Vim

Vim is the resource used by Reavers and Corruptors. Vim does not regenerate but is instead regained in several ways, all involving combat. Fatigue plays no role in determining vim costs. The vim pool grows by 4 points every level and is not influenced by any stats.

Ways of regaining vim:

• Kill bounty: Each kill returns one point of vim per 20 Willpower.
• Kill refunds: If you kill something directly with a vim-using talent, the talent's cost in vim is restored. This only works with straight damage -- infecting someone with a disease won't return any vim this way, even if your victim dies from it three rounds later. Though if you kill something with a Bone Nova, for example, you will get its cost refunded.
• Special Talents: Some talents can also restore your vim, but they either need a victim (Drain) or require you to be hit (Leech).
