Weighted
Weighted refers to the way spells/items/abilities select targets. Any spell/item/ability (with the notable exception of one unique that avoids targeting the top stack) that is described as targeting a random stack(s) will prefer to target the largest stack(s) by NP instead (usually but not always the top stack(s)).

The game code chooses a stack by giving the top stack a 50% chance of being selected, and then halving the chances after that until you are out of stacks.
| Stack # | Chance of selection |
|---|---|
| 1 (aka top) | 50% |
| 2 | 25% |
| 3 | 12.5% |
| 4 | 6.25% |
| 5 | 3.12% |
| 6 | 1.56% |
| 7 | 0.78% |
| 8 | 0.39% |
| 9 | 0.19% |
| 10 | 0.01% |
