Slither in and assassinate enemies
With a powerful weapon (and deadly venom to match), Vyper can slither into the back of teams and assassinate high-priority targets in a storm of bullets.

Each phase lists what to buy since the previous one; the % on a card is how much of the build's score you lose without it. Lit pips under an ability are its upgrade tiers (green: new in this phase). Hover anything for details.
For each net worth, the optimiser searches items and ability upgrades that maximise the score: damage per second against the reference enemy × effective health^weight, averaged over short, standard and long fights, each both fresh and mid-match (long cooldowns still recovering from the previous fight). Each checkpoint starts from the previous one's items, so the builds read as a path.
Gun, spirit and hybrid differ only in where the offensive souls go. The fight assumptions (accuracy, distance, the target…) are on the Data page and adjustable in the simulator.

Throw a dagger, dealing
spirit damage and applying slow.
Every subsequent dagger against the same target stacks in
spirit damage and slow.
• Each dagger that hits within StackDuration adds a stack (up to MaxStacks): later daggers deal DamagePerStack more per stack, and the T2 bullet resist reduction grows per stack.
• The T3 refund is applied as a shorter charge cooldown (refund share × ability hit rate). The slow is not scored.
Values are base values with their scaling; the simulator shows them at a chosen net worth and build.
Boons come with net worth; gun DPS is every bullet hitting at close range, no headshots. Items and investment bonuses come on top (see builds).
35 boons in all, the last at 49.2k souls.

Souls spent in a category (each owned item's full price) unlock the highest tier reached. The biggest step is at 4.8k; after it each tier adds less per soul (weapon: +17.5% per 1k souls up to it, +5% per 1k to the next), so piling souls into one category has diminishing returns. Builds and tier lists include it.
