Lady Geist Build by Sharky

First buy Restorative Shot for an increase in sustain and damage.

After buy Headshot Booster which increases fire rate and gives bullet shield while adding bonus headshot damage.

Next buying Sprint Boots for more movement speed because of the low base geist movement speed and extra weapon damage.

The last two items for lane Mystic Reach and Mystic Burst which increase the range of all abilities and increase spirit damage with a little weapon damage increase.

First buy Enduring Speed and Return Fire for more survivability and mobility and then save for Headhunter for the first mid game power spike.

Depending on the enemy team composition Spirit Armor and or Bullet Armor will make you more tanky and give a bit of damage to spirit/bullet.

Bullet Resist Shredder is good for if the enemy team has base bullet resist or started buying armors if not then prioritize Mystic Shot and Berserker (depending on enemy comp).

Improved Burst for a increase in spirit burst damage and added weapon damage and then Improved Cooldown to get life drain up faster for more constant shutdown.

Another good choice but optional Bullet Lifesteal if your team lacks bullet damage this will be a good addition with all the gun items.

After entering the late game Leech makes Lady Geist a very hard target to kill and makes her good for mid range damage and poke while having alot of sustain making her a tough solo opponent.

Improved Spirit Armor and Improved Bullet Armor upgrading one if not both is for more added sustain.

For the last two items you must pick depending on if you want to go for more bullet or spirit damage Frenzy and Mystic Reverb (on Malice).

Debuff Reducer or Debuff Remover are great options against teams with large amounts of debuffs and stuns, especially against Knockdown and Slowing Hex.
