Straight Speed Thanny

Eh, this isn't exactly troll. It's not efficient and has issues, but doesn't seem like the creator just threw items together. There's a bit of thought process going on here, but definitely some items need to be dropped.

As such, I'll take some time to explain the issues, and allow for the creator to respond.

FYI THENatDad, not sure if you're aware, but the common builds for Thana focus mostly on his ability damage. Granted, I've seen some good players use some unconventional items for him (e.g. Hastened Katana) and do well in teamfight modes. This would not be a suggested build for Conquest, though, to be clear.

Some inefficiencies come into play when you mix true ability items (e.g. Jotunn's Wrath) with basic attack items ( Poisoned Star, Hastened Katana.

When you do build crit (which is typically not suggested on Thana), you really always want to build at least 2 crit items and get your crit chance in the realm of 50%. This makes the crit at least semi-reliable. At only 20% (soon to be 15% when Season 6 hits in a couple of weeks), you're getting very little out of it in most situations. So, either build 2 crit, or not at all (suggest not at all).

I can see Heartseeker being functional (not preferred, but can work) in a mode like Conquest, since you'll have a chance to build stacks easily with jungle camps. In teamfight modes, you won't want to expose yourself in melee range (where it'll be very easy to hit you with a variety of abilities, especially AOE abilities), when you don't build any protections and every minion wave is contested. You likely just won't be able to safely build stacks there, unless you're playing against people that don't know what they're doing.

A typical build for Thana will involve the mace tree, with focus on power and sometimes/often CDR. Since his base damage and the damage built into his Death Scythe is so good (along with the fact he can execute enemies at lower health), he can build bruiser (with some protections) and remain effective. He also doesn't need much flat pen due to Scent of Death, but he'll benefit from some alternate forms of pen (either protection reduction such as via Void Shield, or % pen from Titan's Bane). Ancile is also a decent one if you need magical protection, or you can also consider dual protections such as from Mantle of Discord.

So, in general, it would be suggested as a vanilla Thana build to get rid of HS and Katana, and replace with items such as those mentioned above...though you can add Bloodforge and Brawler's Beat Stick to the list of functional items.

But if you really like the Hastened Katana effect, then since you'll be dealing a decent amount of damage from up close, I do strongly suggest some protections to help your survivability. You might also consider the use of Stone Cutting Sword for a different form of pen.
