Overview
This build was created by Hydration. To find it in game, search for "Mobalytics - Yamato by Hydration"
Yamato is an assassin that can be played both Spirit based or Weapon based. This build is a hybrid between the two that focuses on having good burst damage while still being able to put out consistent damage.
Early Game
First buy Ammo Scavenger and begin stacking it to give you strong poke in lane.
Pick up Mystic Burst and Infuser so that you are able to get better trades. Make sure to activate Infuser before casting Power Slash (1).
Extra Health and Enduring Spirit help you not get one shot by enemy burst damage and all ins.
Mystic Shot and Cold Front are your main sources of damage outside of Power Slash.
Mid Game
After buying your early game items start saving up to 3000 souls, here you want to buy Torment Pulse as your first Flex Slot purchase.
Fill out the rest of your weapon slots with Slowing Bullets and Soul Shredder Bullets.
Next you buy Spirit Lifesteal and Healbane to enable you to get involved in fights that aren’t just duels.
With a big focus on burst you need to go for Improved Burst, it's fine to get this later as it deals % max hp damage and at this point it will have high effectiveness as everyone’s health pool increases.
If you have another flex slot consider picking up Extra Spirit and upgrade it as you get more souls.
Late Game
Later in the game you begin buying cheap but effective spirit items like Mystic Vulnerability and Duration Extender.
You can choose to upgrade Shadow Transformation (4) with Superior Duration.
If you are strapped for slots you can upgrade Extra Spirit into Improved Spirit and Boundless Spirit.
If you have too much money you can consider some of the following items:
Mystic Reverb - This is the best item for increasing your burst damage.
Refresher - Try to only buy this after buying Superior Duration.
Situational Items
Warp Stone gives you an extra bit of mobility.
Ethereal Shift is your best answer to enemies’ Silence Glyph.
