How to use Gergnaw

For general Logging, Gergnaw is the worker: Wood Carver speeds all Logging by 35%, and 126 Work supports it. That makes it the better pick than Bigfoot for anything outside the lumber mill. Keep it on Logging. Two loggers are rarely needed early, so build this one first.

Each column is the species' own Min–Max range at its reference level — the exact spread the in-game Aptitude tab shows (an individual catch rolls somewhere inside it). See the Stat Rankings to sort the whole roster by any of these. Attack Speed is the Skill tab's Attack Interval: the seconds between automatic basic attacks, fixed per species, so lower is faster. Every basic attack deals the same damage per second, so a quicker one lands more hits rather than more damage, which is what on-hit effects care about. Each Swift stack speeds it up by 10% and each Paralysis stack slows it by 10%.
