Why don't you get Frozen Mallet sooner? Seems like a key feature to me to make Tristanas enemies slower cause she is so slow w/o rocket jump plus it increases her health a lot?

i rather think should max rocket jump the first might as well add explosive shot level 1 2 and 3 add rocket jump then lv4 add explosive

The thing about Infinity Edge, to me, is that it requires Attack Speed to build up the chance of getting a Crit and using it at it's max. That's why I like to prioritize The Black Cleaver and Berserker's Greaves for the Attack Speed to help get a chance at getting the Crit.

There is the Phantom Dancer which does provide everything needed to use the Infinity Edge at its max, and I am considering placing it in the possible 2nd or 3rd item slot, but I think having the AD and Attack Speed from The Black Cleaver is better. The passive is more important late game and does help other Allied AD champions because it's not really Armor Pent, but Armor Reduction. So, not only are you lowering their armor for your attacks, but for everyone elses as well.

As for the runes, I like getting the Crit Chance to boost my damage once I get Attack Speed, and the Armor Pent just to have more... well... Armor Pent. I like getting Doran's Blade over Vampiric Scepter just because of all the Utility it gives you. Tristana is really squishy early game, only having 497 health at LVL 1, so I like to boost that up with the +100HP given by the Doran's Blade and to have just a little more AD so I can harass with auto-attacks more. To make lifesteal effective, in my opinion, is to get high AD and Attack Speed. Tristana has none early game, so getting Doran's Blade over Vampiric Scepter gives her a little bit more bite.

Thank's for the comment, and I'll be happy to check out your Vladimir guide! :D

Thanks for the comments guys. The real reason behind the Frozen Mallet on Tristana isn't really the slow, but the health it gives. I understand Tristana's Rocket Jump is already has a slow, but sometimes I feel it's not safe to jump at an enemy. Yes, I know, GOOD Tristana players don't just suicide with the Rocket Jump.

Nonetheless, I like the 700HP given and the small amount of AD. That's just my take on it, but I will change my guide a bit to make it a considerable item instead of an item that must be purchased for her. Again, thanks! :D

ill agree with you on the infinity edge part, but no damage is always better, early game consists of mainly farming/ harassing therefore doran blade is always a better pick then vampiric scepter, berserker greaves because of the added attack speed, in this guide there isnt any source of attack speed at all, so thats probs why beserker greaves were chosen, but tbh i disagree with the frost mallet, trist has no need for an additional slow, she already has the jump, if she prioritise her kills properly then she would have no need of it, she can just constantly jump around from 1 victim to the next, and for my item build it would be

doran's blade - boots - (doran's blade, if underlvled) - B.F. sword - scepter - berserker greaves - inifinity edge - bloodthirsters - black cleaver( if they have someone with an high armor count, otherwise i would wait it out until they do have an high armor count before getting this) - phantom dancer - for a 6th item it would range between banshee's - more damage depends on personal likings

I enjoy the guide, but I have a few questions
Concerning Runes:
Wouldn't it be more viable to start with Attack Damage marks/quints? This starts you with +15 AD from spawn. This allows you to take a Vampiric Scepter first. Isn't this more viable of a solution?

Items:
1: Wouldn't a rushed Infinity Edge be better?
I mean unless the enemy team or your lane has a load of armor, it's kind of useless to get the Black Cleaver.

2: Why prioritize boots over your other purchases? And why Berserker's Greaves? Boots of Speed seem more fitting for Tristana, due to her slow starting statistics.

Thanks in advance!
