * 40% = .552 1.38 + .552 = 1.932 1.25 + .28 = 1.53 .28 / 1.25 = 22.4% .28 / 40% = .7 anyway, for the second one, i think its probably that it doesn't appear on the character sheet for some reason... to check you would have to compare the damage that you deal on one attack vs what your damage is listed vs the targets armor.[/quote]

[quote=Winterbirth]i think for the runes... they kick in after like 5 min... probably less.. but not as soon as the gae starts... my sivir rune buil is full atk speed and at the beginning i stilll start with like a .5 but later on like.... idk.. 5 min in the game. my atk speed jumps to .90 without and items of course... so... yeh... and i think recurvee bows is not 40%..... lol[/quote]
