Item categories

1Early Game L>R
Author's category · 9 items
1. 1
  High-Velocity Rounds
  Makes your gun a lot better in lane. With the investment its 17% more damage on gun very efficient and builds into opening.
2. 2
  Extra Regen
  You have 1 base regen and this builds into healing booster so it is very good most lanes early. Can buy opening first if healthy.
3. 3
  Opening Rounds
  Built from High-Velocity Rounds
  Extra 7 spirit for 800 is very good and the passive lets you clear wave faster and have better poke in lane.
4. 4
  Trophy Collector
  If you plan on playing actively. Replace heal booster as the 4.8k green spike.
5. 5
  Enchanter's Emblem
  Overstatted item. Buy every game.
6. 6
  Healing Booster
  Built from Extra Regen
  You have a lot of healing and it buffs radiant regen when you buy it.
7. 7
  Improved Spirit
  Overstatted item. Kelvin has very good scalings and this is the most bang for your buck spirit power in the game.
8. 8
  Torment Pulse
  Actually does quite a lot of damage. Faster camp clear. Make sure to stand close enough to enemies to trigger it.
9. 9
  Healbane
  Anti heal is a must in most games. Also +7 spirit power is solid for 1.6k item. Can sell once you have spirit burn.

3Damage Core L>R
Author's category · 3 items
1. 1
  Radiant Regeneration
  Give the build the movement speed it needs while also giving you a lot of sustain.
2. 2
  Rapid Recharge
  Rapid recharge is extremely strong. Make your bombs very powerful and lets you spam them a lot in fights.
3. 3
  Escalating Exposure
  Escalating is extremley important due to the shred that it provides and it synergizes very well with beam.
4Mid Game Spiritoptional
Author's category · 5 items · Alch fire if hitting good ults

3. 3
  Alchemical Fire
5Mid Options

9Category 9optional
Author's category · 6 items
1. 1
  Tankbuster
  If you have the slots for it sure. Buy after max bomb.
2. 2
  Mystic Vulnerability
  It doesn't neatly fit into the second row so I put it here but you can just queuee escalating and it will auto buy it.
3. 3
  Slowing Hex
  If you really need it for stopping certain characters from using certain abilitites it can be very strong but I find most character who don't like being hexxed buy dispel.
